This harger outputs steady DC 8.4V at 2A times 4 for total 8.4V at 8A (you can charge 4 batteries at the same time conencted to sepearate cables)
Since conector is small and not battery shape depended you can conenct
Mavic Mini 2 battteries to it and charge but only to 8.44V (4.22v per cell) displays 86% of battery
Mavic Mini 2 battery charged with supplied hub shows 8.73V (4.37V and 4.38V per cell) at 100%
MM1 batteries charged in
MM1 charging block and adapter when placed in
MM2 drone show: 100% but 8.38V (4.19V per cell) which is almost per spec (old battery)
You will not break anything, just not fully charge
MM2 battery with
MM1 charger, I can then top it off quickly with supplied charging hub.
You can charge
MM1 in
MM2 hub and
MM2 drone becasue they have over voltage protection built in I belive, they will drop to 8.4V so they are backwards compatible.
for the curious guys 15% of the battery it is about 1500m in normal mode in very low wind conditions, plus 10-12g less weight and we should have ballpark 1600m loger ranage with
MM2
