2200 2s lipo qestion
guy what a good idea of run time with a zippy 2200 2s 20c with sidewinder 5700 in a b4 and t4????
#2
It may not be quite enough discharge curent capability , but I would guess if ran easy the runtime shall be about 8-10 minutes.

i thought 20c was good???? im new to lipos cant you tell ...lol
#7
Yes, im new as well and just bought some 4000 lipos 28c's....how do you blow the batteries up??
#8
maybee he is saying the motor will pull to much from the lipo.... so does that mean it will melt down???? i dont beleave that... i see 5000mah 20c so there not good for what i want eather because there 20c????

20 C is neither good nor bad , but rather an indicator of the battery's ability to discharge at various speeds. Larger number is better.
1C = 1hr
2C = 1/2 hr (twice as fast)
10C = 6 minutes
20C = 3 minutes (ten times as fast as a 1C)
Since "C" stands for capacity then the two numbers multiplied together indicate the current capability.
A 2200 mah battery discharged at 20C = 44 amps (not enough for a 5700 system in a fast 1/10 scale)
A 5000 mah battery discharged at 20C = 100 amps (probably enough for the 5700)
Increase either number or both so that when multplied together gives a HIGHER current than the system it will power. Please also note that the numbers given by vendors/manufacturers may or may not be accurate and should be defined as to what they are describing as well.

This particular example (if we trust the numbers) works out to 4000 x 28C = 112 amps and is probably enough for a 1/10 scale set-up.
To damage battery just pull something more than the battery is capable of and it'll overheat. Example: pull 200 amps from it.

so, i guess i would have to look at my motor(a novak 8.5) and see what the amp draw is to determine if it is too much?! Would the esc effect this at all? I bought the havok/ 8.5 brushless combo if it helps

Yes to the motor amp draw. If the esc did limit it it would probably burn up, so hopefully no. I agree with gulio, as long as it's not overgeared you should be fine with the 4000 28C.

cool, thanks guys
