ToolkitRC MC8 Multi-Functional 2-8S Battery Checker

Cool but..,

Great lipo checker, no provisions for different battery types. Lots of functions quad pilots won’t use like the servo stuff. Quality build, screen is not very bright sun friendly. Because it only checks lipo’s and it’s hard to see in the sun, not worth $30.

Small, colorful, functional.

This battery checker offers the most selection of features in such a small form factor. Features like a signal generator to test servos and ESCs on the spot make this checker an essential tool for any FPV pilot.

Make sure you calibrate

I like being able to see all my cell voltages at once and the device boots quickish (I'd prefer faster!). The problem is that the voltage was off by over 0.1V compared to my expensive brand multimeter and the $8 cheapie this is replacing. How can the device that costs 4x as much fail at doing the one major thing it is supposed to do? It can be calibrated by holding the wheel down when powering it though. I'd also prefer if the balance lead input faced up, like every other device I have, and if the PWM output function remembered what mode it was left in. Too many clicks to get a servo centered when you need to even do long clicks to get it into "center" mode.
