So I am looking for a cheap BMS for a 18650 LiIon battery I will use for a fan..

The battery is 4S 48P. I looked at the Daly BMS which is only $36. In reading the description I see:

"Over-charge over-discharge protection---18650 Li-ion battery pack will stop charge when its voltage reaches 4.25V and stop discharge when its voltage reaches 2.7V."

Seems a bit high for the high and low for the low, but for the price, what the heck. This is not a critical pack and I think I can choke the high end with the solar charge controller.

If you just have low current just go with what ever ebike bms you can find.

Daly in all its glory but if you dont need high end current.

Thanks. I passed on Daly, as it was going to take a month to get here from China. I just got a cheap ($9) BMS. I am sure it won't show me anything, but this is just a little pad battery for a fan, which should only be needed when the sun is shining bright, so I don't expect it to really do much. I can check the 4 packs for equality myself.
