Compact module for quick battery level indication, configurable for 1S-8S packs by selecting the desired pad. LED display in 25% steps with red LED for low level, operates at 3-34VDC with typical error of 2%, suitable for Li-Ion assemblies and also usable with NiMH within voltage limits. Dimensions 43.5 x 20mm.

Panel module for quick monitoring of lead-acid batteries, displays voltage and charge level via color LED bar. Automatically detects 12-60V systems, provides stable reading with approximately 1% error and fast update at 300 ms. Easily mounts in cutout, has low consumption 5-15 mA and red zone for signaling discharge.

Quickly monitor the status of 1S-8S lithium battery packs, display the voltage on each cell or total and warn you with a buzzer when discharging. The low voltage threshold is adjustable from the button, and below 3.3V the LEDs flash and the alarm sounds. Works with Li-Po, Li-Ion and Li-Fe, is powered directly from the battery and measures up to 36V.
