Crazy battery issues with Boxer DNA75C Squonk

[Flyingdutchman]

I just got a Boxer DNA75C Squonk that takes (1) 20700/21700 battery. I purchased 2 Keeppower 20700 batts from Illumn. They get good ratings from Mooch so I went with them. When I charge them on my Xtar VP2, they charge to 4.20 and the mod reads them at 98%. That’s fine. It’s when use the mod, the battery levels are all over the place. They go from 98 to 84 then up to 86. When they get below 60%, that’s when the battery meter gets really wonky. It will drop to 34% and then 13%, then up to 30%. It’s quite frustrating. All firmware is up to date. I vape at 50 watts on a .3 single coil setup. I purposely paid a premium to get a DNA chip and I feel like it is very problematic. Also, the clock always goes back to 12:00 when I change the battery but my wattage settings stay where they were before the battery swap. Hopefully this is a firmware issue that will be addressed. Working outside all day without being able to charge, is making this mod a bit useless.

Sounds like a battery or ground connection issue causing the board to see too much battery sag, sorry I don't have the mod to give you more specific advise.
