Hello world,
Here's the deal: I am planning on scratch building an electric ducted fan jet for a 4S system. I want to put L123's in it, but I only have the charger for lipos, liions, nimh's, and nicads, so what can I do aside from buy another $60-$100 charger? Are there any cheap chargers for charging just L123's, or should I just stick with good old Lipos? I know you can charge lithium ion batteries with lithium polymer software - i've seen it work fine - but can you charge L123's with different software?
Responses are well needed.
Thanks

the cell pro for 60 to 70 bucks would do ya.

Alternately if your charger has a good power supply mode with the LiFe's you can use that as well.

and nope LiFe's run quite a bit lower voltage than the Li-ion's and the LiPo's

Every lithium ion chemistry has a different voltage. You'll need to find out what the maximum charge-to voltage is and stay under it. Could be that one of the voltages your charger uses will work, but do your homework first and use a good volt meter.

charge for lifepo's is something like 3.2v as opposed to 3.7v for lipo right?

Not quite. Charge for LiFePo (A123 M1) is 3.6 volts while LiPo is 4.2 volts/cell.

oh
duh haha i knew that lol
owell thanks
