I created this PCB for my personal project of a very big custom Li-Ion Battery which i use to charge my FPV Racing Drones Batteries on the flying field. With this PCB, you can build your own LiIon/LiPo Battery with up to 6 cells. You dont need to worry about the balancing wires, they are intregated in the PCB.

An ISDT BC-8S monitors all your cells and alerts you if there is any problem.

In adition, i also added 3 USB QC3.O USB Charging Ports, which can be seperatly turned on/off via a pin header jumper.


  • connect up to 6 1S cells via XT60
  • XT60 Plugs (direct or via cable)
  • 3X 24W USB QC3.O USB Stepdown
  • Balancer Port
  • Port for ISDT BC-8S
  • open copper trace on back - fill with solder tin to increase trace height
  • 99mm x 80mm Board (all dimensions here)

Important Notice

I removed the solder mask in order to apply solder to the traces on the back. I highly recommend to add a good amount of solder to all traces on the back to increase the trace height. With this method, the Traces can withand high amp flow.

I highly suggest to charge big parallel packs with individual 1S Chargers. Charging big batteries via the Balancer Port may take a while.

If you want to use less than 6 cells, just bride the unused XT60 ports.
