Humsienk 12V 320Ah Bluetooth LiFePO4 Battery 4.09kWh Energy for Vanlife & Off-Grid

Awesome batteries

I’ve had 2 of these running for a couple of months on a12 volt solar system and they work great from 24/7 refrigerator to coffee pot vacuum cleaner and any other appliance we’ve plugged in

Battery was delivered fast and at a 59 percent charge which was ideal for my situation as my converter/charger needed to switch to lithium mode. Battery looks very well built and is performing perfectly. Bluetooth works well and I am able to get readings from inside my travel trailer. So far so good!

So far good, been using 3 of them for 2 months and run all my appliances and charge efficiently. Fair price in my opinion. Time will tell everything.
