  • Smart Usage: Equipped with a mobile app for quick connection and remote monitoring of single or multiple battery statuses (voltage, current, capacity), it supports CAN/RS232/RS485 communication protocols for seamless compatibility with all-in-one inverter chargers, and features a built-in indicator for convenient local status checks.

  • Good product, bad service
Style: 51.2V100AH (Bluetooth)*1
Works as advertised. Horrible customer service with it being a Chinese distributor unfortunately. I had a charging issue with one of two I have in a bank, and they just wouldn’t respond to resolve the issue. Thankfully Amazon backed me with the A-Z guarantee and I was able to get a refund to get a replacement. Just communicate with your customers! Thank you Amazon ... show more

Style: 51.2V100AH (Bluetooth)*1
So far so good. Great for solar battery backup. Please give more details on connecting from battery to battery communication. Please provide number of cycles life of battery on app. Please provide a hub that will allow to see all batteries connected at once in app.
