So I got a quote from BesTech this BMS. 53 dollars per bms. It is li-ion 8s 60 amp with an e-switch! The minimum order is 2 BMSs so I need another person. My plan is to buy both BMSs and to have someone buy the extra BMS off me for 53 plus shipping. Just want to ensure that I have a buyer for one BMS when I get both of them. Plan to ask them for an overcharge protection of 4.2 v and an over discharge protection of 3 v. US only.
Here is the bms specs.
