We selected this high-capacity LiFePO4 battery 18650-3.2V-1800mAh cell to assemble this battery pack. This provides us a high capacity 12.8V 9Ah Battery Pack, while it only has 7.5Ah capacity previously. And the performance is as amazing as usual, we can maximally use a 25A BMS for the battery pack, and it maximally allows 4 of them in series connection.
This is also a perfect replacement battery for the lead-acid 12V7Ah battery. LiFePO4 has a higher capacity and stronger power within the same physical limitation. And the LiFePO4 cycle life performance is more than 6 times the lead-acid ones.
Although the up-front cost might is higher compared with the Lead Acid one, it saves money and rewards you more convenience in long-term consideration.
