for 6V-48V lead acid battery
Dimension: 42*21*11mm
This battery fuel gauge, is to measure battery terminal voltage and compare it with settings of voltage-capacity relation table built-in micro-processor, as work principle. Even for the same battery, discharging curve is different at high or low discharging current, so the measuring result is rough, which is 10%-20% tolerance.
