Re: [Gumstix-users] Li-PO battery Packs

[Ben F. <be...@fi...>]

C ratings indicate discharge/charge rates. A 2000mah pack with a 10C 
continuous discharge rate would equate to a 20A maximum discharge rate 
(2000mah * 10C = 20,000mA). Also keep in mind that these limits are 
often overestimated, and lithium batteries have a wonderful tendency to 
blow up if discharged too quickly.

The C rating you need depends on how much current your equipment draws.
