According to my Victron charger these are genuine 100Ah batteries. It will run my two fridges, one being used as a freezer, for 22 hours before hitting 12 Volts. The voltage drops off quickly at 12.3V, so will set my low voltage shut-off to 12.5V for now.

A great LifePo4 battery for the price. Being used with my electric boat motor & backup battery for my caravan when free camping. Advantages are light weight for the amps available & charges quickly.

On advice from my auto electrician this battery is not holding or accepting charge and subsequently has now gone completely flat twice whilst running a car fridge only.Very disappointing and still trying to sort this out. A lot of money spent for a bad result.
So far this battery has been perfect for the caravan. The only thing that has to be done is to pre charge the inverter if it doesnt have a soft start otherwise the batterys bms will shut down. It charges via a dcdc charger which also has a solar input.
Price was right but model seems too generic to inspire confidence. No data sheet or instructions supplied. After 12 hours charging with 10a lithium specific charger the battery is only at 13.2v (my 4 other 12v lithiums "float" at 13.4 to 13.6v). This one is to be used for the tender trolling motor and backup for the fridge. Time will tell.....
I bought two of these batteries to put in my caravan. So as to run lights, fridge ect. Also wanted to run a 2000 watt inverter. I connected the batteries in parallel so as to have a 12V system that would be able to supply up to 300 amps. The battery specs say they can do 150 amps each so in parallel you get 300 amps. The inverter would only require about 150 amps maximum. Once connected I turned on the inverter with no load on it and immediately the batteries BMS shut the batteries down. Only way I could activate batteries again was to connect a charger. Tried again and next time everything worked as expected. After many more tests batteries would often shut down and other times they wouldnt. Mystified by what was happening I started disconnecting wires from ... MoreI bought two of these batteries to put in my caravan. So as to run lights, fridge ect.

Mystified by what was happening I started disconnecting wires from batteries and in doing so touched the negative terminal to ground and it sparked, which simply should not happen. BUT, when I reconnected the inverter again and did another test it worked perfectly both without a load and also with a 1600 watt load plugged in. So batteries now seem to work as expected but real mystery as to what was happening to begin with. In case people are wondering, yes I am 100% certain I had everything wired correctly from the start.
Fit my old battery box as well as my previous 100ah AGM. It is so light, love that side of it. Would be great if it came with charge Parameters (ie max charge limit, min charge cutoff), and an explanation on what the buttons on the delis play can do. Taking it camping in a couple of days.
Battery fits snugly in my XTM battery box and works a treat. Great service from Sunyee too. Allowing me to pickup in person as I was going camping the following day. Thanks guys!
Hold charge very well, run 25L fridge and never running out of juice for 6 days remote camping. Recharged with 160w fold solar panel from Sunyee too, 3-4 hours from mid-day.Note: used during summertime, December. temperature 25-29 Celsius.
