Horrible app
App did work decently last summer. Open it up today and it continually shut down upon opening. Restarted phone, uninstalled and reinstalled app and same issue is happening.
Great app and device
Started crashing recently upon connecting. Will change review to 1 star unless fixed soon! (January 2026)
Very Poor designed app
Problem: When multiple lithium batteries with Bluetooth-enabled BMS are connected in parallel, the system constantly searches for devices, leading to confusion when trying to select a specific battery. This results in connecting to the wrong battery or struggling to access the desired one.
Problem: Firmware updates for the BMS fail regardless of whether the battery is idle state or disconnected.
Problem: Anyone nearby with the same BMS app can connect to your batteries, view their status, or even modify settings (e.g., disconnect the battery). This is a significant security flaw, especially in shared spaces like campsites or marinas, list can go on forever.
The money you pay, for these lithium batteries, you get the cheapest Bluetooth system, Deplorable.
If I can give it a negative star I would

Excelente
Una forma muy efectiva para monitorear las baterías y apagarlas o encenderlas una forma de saber exactamente cuando poder les quedan yo tengo 3 red baterías y las controlo muy bien con esta app me di cuenta que con 2 es suficiente pero estoy contento con ellas
