I created last year this PCB for parallel charging LiPo / LiIo Batteries. My goal was too have a little bit of extra safety when i charge parallel.
- XT60 / XT30 are fused with 15A fuses.
- Balancer fused with self resetable SMD fuses.
I can recommend JLCPCB.com to order the PCB.
- 1.6mm thick PCB
- 5pcs / ~5€ incl. shipping to Europe
I ordered the parts from LCSC.com. I have added the BOM, this can be imported directly into the LCSC.com BOM Tool.
Check the guidelines for parallel charging and plug the XT60/XT30 first
