16S BMS 60V 100A Li-ion PCB Protection Board with Balance Wire and NTC,Ten Functional protections, Common Port, for Solar Energy Storage, Balance Car Lithium-ion Battery Pack (16S 60V 100A)

Product good, just found out it was something different

Item is described great fast shipping

Manufacturer should be removed from Amazon. 48 cells Checked for fluctuation (unstableness), individually charged (4.1v). Assembled (Spot-weld pairs of 3p), then 16s (Spot-weld) two negative battery lines to negative battery port. Negative Charge and Negative load connected to C-. Again to no avail (second 30A purchase) Description from sell always blur and claim it can do Lithium ion AND Lipo4. (But not identified as (Smart). Item IS ONLY LIPO4. Protections are either over done. Claim it's Common Port C-, (30A has P- port, but "not used", but at full charge just cuts off using C- port. Counting on you to give up disassembling just for further lengthy return.

I needed a BMS to provide 60V for a mower project. I have about 70% of the batteries needed for the project but several failed so the project for this BMS is on hold. However, the BMS seems well built. It came with a small manual but setup is typical of most BMS of this type. I like the fact there is more heat sink area on top to dissipate the heat and a thermal sensor for pack overheat warning. The BMS comes with larger wiring that can handle the higher amps, which is a plus. Once I have a set of matched cells I can update this on the final build and how it works with charging and maintaining the pack.

excellent purchase
