High performance 12v 230ah LiFePO4 Lithium leisure battery with a BMS that supports Series connection and expansion (up to 51.2V) and also supports Parallel expansion of to two batteries

This is a low profile LiFePO4 battery designed for installation under a campervan swivel seat. This measures (L*W*H) 305*290*190mm


TN Power have used compact cells and a high power BMS, allowing them to us to fit a massive amount of capacity into a smaller case

- 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
- 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.
