Review: VALUE - I purchased two of these 12V 100Ah LiFePO₄ batteries and they’ve been absolutely fantastic. The price is almost unbeatable for the performance you get, and the quality has been incredible so far. I run them in parallel to power both an AC unit and an inverter, and they handle the load with ease. They charge quickly, hold power well, and have shown to be very reliable. For anyone looking to upgrade their setup without overspending, these are a must-buy!
Review: Rated high by YouTube’ers - I have 4 of these now and intend on getting more as they go on sale for about $120 each being charged by my 12,000 watt solar panels and Mr Power MPP charger. Set up now in parallel outputting 12-14 volts to a 2000 watt modified sine inverter to power my 2 dead freezers. I have a timer on the 110 volt circuit to power freezers for 12 hours during the day and shut off saving battery storage for 12 hours at night. Freezers can be off for 2 days before showing any signs of defrosting. As I get more batteries I intend to output 24 volts using series/parallel battery connection and powering my 3000 watt pure sign inverter that I used to use 6 golf cart batteries to power. Their life was about 4 years and also were in my golf cart. They used to be $120 each but went to $150 recently so no brainer to go to a 10 yr Lithium battery that’s has more reserve power. The only issue is about the battery management system built into the battery to protect it. It does work as designed but what that means is that when the voltage goes down to 10 volts or so the BMS shuts the battery/batteries down and even if the load is removed they will not charge back up until you wake them up. You do this by applying for a few seconds a 12V DC input from a source like a Jump starter box. So this requires monitoring your system. I put a battery powered no AC alarm I got from desertcart on the inverter output to alert me when this happens. This occurs in cloudy weather. Yes there is a beep from the inverter but not loud enough to here in the house from the garage.

*by J***L on December 13, 2025*

Very affordable good value battery. Installed our camper with new converter. It has a lot of capacity for the money. Only had it in for 2 days will do a follow up during camping season. Overall I like this battery and would recommend. Also bought 2 rack batteries from humsienk and the app works very well for checking battery SOC.
