Nice product for the money
Like the device. Balancing feature is awesome. Could do without the very loud beep on every button press however.

Seems to do the job.
I use these on a 20p 4s 32650 lifepo4 battery configuration. I pull at most 50 amps not very often. I don't trust it for a full 100 amps. I do have the charging port wired but very seldom use it. The times I did it took a charge.
I don't use the overcharge protection or undervoltage protection. I have other external devices that manage those functions.
In any event this bms seems to to the ballancing function that I purchased it for.
Good for the price.

Weak
These batteries perform at 1/2 their rating.
Beware they are specified for parts.
