| Battery Type | LiFePO4 |
| Voltage | 12.8V |
| Capacity | 79.2±3Ah(0.2C) |

This LiFePO4 12.8V 79.2Ah is using a lead-acid 12V55Ah battery case, they have the same size of 228x138x208mm. With 176 pieces of high-quality 18650 cells inside by 4S44P configuration, we are getting this 12.8V79.2Ah LiFePO4 battery pack.
Compared to a general-purpose 12.8V 55Ah lead-acid battery, this LiFePO4 12V79.2Ah battery has the same size, but it only has about 58% the weight of the lead-acid battery, and it delivers us 79.2Ah discharge capacity at 1 hour rate, while the lead-acid 55Ah battery only provides us 33.6Ah at 1-hour rate, or 47Ah at 5 hours rate. If the application continues consuming current is 33.6A, then the LiFePO4 79.2Ah provides 2.35 times the capacity of lead-acid 55Ah.
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. In real usage, the LiFePO4 doesn’t work in 100% DOD, the real working life could be 8 to 10 times
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.
