GWL/Power Lithium Battery LiFePO4 (12V/20Ah)
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.
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.
FAQ: Initial charging information
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
Check recommended accessories:
the terminal covers for the 12V batteries.
They protect the terminals against dirt, damage and short-circuit.
