Kevin 3 out of 5 stars Good customer support but tricky bms for beginners Reviewed in the United States on 21 December 2025 Verified Purchase Brief content visible, double tap to read full content. Full content visible, double tap to read brief content. Customer support is helpful and responsive. The bms didn’t work for my needs, but if you’re a more advanced user it may be the right fit. I was looking for something more plug and play since it was my first full battery build. — original post — At first, the bms seemed good and the features all worked, but over a couple months they stopped working. The app won’t connect anymore and the over discharge doesn’t protect. I was able to get my 12v battery down to 6v before the discharge device cut off.

DasHaus 1 out of 5 stars BMS works, balance sucks, app is terrible. Reviewed in the United States on 29 May 2024 Verified Purchase Brief content visible, double tap to read full content. Full content visible, double tap to read brief content. I will be returning this BMS. My no-name from Alibaba is far easier to use and configure and the app is much better. Also this BMS doesn't have a separate charge input, so when the unit is 'full' and disconnects the battery, anything connected may be exposed to full charger voltage (solar, battery charger, whatever). The balancing function seems subpar and the app is so confusing/unclear as to what's actually going on that I sought out another unit to try on this pack (110Ahr LiFePO4). The BMS needs to be woken up via a button press on the bluetooth/WiFi module if it has sat for too many hours...which makes me feel like it just tagged on there and not properly integrated. My no-name BMS systems have no such need for a wake intervention (and don't have standby battery draw that is significant). If I had got this for free, I'd probably find a use for it somewhere but having paid money for it, I'll send it back. Also note that the connector for an external UART/RS485 screen is the smaller version and won't connect to the screen's native connector if you have a straight-across cable. I was going to search one out but honestly the 'fuel gauge' in the app is useless anyway. Read more Read less Report Sending feedback… Thank you. We'll investigate in the next few days.
