TC147 1.47 Inch Electric Wheelchair Battery Monitor Battery Management System Color Screen 8-80V 0-150A

Equipped with a color TFT dot-matrix screen, it allows users to quickly access key information such as remaining battery level, voltage, and current. The adjustable multi-level backlight ensures clear readability in both bright and dim lighting conditions. With flexible installation options—embedded into the battery surface or mounted on handles/control panels for easy access—it significantly enhances usability.

The high-precision shunt (accuracy up to ±1%) continuously tracks charging and discharging status, providing estimates of remaining usable time and battery level. Equipped with a low-capacity alarm function, this helps users schedule timely charging/discharging, preventing damage from overcharging or over-discharging.

Compact and lightweight, the device is ideal for weight- and space-sensitive applications. With a wide operating voltage range (8-80V), it is compatible with mainstream wheelchair batteries. The low-power design avoids impacting battery endurance, while the membrane button version offers splash resistance and light rain protection, ensuring durability in medical or outdoor environments where accidental liquid exposure may occur.
