Post in thread: Portable LiFePO4 battery and inverter. Any improvements?
I put a 12V100Ah LiFePO4 battery and 1500W sine inverter in a box. The box is for a work-van, I need it for charging batteries for power tools, etc. BOM - 12V car plug with usb-c PD 60W - Battery voltmeter for State of Charge(SoC) estimation. (maybe a coulomb counter would be better?) - 1500W...- Reaction score: 1

Post in thread: Using boost converter for charging LiFePO4 from starter battery/alternator
In the work wan(Peugeot Boxer), I have a 12V100Ah LiFePO4 battery box with inverter for charging power tools. I would like to charge the battery box from the inverter. Can I use this DC-DC Boost Converter(constant current) instead of more expensive LiFePO4 dc-dc chargers, like this LiTime 12V...- Reaction score: 0

The inverter have a Ø60mm cooling fan. There is a hole in the box where the fan is located. The battery is from LiTime. They use their own BMS as shown in this teardown. I don't think I'm able to get SoC from it, even though I know the BMS is estimating it. It is a nice idea, I will keep it in...- Reaction score: 0
