Description

It’s amazing that we filled a LiFePO4 12.8V 30.4Ah battery in this lead-acid 12.8V18Ah size battery case. This battery is widely used for many different applications, for scooters for golf trolleys, UPS and etc. We can also provide the extension cables such as T-Bar connector to connect your device easily.

We used 32 pieces of UL certificated 26650 battery cells in a 4S8P configuration.
Compared to a 12.8V 18Ah lead-acid battery, this LiFePO4 12V battery has the same size, but it’s 63% the weight of the lead-acid battery, and it has a 30.4Ah discharge capacity at 1-hour discharge rate, while lead-acid 18Ah battery only provides us 11.8Ah at the same discharge rate.

But those advantage doesn’t make LiFePo4 superior upon Lead-acid battery. The deadly strike is the super-long cycle life, which makes the LiFePO4 win the competition completely.

You may say “LiFePO4 is super expensive”, well, I’ll tell you that’s totally wrong. The upfront cost is truly slightly higher, but the long-term cost is definitely times lower because you saved the maintenance and replacement cost. What’s more, the price of a small-size battery is totally acceptable.

Most of the suppliers are not able to provide such a high energy density solution for this size.
But we invested in the plastic case and BMS development only for this case. We’ve optimized all possible factors, we’ve even optimized the packages method to guarantee the service quality.
