If you are just after charge only
Cheapest balance charger works fine.
Just use a charger don’t worry about a bms I only balance charge and. I’m still alive.
If your worried about your pack catching fire do search and see how many have caught alight here :), bms are great but have a few disadvantages.
I’d be worried if was travelling in a Plane that didn’t have a bms in its battery pack, but on a skateboard no worries just as long as the cells are new made well and ventilated.
