Received quickly. In Odessa in 2 weeks. The BMS board is compact in size. Looks nice and high-quality. Haven't tested it in operation yet, as the batteries are still on the way. Connection is standard. Thank you to the seller!👍🤝

It arrived on time, well packaged, and the product looked good. I didn't get to use it because it wasn't what I needed; I bought it to use with another product, but it didn't fit, so I had to cancel the purchase.

It arrived quickly, well packaged, a very interesting product, but it didn't work for me because my battery is a Life Po4 16s and this product only supports 14s, so I had to cancel the purchase. However, I bought another one that supports 16s and I'm waiting for it to arrive.
