High performance 12v 100ah LiFePO4 Lithium leisure battery with self heating and a BMS that supports Series connection and expansion (up to 51.2V) and also supports Parallel expansion of to two batteries

This battery is also bluetooth enabled


This has automatic self-heating function that is auto-activated by the BMS when the battery is connected to a charger when the battery temperature is 0C or less. The heating pads are then stop when the temperature reaches 5C, at which point the incoming charge will be used to charge the battery

This is a cylinder cell battery - the benefits of cylinder cells are described below-

Cylindrical lithium batteries, as the name suggests, feature electrodes that are encased in a cylindrical cell that is wound very tightly within a specially designed metal casing. This unique makeup helps to minimize the chances that the electrode material inside will break-up, even under the heaviest of use conditions, where cylindrical cells are less likely to bloat, leak, or rupture, and are more resilient to moisture, heat and vibration.

Cylindrical cells can discharge their energy faster than prismatic cells because they have more connections internally per amp-hour (Ah) and therefore cylindrical cells are used more often in high-performance applications.

Issues like mechanical vibrations, thermal cycling from charging and discharging are all things that can affect a battery's lifespan. Therefore, the design of these cylindrical units is intended to help mitigate risk from these and other factors as much as possible.

In a battery pack composed of cylindrical cells, if one cell is damaged, it will not seriously endanger the entire battery pack. 

The round shape attributes to the mechanic stability of the cylinder cell as it allows for even distribution of electrolytes and internal pressure, greatly reducing the chance of cell deformity and electrolyte leaks.

The Cylindrical cell shape leaves gaps when stacked. This creates space for air to circulate and heat to dissipate allowing the battery to maintain safe parameters and optimal performance in hot temperatures

As you can see from the info above, cell form factor can make a big difference in life expectancy, safety, and budget. Even more so when you are considering a battery for mobile applications such as a Motorhome, Van or Boat. Intense vibrations, bumps, and hot storage compartments such as engine bays are basic conditions a mobile battery must be capable of handling.

This TN battery uses LifePo4 Cylindrical Cells because they provide the best thermal and chemical stability. The LiFePo4 Cylindrical cells are ideal for Motorhomes, Vans and Boats since they provide a constant high-power rating, exceptional cycle life, and superior safety against abusive conditions and extreme operating temperatures. 

- This can be charged using most standard lead-acid chargers, MPPT solar chargers and DC to DC chargers
- These provide significant gains in power density, power delivery and lifetime expectancy
- They offer thousands of charge/discharge cycles
- Light weight - These are about 40-50% lighter than a comparable lead acid battery
- Low temperature charge protection is inbuilt
- They provide 100% depth of discharge (DoD)
- The 100% DOD offers you up to double the useable Ah capacity compared with an equivalent lead-acid battery
- Higher charge acceptance rates allow shorter re-charge times
- These will recharge more quickly from a solar panel than a traditional lead-acid battery
- Maintenance free
- Does not contain any liquids
- Will not sulphate if left discharged - no risk of damage
- No power 'tail-off' - voltage remains relatively constant until almost fully discharged
- Wider temperature operating range
- Onboard Battery Management System and Bluetooth facilities that interact with Andriod and iOS apps 
- The LiFePO4 batteries are the safest type of Lithium battery as they will not overheat, and even if punctured they will not catch fire
- The cathode material in LiFePO4 batteries is not hazardous, and so poses no negative health hazards

- PWM solar controllers are NOT suitable for use with these BMS equipped LiFePO4 batteries
- Your battery can be charged by 99% of all current Lead Acid battery chargers as the charge is controlled by the batteries internal BMS (Battery Management System), However, we advise to use a charger that has either an ‘AGM’ or ‘GEL’ setting, or preferably use a specific Lithium Battery charger which will use the correct profile and charging voltage
- In any fitment where charging is via a dynamo or alternator, it is strongly advised to fit a DCDC charger to control voltage. In systems that use a ‘Smart Alternator’ or where the voltage is above 15v for a 12v system or multiple’s thereafter for series banks, a DC-DC charger MUST be fitted to avoid the BMS shutting down to protect the battery.
- The App is available for all Apple and Android devices
- The App will give you visibility of your battery and its performance. The App works via Bluetooth so you need to be within 10m of the battery to access it.
