BBX1‑8S is a precision balanced voltage indicator, compatible with most popular battery types: LiPo, Li-ion, Li-Fe, Li-Mn, etc. Connects directly to the battery balancing connector and allows you to instantly see the voltage on each cell individually and the total battery voltage in the range of 3.7-30V.
The device supports from 1 to 8S, and has a high accuracy of measurements — ±0.01 V. Ideal for daily monitoring of batteries, as well as to prevent excessive discharge in the field.
The sound alarm activation threshold is set separately: from 2.7 up to 3.8V in steps of 0.1V. This allows you to set a critical level for any usage scenario. The alarm is loud — it's easy to hear even in an open area. If necessary, it can be turned off completely.
The BBX1‑8S is powered by the first battery cell, therefore, the voltage on the first channel should not be lower 3.7 IN. Compact body (41×26×13 mm) made of hard plastic protects the board from accidental impacts. Weight is less 9 G, therefore, the device does not interfere even in a small backpack or pocket.
