Update Jan 2023. Its come to my attention that DFUN is on longer selling this battery
The DFUN battery rep has been after me to review their LiFEPO4 battery for a while now. I hesitated since it looked almost exactly like the SOK battery I reviewed a few years ago. I figured it was just a cheap knock-off. But he assured me it was different and used a similar case design.
Because it’s about $100 cheaper than the SOK, I figured it was worth taking him up on the offer to take a look for myself.
*Fair Disclosure* I received complimentary review samples of this DFUN Battery
In this video, I teardown and look at all the components that make up the model DFPA12100 (12.8V 100Ah) DFUN LiFePO4 battery. Then test its charging, discharging rates, low temp protection, and finally, the total capacity. See my Pros and Cons as I see them below.

Pros:
- Low Price Point $480
- 8 Year Warranty
- 4000 Life Cycles to 80% Capacity
- Metal Case & Battery Brackets
- Can Easily Be Fully Disassembled
- Nice Terminal Connections
- Grade A LiFePO4 Cells
- Low-Temperature Protection
Cons:
- Heavy 33 lbs
- BMS – Small Heat Sink
- New Battery to the Market – Not Much Track Record
Overall it looks like a good bang for the buck, but time will tell if the company provides good support and stays around awhile. But, at least if they disappear, the battery is serviceable by a DIY end user.
