I'm essentially trying to create a portable rechargeable fan, I have the following components:
3s 2200mAh LiPo battery
2200 kv brushless motor & ESC
I have everything tested and working (right now I have it connected to a potentiometer and Arduino for speed control), but I'd like to make this device compact and add a charging module inside the electronics housing (something like this USB LiIon/LiPoly charger [v1.2] : ID 259 : $12.50 : Adafruit Industries, Unique & fun DIY electronics and kits) . However, I'm incredibly confused with how these things work. It looks like all of these modules are for single 3.7V cells, and I can't find anything for a higher voltage. I did find some multicell chargers, but my battery is packaged as a single cell so I don't know how I could practically connect that. I definitely think I'm missing some very basic theory here, but haven't been able to find any practical applications as a resource for this particular problem (everything I'm finding is for single cell applications).
Thanks for your help!
If that is your Lipo, then the mutli-pinned white plug is for battery management.
It also comes with a battery management box, can't you put that in the with the Lipo and have a plug/socket to connect the plugpack when you need to charge?
You neither should nor can use a different charging module. My only concern is whether it is appropriate to leave the charging module connected while not charging - whether it might actually slowly discharge the battery. I suppose it should not but you can't be too careful.
