The battery (3.7v), of course, has 2 wires, red and black.
The charger also has 2, white and green. I understand these are data wires with white as positive and green as negative. Will it be safe to splice a connector to the charger? i.e: white to red and black to green?
I took a chance and tried it anyway. You were bang on the money. It didn’t. I charged for an hour and then not a peep out of the battery. (But I suppose there is the possibility that it might be a naffed battery?
What I am a bit perplexed about is: the charger lead only had the 2 wires i.e: green and white. These obviously connected to the red and black wires of the battery. I cut off the damaged connector and spliced the 2 lots of wires together as I said, to no avail. How then, did the undamaged charger charge the battery? Sorry if this is simplistic. I am still learning.
This thread is kind of a follow up to the “battery for toy drone” thread. The batteries with 1.25JST terminals appear impossible to get, so following your (and others) kind advice, I solved the problem by getting batteries with 2.0 JST terminals and making up a fly lead with a 1.25 JST. This charged up no problem, but now, as soon as I insert these batteries, (same spec as original battery: 3.7v 150mAh) and turn on the drone power switch the props immediately start at what appears to be full throttle. I have the R/C switched on before I turn on the drone switch, but there seems to be no sync now between the two. The R/C itself has new batteries and worked absolutely fine with the old battery. I wondered what I can try to get over this?
