In this video, I demo and give my take on a new battery monitor series KH-F from Junctek. My main interest in the latest version is the low-temperature protection functionality. A big plus for people using lithium batteries in the cold. So a good portion of the video is testing that specific feature.
Other welcome updates include a plastic case for the shunt and revamped graphics for the display and app. Overall not a bad battery monitor for the price. For me, the cons are flimsy wiring and connectors and not very sophisticated tracking of the battery capacity. Frequent full charge cycles would be required to keep an accurate percent charged figure.
