## What is 123SmartBMS?

123\SmartBMS 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 system measures important data like cell voltages, cell temperatures and in- and outgoing currents. It also balances all cells to the same voltage during charging.

The BMS supervises the whole battery pack and has two signal relays to indicate “allow to charge” and “allow to discharge”. These signal relays can control chargers and inverters with “enable”/”disable” signals or by connecting an energy efficient power relay to the signal relay. An example is the 123\SmartRelay.

Easily connect your phone to the BMS using Bluetooth to see relevant information including state of charge, energy consumed, energy stored, in- and outgoing current, cell voltages and temperatures.

With 123\SmartBMS, your battery pack is in safe hands.

## Key features

- Monitors cell voltages and temperatures
- Tracks in- and outgoing currents
- Balances cells during charging
- Bluetooth connectivity for real-time data
- Controls charge/discharge signals
- Extends battery pack lifespan

### 1/5 — Nothing

*2022-01-19*

Won’t even find the bms
Other apps do so don’t know the problem

### 5/5 — Great app

what does the u.s. iTunes app store have against system optimizer apps, system memory refreshing apps, & battery boosting apps? 
seriously! 
every time i find one that does it all, inevitably the app store phases it out. 
these types of utilities are readily available in every other store, but not in the u.s. store.
it's as though apple doesn't want it's customers to be able to enjoy the benefits of this type of utility, and they don't have the right to decide that for their customers.
(and yet they have done just that)
hasn't anyone out there noticed this? 
i cannot be the only person.
