I know this sounds like a wasted post since 14s BMS units are everywhere. But I want the smallest footprint possible, but more importantly, I want it to only charge to 4v not 4.2. and cutout at 3. Not 2.7. Usually for adjustable settings like that, the price starts to increase significantly and then size increases as well. And from I understand, Daly BMS units arent that great. I am making a couple battery packs for my Lyric e-scooters and I want to use the existing battery cases and mounts so space is a factor. Thanks
 
maybe check out aliexpress. Of course you'll also find lots of trash there but also cheap and good products
 
None of the small format BMSes I've ever seen are programmable.
 
Normally BMS is not involved in charging.

It's HVC is just a failsafe for when the charge regulation fails, to prevent fires.

Same with the LVC, your controller or you watching the voltage should be stopping discharging long before the extremely low protection setpoint of the BMS.
