16S BMS 60V 30A 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 30A)

This is a great product, I'm new at this, and instructions are good, I like it.. I defff recommend this..

I've purchased 4 of these, all worked.

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). 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.

This product includes a basic manual that lacks information on alternative configuration options for the BMS. Initially intending to build a 16S battery, I later opted to switch to an 8S configuration.Unfortunately, due to the absence of confirmation from the seller regarding compatibility with fewer cells, I won't be able to use this product for my current project.

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.
