This battery box can store up to 600Wh of energy and features an inverter to convert the 12V DC from the battery to 220v AC to power home appliances. It also features a USB port on the side for charging a phone and a wireless charger on the top of the case.

The battery is made of 90 18650 cells salvaged from broken laptop batteries. Since not all the cells have the same capacity, the packs need to be balanced. I'm using a 3S BMS for this task.
The battery can be recharged using an off the shelf LiPo charger.

Thanks! I haven't used it for a while but it still works fine.

I might need to check the batteries before putting it under load again.
