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: 123SmartBMS at 67% against XiaoXiangElectric's 17%. 123SmartBMS also leads on rating (4.5 vs 2.5). XiaoXiangElectric's advantage is update cadence (fortnightly vs monthly) and ratings volume (147 vs 21). On price, ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
123SmartBMS holds the better App Store score, 4.5 against 2.5. That said, the two scores are not equally well evidenced: XiaoXiangElectric has 147 ratings behind it against 21, so its average is the more settled of the two. Written reviews point the same way: 67% of 123SmartBMS's written reviews are positive against 17% of XiaoXiangElectric's.
123SmartBMS ships an update monthly, XiaoXiangElectric fortnightly. The most recent releases landed on October 24, 2026 and October 22, 2026 respectively.
