The M7 multi functional balance charger from Toolkit RC takes everything we love from the previous generation M6, to gives you 33% more power, along with several other improvements such as a simplified interface and a better display that can be used outdoors more easily. We have found that out of the box (or after a firmware update) you will likely need to calibrate the voltage on the charger before use, it takes 3 minutes but you will need a voltmeter. We have a quick guide showing how to do that here - Toolkit RC voltage calibration guide.
