Any problems using this with 21700s?

Hi, 21700 battery pack and 18650 battery pack have the same 3.7V voltage, this DALY BMS PCB protection board can protect 18650 li-ion lithium cell battery pack as well as 21700 battery pack, no problems. Thank you and best regards

Made 2 seperate packs, but the bms does not seem to work when paralleled together. Is this normal? A fix?

You should have two bms for two packs
