And if you want more, you can use 4 cells connected in a 2s2p arrangement. The only problem is these are 900 mAh, far less than the 18650s, but still enough for a long flying session (more than 5 h at 170 mA). Also, as Xjet said, 4 buttons chinese chargers (like this or this) are appropriate for these cells used in the LiIon setting.Īs they have the same size as AAs, you only have to drop 2 of these in the battery bay, and install a jumper (cable) through unused compartments (see attached image). There are also specific chargers like this one, or some of these. this one and this one) and unprotected versions ( this one) of 14500s. this one at HK) that fits in the 120*50*15 battery bay, but a simple and 'elegant' solution would be using 14500 LiIon cells (e.g same dimensions as AAs), instead of 18650s.Īs with 18650s, there are protected (e.g. I think a better solution would be using a flat LiIon pack (e.g. This compartment is 15 mm deep, so maybe removing it would give the extra 3 mm needed, but that would be 'major surgery'. As you can see in these photos, the main pcb is just behind the battery compartment. I'm afraid it would be difficult to fit 18650 batteries in Flysky's 4 & 6 ch systems (BTW, 18650 means diameter = 18 mm and length = 65 mm).
