I use this for charging in the shop:
Fstop Labs
Mavic 2 Battery Charger, Accessories for DJI
Mavic 2 Pro Zoom, 5 in 1 Rapid Parallel Battery Charging Hub Station, 3 Batteries, 2 USB Ports, with Power On Off Switch
https://www.amazon.com/dp/B07GYNZ4QT/ref=cm_sw_r_cp_tai_8G4QDbHC2YFPV
It’s a parallel charger, so up to 3 batteries can be charged simultaneously. If memory serves 3 batteries starting at 10-15% are fully charged in 85 minutes (approximately).
NEVER had a problem with this unit...and I have ones from the same manufacturer for the Mavic Pro 1 and Spark birds.
BTW, I use this on my
Mavic 2 Enterprise (Zoom); only difference between your batteries and mine is the Enterprise ones are self-heating for cold(er) environments.
NOTE: contrary to some of the reviews on this charger, mine WAS properly grounded. I also monitored the temperature of the charger and batteries with an IR gun and everything was fine.
I also like the fact that the battery pigtails have captive dust caps to keep the pins clean.
As always when charging batteries do so in a safe place, and monitor them REGARDLESS who made the battery and charger.
