## Customer Reviews

### ⭐⭐⭐⭐⭐ Decent BMS
*by N***H on February 8, 2024*

I did a bunch of research on the BM3451 BMS chip that is used on this board and knew I needed the TNDC/SMDC variant to work with 18650 LiPo batteries per the datasheet. Another reviewer had noted that they received the BHDC variant for 3.2v LiFePo batteries but the product descriptions says these ones work with 3.7v LiPos. For 14.99 I was willing to find out so I ordered a set of 3s boards. I was excited to see that the boards that were sent to me were the TNDC variant. After a little bit of testing on a simple 3s1p 18650 pack, I found that the over-charge, over-discharge, and balancing capabilities of this board all align with the datasheet for the BM3451 chip. Additionally, I was very happy to see that my board was not covered in any sort of clear silicone or paint like some others have mentioned in their reviews. Overall I'm very happy with this inexpensive BMS board. It works as advertised and can be modified for use with 4s or 5s packs through minor modifications to the PCB (See the BM3451 datasheet).

### ⭐ No Schematics
*by A***N on September 9, 2025*

Poor construction and without an included schematic you're left searching for similar boards online on how to connect to your battery pack. It could have been a 5 star rating if it didn't fry one of the chips while under a moderate load. No where near the 100A claim. Maybe you can figure it out but as a hobbyist I managed only to waste money and remove the magic smoke from it. I may have more luck from the second board I bought, but would not buy again.

### ⭐⭐⭐⭐ Works great so far, fits in a powertool battery
*by T***M on November 15, 2021*

Just wish it came with some documentation/wiring diagram.Built in balancing as well.
