DROK Green LCD Display Digital Battery Capacity Tester Indicator - Two Wires 12V/24V/36V/48V Lead Acid Battery Monitor with Protective Shell (DC8-63V) Review

Looks good but no cables. How do I connect this wirelessly! He shows them in photos! Don't buy this counter, spend a few bucks more and get one from a company that really cares so you can use the product you are paying for!

It is connected in parallel with the 12V battery pack and seems to track perfectly showing the percentage. I can only assume it displays correctly since the button on the device doesn't do anything. I'm also assuming that out of the box and with batteries the unit will start automatically with the 12V setting. Salesperson?

Inaccurate. At different loads, the meter will show different power. The product does not allow you to check the correctness of the battery. The instructions are: power off, long press button, power on, select battery type. Not working, held (key button) in the off and on positions for 10, 20, 30 and up to 60 seconds.

Works as described. Setup was easy. Use this on a home build kart with 4 x 12v 12ah batteries (all 48v together). Plugged it in, pushed the button on the back to make it work on 4 batteries and it immediately told me I was 98% charged. The settings are retained even after switching off. It also comes with a bezel pin (haven't installed it yet) but looks like it gives it a nice touch.

Instructions for the many back button settings were not included. I found them in reviews. The low rating is also due to the fact that there isn't an easy way to install this, which is unfortunate as this is a great gauge. Easy to read and see better with green backlight. This guy had made comments in the past about not providing directions. Great product, crappy and or no assembly instructions.
