| Battery Type | LiFePO4 |
| Voltage | 12.8V |
| Capacity | 243.2±8 Ah(0.2C) |

This LiFePO4 12.8V 243.2Ah is using a lead-acid 12V140Ah battery case, they have a similar size of 483x170x235mm. With 256 pieces of high-quality 26650 cells inside by 4S64P configuration, we are getting this 243.2Ah LiFePO4 battery pack.
Compared to a general-purpose 12.8V 140Ah lead-acid battery, this LiFePO4 12V243.2Ah battery has the same size, but it only has about 60% the weight of the lead-acid battery, 26.5kg. And it delivers us 243.2Ah discharge capacity at 100A current, while the lead-acid 140Ah battery only provides us 85.4Ah discharge capacity at 1 hour rate.
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. Generally speaking, LiFePO4 has 5~10 times the cycle life of the lead-acid battery in the same working condition, it could provide > 5 years’ services life by daily per recharge.
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.
