Product Information:

TITAN Lithium 12.8V 300Ah Battery

12.8V | 300Ah | 3,840Wh

521mm long x 238mm wide x 218mm high

Uncompromising in energy capacity and quality, our 300Ah lithium is the perfect choice for those who need 3.8KWh of capacity. The equivalent of 852Ah in lead-acid, just one of these batteries can give you weeks off-grid camping or many days of power without solar input when used as home storage.

We've included Bluetooth at no extra charge for round-the-clock accurate status reading and state-of-charge monitoring.

TITAN Batteries use Lithium Iron Phosphate cells

TITAN LiFePO4 batteries are inherently safe both chemically and thermally, and do not use rare materials like Cobalt or Nickel. In return, we get a slightly lower cell voltage of 3.2V per cell (4x cells = 12.8V), and a lower energy capacity compared to NMC (Lithium nickel manganese cobalt - the cells used in EVs), however LiFePO4 are much more stable at a chemical level, and have much higher lifespans - our batteries can last between 2,500 and 10,000 cycles (depending on use) - NMC is typically 1,000 to 2,500 cycles.

The omission of Cobalt vastly reduces the chance to start thermal runaway. Many now consider LiFePO4 to be safer than lead-acid thanks to their stability and internal control. They can be used in any orientation (e.g. on its side), although on its base will give the best performance. They contain absolutely no acid, generate no gas emissions and are recyclable.

Massive Cycle Ability

TITAN batteries can be cycled (1 discharge + 1 charge = 1 cycle) between 2,500 to 10,000 times. The amount of cycles corresponds to how deep the discharge is - this is referred to as DOD; Depth of Discharge). If you discharge 100% of the capacity every time you use the battery, it can do this 2,500 times before needing to be replaced. The less capacity used, the higher the cycle life.

In terms of measurable life: if you discharged this battery 100% every day of the year - 2,500 cycles ÷ 365 days = 6.8 years expected lifespan

To put this into perspective, the highest quality lead-acid gel battery (gel has the best cycle count of lead-acid) can do 350-400 cycles at 80% DOD.

The Equivalent of SIX Lead-Acid Batteries

To get a similar capacity in lead-acid, you would need SIX massive, heavy 142Ah batteries (Exide ER650) in a parallel connection to make 852Ah. Just one TITAN 300Ah can save a huge amount of space, weight, extra wiring and has the added benefit of no gassing, so can be placed anywhere.

To compare accurately, we only use Wh (Watt Hour) capacity ratings - Ah (Amp Hour) ratings unfortunately do not take battery chemistry differences into account: TITAN lithium batteries use 100% of their capacity (~90% with Gel, ~75% AGM & ~60% traditional flooded lead-acid). This coupled with lithium's inherent energy density, means our batteries have over double the useable capacity compared to lead-acid batteries.

Compatible With Existing Equipment

Our most asked question - can lithium replace your current lead-acid battery? TITAN lithium batteries are designed as a direct replacement of lead-acid batteries with no need for new equipment. For more detailed information, please check out our FAQs

Our lithium batteries are for running equipment only (i.e. deep cycle use) - they are not designed for engine starting.

Lithium Prismatic - Class A Automotive Cells

All TITAN lithium batteries use the highest quality lithium cells available. In doing so, we can achieve better performance, higher BMS thresholds and a better overall lifespan compared to others.

We use prismatic lithium cells (they look like a long, thin rectangle) rather than cylindrical cells. Prismatic cells are more expensive and harder to make than cylindrical, but the benefit is a higher quality, higher capacity and potent battery. As all battery cases are squares, our cells fill out all available space within which allows us to boast higher capacities over other brands that use cylindrical cells.

Cylindrical cells can waste a fair amount of internal space as circles put together will always have a gap, and are far harder to repair as they use a lot of spot welding in their design.

What about the cells getting too warm? When discharged at the full BMS allowance, we found all of our batteries to reach a maximum of ~45°C - well within the specification. For lithium to fail, the cell temperature needs to get to around 100°C. As our prismatic cells use aluminium for their outer case, any heat is dispersed with ease. And an added benefit is prismatic is a lot more efficient with heater options - heated options that use cylindrical cells means the internal cells that aren't near the heater mat will not get sufficiently heated and can lead to early failure.

lithium internal BMS icon
Battery Management System Built-in

All TITAN batteries have their own BMS built-in. A Battery Management System (BMS) is a circuit board that is mounted on top of the internal cells inside the battery which is connected in between the cell terminals, and external battery terminals. The BMS controls and monitors everything with split second accuracy to ensure the battery cannot be damaged through normal day to day use. TITAN BMS currently has a market leading 11 protections built-in e.g. over discharge protection, over voltage, under voltage, temperature protection and short circuit protection to name a few.

All protections are temporary and are designed to self-reset or reset when the battery is put on a charger.

TITAN lithium's BMS has one of the highest rated BMS allowances on the market thanks to the use of the best quality materials and internal workmanship.

Heater Installed as Standard

This 300Ah lithium battery comes installed with a internal heater mat that surrounds the internal cells, which enables the internals to warm up in freezing conditions. All lithium batteries do not charge when below 0°C in order to protect the cells against damage that may occur - options with the heater installed will activate when the internal battery temperature is ~2°C or lower, and there is an incoming charge current to the battery. The heater is powered by the incoming charge from the charger, so there is no extra drain on the battery itself. The heater will then aim for 10°C, and will switch the incoming charge from the heater to the cells for the perfect charge, whatever the weather.

Battery warm up time will vary on the type of charger and the temperature, but on average, expect an added 20 minuets to your charge time.

The added heater does not affect performance in any way - the battery can and will be able to discharge in -20°C temperatures.

We recommend heated options to those who plan to use the battery in winter months, or will go to colder climates in autumn, winter and spring.

Ultra Lightweight Lithium - 28.8Kg

There is no one single lead-acid battery that can store 3,840Wh in capacity - to get near the same capacity using two lead-acid batteries would weigh a massive 140Kg (2x Exide AGM EP2100 *this does result in 4,200Wh - it's the closest we could get), and would take over four times the physical footprint. A 111Kg weight saving means a huge difference when traveling abroad, as well as offering better MPG on vehicles.

M8 Threaded Insert Terminals (Bolts into battery)

Perfect as a drop-in replacement for lead-acid batteries, our high-performance copper terminals ensure the best electrical performance while inherently providing corrosion-free contact for those who use eyelet terminals. Two M8 bolts & spring washers are included with the battery.

Need round terminals instead? No problem - we can provide high-quality, hot stamped brass automotive adapters free of charge (just leave us a note at checkout).

Cheaper Long Term

Despite its high initial cost, TITAN lithium is cheaper than its lead-acid counter parts over its lifespan. Our design life is 10 years - rounded up this battery costs £1,800 or £180 a year. The closest capacity equivalent in lead-acid is two Exide AGM EP2100's with a design life of 4 years - currently around £520 each or £260 a year (replacing the batteries at the 4 year mark). This equates to £800 in savings, plus all the benefits of a lighter and more efficient battery.

While the design life of TITAN Lithium is 10 years, we expect the average user to reach 15-20 years, making it an even better investment. The realistic average life of Lead-acid is 3-5 years.

Electrically Efficient

Thanks to our 99% efficiency rating, TITAN batteries utilises incoming charge energy with little waste; making them a perfect partner for solar chargers. Our batteries can accept extremely high charging amps which means they can be charged extremely quickly - from 0% to 95% in less than 2 hours (when charged over 100Amps).

This efficient charging means TITAN batteries are also perfect for home solar storage (although we'd recommend looking at our higher voltage batteries for better BMS efficiency).

TITAN Lifetime Warranty Icon
A Market First - Lifetime Warranty On All Grade A Batteries

At TITAN, we are so confident in our build and component quality, we have upgraded all of our batteries that have grade A cells to our full warranty that lasts the lifetime of the battery. Our parent company celebrated its 75th anniversary of continuous business this year, and we plan to stick around for the foreseeable so you can rest easy that we will be here for any issues that may arise; be it tomorrow, or in 10 or even 30 years.

Important to note: like anything in life, the more you use something, the more it wears out - batteries have always been the same, and their capacity will degrade over time. This reduction is normal and to be expected; the harder you use the battery (i.e. you discharge it fully and charge it fully often), the faster its fully charged capacity will decrease. Lithium has an incredible resiliency to capacity reduction though, and we expect a capacity loss of about 5-10% every decade with normal use and charging within specifications e.g. a brand new 150Ah would have a fully charged capacity of 165Ah, a 10 year old 150Ah would have ~150Ah and a 20 year old 150Ah would have ~135Ah when fully charged.

Battery wear or capacity loss are not valid warranty claims. Once a battery reaches a fully charged point and it does not last very long or last as long as you need it to, you will need to replace the unit.

Our warranty covers all components against premature failures caused by manufacturing faults. For more information on our warranty terms, please click here

Our Batteries are Repairable

If anything does fail prematurely, we aim to repair or replace individual problem components rather than replace the whole battery. Doing this also allows us to reduce our carbon impact and reduce waste. As we are battery specialists (we used to make batteries in the 1950s), we are adept at any and all repairs should they arise - we do ask customers to leave the repairs to us; cells and BMS's are proprietary in design.

The battery will pass the test if there is no mass loss, no leakage, no venting, no disassembly, no rupture and no fire and if the open circuit voltage of each test cell or battery after testing is not less than 90% of its voltage immediately prior to this procedure.

Vibration Test:

PASSED

The battery is firmly secured to the platform of a vibration machine without distorting the cells in such a manner as to faithfully transmit the vibration. The vibration is a sinusoidal wave form with a logarithmic sweep between 7Hz and 200Hz and back to 7Hz traversed in 15 minutes, this cycle is repeated 12 times for a total of 3 hours for each of three mutually perpendicular mounting position of the battery. One of the directions of vibration must be perpendicular to the terminal face.
The logarithmic frequency sweep shall differ for cells and batteries with a gross mass of not more than 12kg (cells and small batteries), and for batteries with a gross mass of more than 12kg (large batteries).
For cells and small batteries: from 7Hz a peak acceleration of 1gn is maintained until 18Hz is reached. The amplitude is then maintained at 0.8mm (1.6mm total excursion) and the frequency increased until a peak acceleration of 8gn occurs (approximately 50Hz). A peak acceleration of 8gn is then maintained until the frequency is increased to 200Hz.
For large batteries: from 7Hz to a peak acceleration of 1gn is maintained until 18Hz is reached. The amplitude is then maintained at 0.8mm (1.6mm total excursion) and the frequency increased until a peak acceleration of 2gn occurs (approximately 25Hz). A peak acceleration of 2gn is then maintained until the frequency is increased to 200Hz.
The battery will pass the test if there is no mass loss, no leakage, no venting, no disassembly, no rupture and no fire and if the open circuit voltage of each test cell or battery after testing is not less than 90% of its voltage immediately prior to this procedure.

Shock Test:
Check / tick mark icon

PASSED

The battery is secured to a testing machine by means of a rigid mount which will support all mounting surfaces of each test battery. The battery is subjected to a halfsine shock of peak acceleration of 150gn and pulse duration of 6 milliseconds. Alternatively, large cells may besubjected to a half-sine shock of peak acceleration of 50gn and pulse duration of 11 milliseconds. Each battery shall be subjected to a half-sine shock of peak acceleration depending on the mass of the battery. The pulse duration shall be 6 milliseconds for small batteries and 11 milliseconds for large batteries.
Each cell or battery shall be subjected to three shocks in the positive direction and to three shocks in the negative direction in each of three mutually perpendicular mounting positions of the cell or battery for a total of 18 shocks.
The battery will pass the test if there is no mass loss, no leakage, no venting, no disassembly, no rupture and no fire and if the open circuit voltage of each test cell or battery after testing is not less than 90% of its voltage immediately prior to this procedure.
