Common Questions Before You Buy

Does it auto detect battery voltage?
Yes. Connect to any 12V, 24V, 48V, or 72V battery system within the 8V to 100V range and the indicator displays the correct capacity reading automatically.
Which screen color should I pick?
Blue Screen has good night visibility, easy on eyes. White Screen reads best in daylight. Color Screen displays multiple colors and is the most visually interesting.
How accurate is it?
1% accuracy with measurements twice per second. Suitable for monitoring battery state on RVs, e bikes, and solar storage. Not for laboratory grade precision.
Is it waterproof?
No. The indicator is not waterproof and should be installed in a protected location away from direct water. Wipe the screen with a soft dry cloth when needed and avoid exposure to heavy moisture or rain.
Will it drain my battery?
Minimal draw, less than 15 mA. Safe to leave connected long term without affecting battery life. Wire it through an ignition switched circuit if you want it off when the engine stops.
