Why I use BMS for discharge only?

There are some benefits on wiring a charge/discharge BMS mainly to protect the cells of overcharge and overdischarge, however this also has a really big disadvantage as you might loose brakes during an emergency braking if you battery is fully charged. For me life is way more important than taking care of cells health, this is why I build all my battery packs with BMS for charge only.
