LED Digital Display: 2 in 1 dual display power + voltage. The upper 8 color bar shows the battery level (2 red and 6 green). The lower voltmeter displays the battery voltage, and the voltmeter's decimal point is automatically shifted with higher precision.
Applicable Batteries: The battery monitor is suitable for 12-60V(12V、24V、36V、48V、60V) lithium battery packs, lead-acid batteries, polymer batteries, NiMH batteries, etc.
Wide Range of Use: This battery voltage meter can be applied to golf carts,car, RV, electric vehicles, self-balancing vehicles, robots and portable devices, etc.
Connection Method: Connect the positive and negative terminals of the display board to the positive and negative terminals of the battery under test, and the nixie tube will display the real-time battery power and voltage (Be careful not to reverse the connection! it will burn if it is reversed).
Waterproof: The back of the battery voltage monitor is fully enclosed, which is more waterproof and safer. Note: Not suitable for large trucks, cranes, forklifts and other high-power and high-load vehicles!
