Solar cells and li-poly batteries

[ce1202]

Ok i was wanting to know if you could charge a lithium polymer battery on a solar cell without haveing to use the lithium charger?

Well I suppose.. But really you would still need a relatively sophisticated charge controller to do it correctly and protect your investment in some expense batteries. Also those batteries can be rather dangerous if abused. Not as bad as Li-ion but worse then then the rest.

Why they may become dangerous? I'm thinking at, let say, a 500mAh accu.

However, if I would like to recharge my cell phone batery for example,the charger already exist, but I assume that this is not about a mobile phone batery.

Read this antidotal story about Li-Po:

You can Google up hundreds of articles like these.

To repeat myself.. Yes you could use a solar cell to charge a LiPo battery if you personally monitor it WITHOUT FAIL and terminate the charge when it should be terminated.

Like when you are stuck on a remote island and your satellite phone went dead and a ship wreck near by had a solar panel on it..
