Bluetooth BMS Units allow you to monitor your battery from your smartphone, and allow useful features like adjustable voltage and current levels. In addition, ANT BMS have much higher balancing current than a Standard BMS.

If there's ever something wrong with your battery, you can open up the app and find out right there and then.

These are a STRONGLY suggested investment for a nice battery!

Many sizes available! See photos for voltage / current and dimensions
