To add to that...
Open air battery bays and ventilation holes in the charger body MAY be a bit of over compensation.
But it's a safety net, I'd highly prefer to keep functional.
All lipo sacs are not created equal. Some don't breath at all making them even more of an increase in potential risk. Some burst open during an event exposing whatever is nearby to the volatile flames they're supposed to contain making them completely useless.
A false
sense of security.
I'd much prefer we rely on the safety nets in place then tirelessly and fruitlessly be forced to lecture the community on what makes for even a useful lipo sac, let alone a good one.
