Re: Safety for Jab alternator

The batteries that I have (EarthX) include a BMS module that will do a hard break if the voltage or current gets out of bounds and also serve to balance the charging per cell. These batteries actually have 2 BMS circuits per battery for redundancy. Nevertheless, I built sealed battery metal boxes vented to the exterior of the aircraft just in case.

If fitting a lithium battery is producing over current issues, I would suggest fitting an appropriate regulator for the battery.
Lead acid batteries are quite resilient and will simply gas if over charged.
Lithium batteries can get nasty if the charge current and maximum voltage are not properly controlled.
Some "replacement" lithium batteries have a built in BMS (battery management system), but I have seen these fail.
The last thing any of us want is a lithium fire.
