Using LFP prismatic cells: advanced stacking production technology, the battery loses very little water, which significantly prolongs the service life of the battery in high-temperature environments;

High assembly pressure design structure: During the deep cycle charging and discharging process of the battery, the life attenuation caused by the expansion and shedding of the positive plate is slowed down so that the battery life is longer;

Adopt lithium yttrium patented technology: make the battery charging acceptance better, capture the instantaneous current fed back by the vehicle faster, even if the battery discharge depth exceeds the design depth, it can also ensure the rapid recovery of electric energy, avoiding the adverse impact of over-discharge on battery life;

Ultra-long starting life: The number of starting times can reach up to 200,000 times, and the life span is more than three times that of lead-acid batteries of the exact specification.

About charging

The battery’s nominal Voltage is 12 V, and the operational Voltage is 11.5 V – 15 V.
The maximum charging voltage for the initial charge is 15 V.
Recommended subsequent charging is 14.6 V.
The minimum Voltage is 11 V.
Maximum discharge current is 3C continuously.
Operating temperature -25°C up to 80°C

The manufacturer precharged the batteries to a conservation charge (usually 30-50%).
To be able to use it must first be charged with a low current.
The first charge should not exceed 0.5 C; e.g. for example, a 40Ah battery is 20A.


These batteries are suitable for all starting internal combustion engines. Principles do not require any special electronics for the use of 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.

There is no Self-discharging effect.
Can be recharged at any state of discharge – no memory effect
LiFePO4 is a very safe technology, does not have spontaneous combustion, and does not react with moisture or oxygen.

The monolithic 12V batteries do not have any PCM (any electronics) inside. They consist of finely balanced cells with identical performance. The battery must be managed and operated as a single monolithic 12V block. We do not recommend operation in serial connection. For systems with higher voltages, 24/36/48V and more, we recommend using single cells 50ah+BMS
