Marces BMS

Marces BMS is the battery management app from MarcES Energy Systems that allows you to read and manage your batteries (12V) and 48V batteries—all in one app, directly via Bluetooth.

KEY FEATURES
- Live data: pack voltage, current, power, state of charge (SOC), and health (SOH).
- Cell voltages: all cells at a glance, with minimum, maximum, and difference between them.
- Temperatures: cell and MOSFET/power temperature.

- Protections and alarms: over- and under-voltage, over- and under-temperature, overcurrent, short circuit, and more—clearly in Dutch.

- Multiple batteries at once: connect multiple batteries and view a combined pack overview (total power, capacity, and average SOC).

- Custom names: give each battery a recognizable name, for example, "Household battery 1".
- Automatically reconnect to your stored batteries. - Management behind an admin PIN: controlling charging/discharging (12V) and setting battery parameters (48V).

FOR WHOM
For owners and installers of home batteries, campers, boats, and off-grid systems who want quick and reliable insight into their batteries.

PRIVACY
The app collects nothing. There is no account and no server; all data remains local on your phone. The app uses Bluetooth (and on older Android versions, location permission) exclusively to find and connect batteries – you are not tracked.

Compatible with batteries that have a Bluetooth BMS based on MarcES
