Greetings first post here.
I want to build a Y harness that will charge and balance two 2s lipos at the same time like if there where a single 4s battery, I have a Triton2 charger and the equinox cell balancer. just want to double check this first just to be safe and don't end up burning up my house.
this is the harness adapter i want to build

this is the original 4s adapter
thanks.
