| Battery Type | LiFePO4 |
| Voltage | 12.8V |
| Capacity | 121.6±4Ah(0.2C) |

This LiFePO4 12.8V 121.6Ah is using a lead-acid 12V80Ah battery case, they have a similar size of 259x167x212mm. With 128 pieces of high-quality 26650 cells inside by 4S32P configuration, we are getting this 12.8V121.6Ah LiFePO4 battery pack.
Compared to a general-purpose 12.8V 80Ah lead-acid battery, this LiFePO4 12V121.6Ah battery has the same size, but it only has about 58% of the weight of the lead-acid battery, 13.1kg. And it delivers us 121.6Ah discharge capacity at 3 hours rate, while the lead-acid 55Ah battery only provides us 67Ah at 3 hour rate, or 74Ah at 5 hours rate. If the application’s continuous consuming current is 23A, then the LiFePO4 121.6Ah provides 1.8 times the capacity of lead-acid 67Ah.
The most deadly advantage is the super-long cycle life, which makes the LiFePO4 win this competition completely. LiFePO4 battery provides us with more than 2000 cycles of life during our lab test under the condition of 1C recharge, 1C discharge, room temperature, 100% DOD, and it still has >80 remaining capacity.
You may say “LiFePO4 is super expensive”, well, I’ll tell you that’s totally wrong. The upfront cost is truly higher, but the long-term cost is definitely times lower because you saved the maintenance and replacement cost.
