Solar cells and li-poly batteries

Solar cells and li-poly batteries

(OP)
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?

RE: Solar cells and li-poly batteries

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.

RE: Solar cells and li-poly batteries

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.

RE: Solar cells and li-poly batteries

soare0 here's some of the many links relating to Li-Po safety.

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..  :)
