After doing a lot of research, I've come to the conclusions that given the Core UDC-20 charger and balancing harness it comes with:
The Core charger and the harness connector that plugs INTO the charger are
JST-XH.
The Core 5000 lipo battery balancing connector and the harness connector that plugs INTO the battery are
JST-EH
I was thinking, if all the plugs are
JST-EH, then why can't you plug the battery into the charger directly without the harness the UDC-20 comes with? (You can kinda jam it in there, but it's not a perfect, direct fit)
Am I right?
