Great bit of kit and awesome price for what it does. Easy to install (though I changed my mind and moved it and remounted it and....). Looks really clean and professional flush mounted in my home built, carpeted battery box (I would do pics but not quite finished the install). Excellent sales service too, arrived in record time.

FAQs
12V, 24V, 36V and 48V DC systems, with a voltage display range of 8V to 100V.
Yes - the Ah capacity must be set during initial installation as the monitor doesn't auto-detect it. It's also recommended to calibrate 0% (battery fully discharged) and 100% (battery fully charged) so the percentage reading is accurate.
The display shows the net current - charge current minus load.
It should be installed by a competent person familiar with DC electrical systems. Always disconnect the battery before wiring and fit an appropriately rated fuse close to the battery positive.
Press the SET button - this mutes the audible alarm and returns the monitor to normal operation.
Surface mount using the supplied bracket, or flush mount via a Ø55 mm hole cut in the mounting surface.
