Wireless data transmission avoids the interference caused by the complicated wiring between the display and the detection module, and the wiring is easier. 2.4G wireless transmission, Hall sensor measuring current, charge and discharge bidirectional current detection Voltage, current, power, temperature, capacity, percentage of remaining capacity, and running time are displayed simultaneously. The Hall sensor is used to realize non-contact current detection without disconnecting the wire, which is safe, reliable and convenient. It has the power-off memory function, and the AH number before the power-off can be memorized after the power-off., Weight: 0.67681914434 Pounds, Manufacturer: Histeaa
