Hooking up battery to charger,plugging into wall outlet,waiting 30 seconds ,unplugging from wall and repeating all this many many many times
hooking up good battery to charger,once it starts charging remove good battery and connect bad battery to charger...really fast.....,the point ist to trick charger into charging bad battery.......i also remember guy using reg.9v battery to restart dead battery but i dont remember how he did it nor do i recommend it
I managed to get drone charger to recognize the battery. First Measured battery at 1.1V, Took my portable 12/6V charger and hooked to battery for several minutes. Voltage raised enough for drone charger to see it. Battery has bben on charge all night with flashing red light.
It was a multipurpose charger, when turning it on and connected to battery it auto recognized it as lithium battery. I monitored the charge voltage hoping battery would get enough residual voltage to work.
Flashing red light indicates the charger is not charging the battery. The voltage is too low for the charger to allow it. First, is the battery packs swollen? if they are DO NOT try to charge them, toss them.
I just opened mine up after recieving it two xmas ago and flew it in my kitchen for 7 seconds. It too had a dead battery that had been left on the drone.
Initially left it 20min no indicator.
Plugged it into drone, one blue flash
Plugged it into charger... red light then blinking after about an hour.
Plugged into drone. 62% - loose prop screws 3 went skyward - oops one screw missing dang.
Recharge battery, it reaches 80% at green.
Flew it 3-4mins down to daughters house, landed in patio, came back. Used 9% or so.
its on charger hoping it wants to push higher than 80%- gonna allow it to charge until ready to capture some neighborhood fireworks or get shot down.
