| Chemistry | LiFePO4 |
| Voltage | 12.8V |
| Capacity | 1800mAh (@0.5C discharge) |
| Energy | 23.04Wh |
| Dimension | 97(L)x43(W)x52(H)mm |
| Weight | Approx.240g |
This 12.8V 1.8Ah battery pack is assembled by 4 pieces of LiFepO4 high-capacity 18650-3.2V-1800mAh cells in 4S2P configuration, it’s the smallest one in our lead-acid replacement product series.
The battery enclosure size is 97x43x52mm, the weight is only 240g. This small size is unique because neither 26650 nor 32700 won’t provide you with such a dimension, and the 14500 cell won’t provide such an excellent performance.
If you think the size is unnecessary and only would like a heat-shrinking battery, that’s perfectly fine for us.
Or if you want more energy in this tiny case, we can also provide a lithium-ion NCM 14.4V 3Ah battery pack for the same.
