Hey fellas, both of you will probably be ok, given the DJI charger SHOULD do its thing and only charge a safe temp battery.
What bothers me about the DJI system, is say you finish flying, and want to put it on straight away as per pommy's post below . . .
Now not sure of battery charge temp range on the
MA /
MA2S, but as per my M1P battery info, the safe charging temp is between 5c and 40c.
So say the battery comes out hotter than safe charge level from being used in the sun, flying harder etc, and you pop it in the charger and assuming it doesn't start charging immediately, but will just come on when it's in safe range.
What bothers me in that regard is will it start charging at 40c or 39c ??
And then gradually come down as it charges hopefully.
To me if that happens, it might be detrimental to the longevity of the battery(ies) charged this way, even at what DJI says is safe . . . safe for lipo fire, what about battery life ? (Do they really care ? $$$)
I have to say having 6 and 5 batteries respectively for the M1P and Spark, I rarely have to charge anything before well and truly home, that is if I have flown any below say 40% - 50% and want to fly again soon.
Otherwise I just top off to 2 solid / 3rd flashing leds and take them off.
pommy, keep in mind those Stihl power tools are wicked powerful, and I think the batteries need that special cooling charger.
I had a Blue Gum (huge, 3 tonnes of firewood) taken out by an expert crew last week . . . down to 8" to 10" dia they were using battery Stihl chainsaws, fast (maybe faster) than my 45cm bar petrol unit.
