Any BMS will do , If anything you would want double redundancy in case stuff go badOn one end.
Because the unity provides batter cutoff , this allows many people to go the charge only route. If you don’t want to have to deal with balancing your battery after a while, get a discharge BMS.
Apologies. So basically you can directly connect a battery to the Unity and it will do everything (accurately manage current draw from the battery if set correctly, Regen, switch the power on and off without any draw when it’s off, act as the anti spark)?
Enertion need to include these basic questions in their FAQ section on their website for noobs like me.
Not sure about idle current draw, maybe it is zero, but some antisparks were known to draw some current even after being “off”, so I’d add a loop key just in case when you go away for a longer time without riding.
You can leave your unity plugged in on a discharged battery for several months without issue. Any charge in the battery extends that to the years time frame where it isn’t worth thinking about.
It handles all anti-sparks functionality onboard.
Quick math: typical 10 Ah battery (4 parallel cells) discharged to 3.1V (unity cutoff) has 10 percent capacity left. 1Ah/0.00001 amps = 11.4 years
