130 Amps Power Analyzer with High Precision G.T. Power RC Watt Meter

When just reading battery voltage, the numbers are usually slightly different from my good multimeter. The difference has always been consistent and it is not large enough to make the tool worthless. But if you are looking for something to just read your battery's voltage at rest, get something else. However, if you need something to give you consistent inline data, then it is a useful tool.This is one of those tools that I don't use frequently. However, I have used it enough to consider it a worthwhile purchase.

Works as advertised. Funky backlight can be a bit hard to read. Wish it had a momentary switch to reset time counter for usage calcs. Lead wires have an odd insulation and are rather fat so was hard to put  Duratrax Powerpole Connector (10-Piece)  on the ends.

use it to monitor solar charging

A must for any serious RC modeler or for anyone who gives a crap about battery capacity.

Worthless, it was nice when it worked, but it died after just two weeks of using it on my ebike.

Quality power analyzer works as advertised. I use it for my ham radio portable rig.

if your into electronic, you need this device.
