Compatibility
- Batteries the maker says it charges
- Lithium equipment only, and never a lead-acid equalisation mode
“Charge only with compatible LiFePO4 equipment. Do not use lead-acid equalization modes. Stop operation if abnormal heat, odor, swelling, damage, or repeated BMS disconnects occur.”

Other findings
- App monitors one battery only
- The app reads one battery, not a bank
- Communication ports
- Bluetooth, CAN bus and RS485
- Document describes itself as condensed
- The sheet says of itself that it is condensed
- Low capacity alarm threshold
- An audible alarm at 10% remaining
- Low voltage disconnect
- Cuts off at 10 V, reconnects at 12 V
- Self heating workflow
- The BMS blocks the charge, warms the cells, then lets it through
- Series configuration affects heating
- Wiring in series may stop the heater working
“A: The app is deigned for single battery usage. The app will see updates which may expand upon this capability in the future. We have a hardware solution in development which is designed to work around this limitation.”
