What you are looking at right now is a lead-acid 12V26Ah size case, 174x165x125mm, we put 84 pieces of CB certificated 18650 cells inside by 4S21 configuration, now we are getting a 12.8V37.8Ah battery pack.
Compared to a general-purpose 12.8V 26Ah lead-acid battery, this LiFePO4 12V37.8Ah battery has the same size, but it only has about 56% of the weight of the lead-acid battery, and it has a 37.8Ah discharge capacity at 1-hour discharge rate, while lead-acid 26Ah battery only provides us 16.3Ah at 1-hour rate.
But those advantage doesn’t make LiFePo4 superior upon Lead-acid battery. The deadly strike is the super-long cycle life, which makes the LiFePO4 win the competition completely.
You may say “LiFePO4 is super expensive”, well, I’ll tell you that’s totally wrong. The upfront cost is truly slightly higher, but the long-term cost is definitely times lower because you saved the maintenance and replacement cost.
