Manufactured with automotive-grade battery cells, the battery features the highest safety standards and an extended cycle life. Hosting intelligent software, the advanced BMS (Battery Management System) provides comprehensive protection to the battery. The built-in Bluetooth module enables remote monitoring of mobile devices in real-time.
