Obtained digital battery tester a month ago.
The attached image is what showed 28 days ago. Followed the "recharge" suggestion from the meter and then retested everything seemed fine.
Drove it out to the field, about 45 minute drive from my house without issue. Visited with friends for 6 hours. Edge wouldn't start, click click click.
Used my jump starter, started up and drove home. During the drive home auto dimming message came on and dimmed my instrument lights. Could hardly read the speedometer.
Next morning voltage on the battery was 12.5 and tester now showed "BAD" not "REPLACE" but "BAD", really! well there was no way I wasn't going to replace it! Did so and reset BMS.
