LiPo Battery C Rating Confusion
Hi - firstly may I say that I've found the information on your web site the most comprehensive and understandable that I've found on the web.
I'm new to RC modelling although I have a background in electronics. I'm starting from scratch to look at a model hovercraft, the SRN1 - the first ever. I'm trying to understand about motor selection and all that goes with it.
Obviously articles are geared to aeroplanes and not hovercraft - but that's what I'm researching at the moment.
Anyway, my question - in the article about LiPos there's the following paragraph -
For example, this 2200mah LiPo battery pack with a 30C rating can safely provide 30 x 2200mah = 66,000 mA or 66 amps.
Sorry, I can't see where the "C" figure fits in here. The figure 2200mah is the capacity of the battery, i.e. 2200 milliAmps / hour. It would supply 2200 milliAmps for an hour or 1100 milliAmps for 2 hours, etc.
I can't see that multiplying the capacity, in units of mah, would give a result measured in Amps. What unit is the "C" figure?
Sorry if this sounds a bit confused, any comment/assistance would be very much appreciated. thank you.
