Hi I have a few NDs/Dsi batteries lying about is it possible to use them to power servos/arduino if they are connected together as they are only 3.7v 1000mha but are very light.
I have never heard of that chemistry
NDs? Dsi?
Are you sure you are looking at batteries and not a different component part? What is this battery labeled, exactly?
As previously mentioned they
As previously mentioned they are batteries from nintendo dsi and ds lite.
Ah! The ol’ Dsi … now I got it
Well, at 3.7v, 1000mAh, I would say that little battery will give you 1/2 amp for a couple hours at just over 3v or so. Depending on the power drain of the robot, this could be enough or not enough.
I was thinking of hooking
I was thinking of hooking them up together, I was just curious if anybody had been using them. They are very light and very cheap I might charge them up and try them out.
That I would not do
Those batteries are probably lipo’s. Lipo batteries can be very touchy and have issues with internal resistance and the like. When they make multi-cell packs at the factory, they match cells for compatiability etc. Also, fancy “balancing” chargers are used --again, to treat the battery pack a nicely as it can.
Lipos can go very bad, very quick and it is nearly impossible to put out the fire once it starts. (Water makes it bigger, BTW) --Just not something to “just connect together” in my mind…
Thanks for the info, I wont
Thanks for the info, I wont be doing that then.
