The second battery shipment arrived today. Why not buy it all at once? Because I learned that some people don't like to see many samples of the same product being imported at once ... How will the energy be distributed? Final battery configurations have already been determined, but testing will probably also determine the best method.

JP: The motors are designed for 52V (and can pull up to 190A!). This means we should use 14S Lipo, ie 14 cells (each Lipo cell has 3.7V), this way we would have 51.8V. The problem is that there are few 14S batteries on the market (only found on request). Another problem is finding charger for 14S. The solution is to use 2 x 7S in series for each motor. Even so, 7S batteries only have 5000 mAh, which would give very little flying time. The solution to this second problem is not only to put a pair of 7S in series for each motor, but to add one more pair in parallel to each motor in order to reach…

Marcelo... how did you define the proper batteries for your design? And how much do they weigh?
