Charging battery while still connected to light?

I have two of these MagicShine knock-offs . I’m going to be running them off of a 2s LifePo pack, not the stock li-ion pack. I want to wire up a balanced charging connector that I can simply plug into the charger without having to disconnect the lights, such that the lights and the charger will both be connected to the battery at the same time, while it’s charging. Will this work?

Assuming you wire up the balancing cable and have the correct settings on the charger, yes.

Awesome, thanks. I’d only realized this after I’d begun wiring things up, and I hoped it wouldn’t derail my design.
