You won’t be able to use these unless you have a 26 pin plug for them to connect to. This is because these charger need the two wires to connect to each cell but bms’ and balance charger only have one wire in between each cell so unless you can find a way to connect it up like that this won’t work. And even then in my head it feels like the whole thing would short out because the positive of one little board would need to be connected to the negative of another since your cells are connected together. BUT FOR SCIENCE…
Edit: That sounded a lot simpler in my head lol
