123SmartBMS gen3 is an easy to use yet advanced, modular BMS to keep your lithium batteries in perfect condition, increasing the lifespan of the battery pack.
The BMS measures important data like cell voltages, cell temperatures and in- and outgoing currents with the two included high accuracy, dual range current sensors. By measuring both currents independently, it is possible to know the current production and consumption. The system balances all cells to the same voltage during charging.
Two integrated signal relays with potential free contacts can be used to switch enable/disable signals or power relays to control the power to chargers/solar regulators and/or inverters.
Easily connect your phone to the BMS to see relevant information including state of charge, energy consumed, energy stored, in- and outgoing current, cell voltages, cell temperatures, SOC history of the last week and error history.
New in gen3
LTO compatible, Operates on cell voltages between 1.5V and 5.0V
High accuracy SOC, dual range current sensors to measure a wide range of currents up to 500A.
Error history to see when, what cell and which error occurred.
SOC logging of the last week.
More accurate temperature measurement near cell pole
Over the air firmware update
Modular BMS which can be used from 2 to 255 cells.
Can be mounted directly on the cells, no external controller needed.
Two signal relays with potential free contacts which indicate the system is allowed to load and/or charge. This can be used to switch enable/disable signals or power relays.
Possible to use two current sensors instead of one to see consumed and produced energy independently.
Wireless connection to see relevant data on your portable device.
Compatible with almost any cell chemistry including LTO, LiFePO4, NMC and NCA.
1A balancing current. Even big cell capacities will be balanced.
