I recently purchased a NiMH battery pack with a Futaba J connector. I also bought a charger, but it does not have the right connector. The charger does however come with an adapter to alligator clips and a red and black wire. I looked on my batter and noticed that there was only a black and red wire actually in the Futaba connector. I was wondering if it would work to connect two pins to my alligator clips, and then connect them to the battery. It is for a school project so any help would be greatly appreciated. Thanks!
Sounds to me like you have two incompatible items. The Futaba battery pack needs a charger made for it. The Futaba battery if it is four cells, is 4.8 volts, 600mah, or 8 cells, 9.6 volts, 500 mah. You CANNOT charge either one of them with a 12 volt battery charger. You need a charger that comes with an R/C transmitter, designed to charge their batteries. Their charger comes with a female Futaba J connector which matches the battery connector. Please do NOT try to charge the battery with the WRONG charger.
You can, yes. The only real danger would be connecting the battery backwards. There is also a better chance of a false peak (charger thinks the battery is charged, but it is not quite), but that poses no risks. Just be careful to hook it up correctly and you should be fine.
