How to discharge in series and charge in parallel [solved]

[quote=“Pablo_702, post:38, topic:1589”] This would be a solution especailly if u have a 12s system [/quote]

Has anyone implemented this diagram? Its viable? have any risk balancing the batteries?

man, so simple and clean. this is the best solution for those already have a charger and don´t wanna buy a BMS. and have an option to run in parallel if you need more juice instead power.

but one question: do you protect the balance lead cables?
