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.

Verdict
The clearest difference is review sentiment: Worthless Controls at 100% against 123SmartBMS's 67%. Worthless Controls also leads on update cadence (every 3 days vs monthly). 123SmartBMS's advantage is monetization model (free vs free with in-app purchases) and rating (4.5 vs 4.3). On price, ads, in-app purchases and device support there is nothing between them.
