That would be an excellent alternative in terms of power and voltage (and discharge C values), but if you transform this 4S battery, in 2 batteries 2S, I see some difficulties here :
- As you mentioned, the width would be wider (34 mm instead of 30 mm for the original ones.
- The overall thickness, would be a little too much (33 mm /2 = 16,5 mm instead of 10 mm for the original ones)
- The weight could be not the ‘most appropriate’ : 155g / 2 = 77,5g - 2,5g XT60U connector - 2g JST XH - 1g wires = 71g for this 2S setting, where the original one is 45g only...
The length would be Ok as it is 70 mm for this cell Vs 72 mm for the original one.
The increase in thickness and width on all the length of this graphene battery seems to be the reason of the important increase in weight.
I am under the impression Parrot did a hard job to integrate the best weight and dimension in the Anafi to get the best balance and obtain an optimal flight time.
I’m still trying to find a reliable source for the original cells (despite a philosopher’s ‘accept your fate’ sentence ;o)
