The main concern is the over discharge detection.
It is adjustable at the factory but 2.8v is the default unless the buyer requests a different value.
2.8 is ok for Li-ion but it’s too low for Lipos.
Both chemistries have the same full voltage if 4.2v
The difference is the min safe voltage.
Li-ions can go a lot lower than Lipos
I would not recommended taking Lipo’s below 3.4v
If the bms is set for Li-ions at 2.8v cutoff,
It can still be used for Lipos but it will not protect the cells against over discharge
With the lipos, the charging is more important right? (As far as balancing goes)
He is huge in to drone racing so he knows battery safety, I’ll just have to make him aware of over discharging his batteries. I’ve been trying to convince him to get 18650s but apparently he knows people that work for turnigy and may be able to get a better deal through them.
If he does, I told him to bring it to the forum and hook everyone up!
If he run a vesc based controller he could set there the battery cut off to 3.4-3.5v.
With it the vesc cut off before the bms cut off would start. Safe the lipos from over discharge too
No need to bypass with an 80a bms and low voltage soft back off strategy of the Vesc
Set the Vesc low voltage start at 36v
And low voltage end at 34v
And you’ll be good to go
