UPDATE!! New battery cells with higher capacity, 1500mAh to be tested today!Hey everyone, I found new battery cells in a camera that fit into the original battery housing but these are 1500mAh and I'm charging them at the moment and I'm going to test the Tello later today to see how long it can fly with bigger capacity cells.
I've tested the 1000mAh battery cell which is new and got about 8 minutes of flight time, the new battery cells are 1500mAh so if I have to guess I might get about 20 minutes of flight time.
But I'll make a video of it, I have 2 of the 1500mAh battery cells and I've got the 1000mAh cell all charged up to be tested later.
I'll make a screen recording of the whole test and upload it to YouTube and I'll come back here and share the link so you can watch and see exactly how much flight time I now have with the new battery cells.
