The monolithic 12V batteries do not have any PCM (any electronics) inside. They consist of finely balanced cells with identical perfomace. The battery must be managed as a single monolithic 12V block. We do not recommend operation in serial connection. For system with higher voltage 24/36/48V and more, we recommend to use Winston Single cells + BMS123Smart
Nominal voltage of the battery is 12 V and the operational voltage is 11,5 V - 14,8 V.
The maximum charging voltage for initial charge is 15 V.
Recommended subsequent charging is to 14,8 V.
The minimum voltage is 11 V.
Maximum discharge current is 3C continously.
Operating temperature -20°C up to 65°C (discharging)
These batteries are suitable for all traction applications including electric vehicles. Fully complies also for stationary applications - such as energy storage.
Also possible to use for starting internal combustion engines. In the Principles do not require any special electronics for use LP 12V batteries for starting, but it is very important to keep min. and max. voltage, so we recommend using any voltage indication unit, which you will be informed about the current Voltage. This is important especially for frequent starting. We recomend use some simple car Voltmeter.
We offer a indication voltmeter PROM-VOLT
There is no Selfdischarging effect.
Can be recharged at any state of discharge - no memory effect
LiFePO4 is a very safe technology, not spontaneous combustion, does not react with moisture or with oxygen.

NOTE! All goods we supply is new direct from the manufacturer.
The batteries are charged conservation.
To be able to use it must first be charged with a low current.
The first charge should not exceed 0.5 C - eg for 20Ah battery is 10A.
HINT! For initial charging multiple batteries, must be connected in parallel and the charger outputs should be connected to both ends of the parallel rows of batteries, exactly as it is described here:
FAQ: The initial charging of the number of batteries
LifePO4 charger 12V
Universal charger for LiFePO4 cells and batteries. Can be used to charge four cells in series (4S) or charge the 12V battery with PCM or LiFeYPO4 12V battery.
For this capacity, we recommended 12V 5A charger .
Battery protect
The BatteryProtect disconnects the battery from non essential loads before it is completely discharged (which would damage the battery) or before it has insufficient power left to crank the engine.
The BatteryProtect is not designed for reverse currents from charging sources
| The battery packing does not contain any accessories. For fixing terminal connectors, please, use screws with standard thread of ⌀ 4 mm. |
