1) The maximum amps the battery can deliver is calculated by multiplying the capacity times the C rating. For example: A 2.2Ah battery with a 30C rating will be able to deliver 2.2*30 = 66 Amps A 3000mAh(=3.0Ah) battery with a 50C rating will be able to deliver 3.0*50 = 150 Amps.
2) The amount of amps the system will use depends on your choice of motor and ESC, the amount of amps the motor will use is usually listed in the specs of the motor
I agree with you Shunra1, i only add this:
if you use a 2.2Ah and your consumption is 2.2Ah it will have a duration of 1 hrs, theorically because you can´*t leave at 0 the bat. if your consumption is 2.2Ah*30c your bat has a duration of 1/30 hrs.
am not agree with that , if you use lots of esc like my x8 i need 8 esc and if you need to repair your machine of a faulty esc or just tune the esc you can remove fast and fix the problem also i have no lose because i use piece of shrink to secure the connector and it take only fews second to removed if needed
spitfire2010, I was referring to what 3w flyer wrote. "why from 4 x 3,5 to 4mm just go from 4x4mm to 1x4mm"
The problem is that if he needs 4x4mm to go to the 4 ESCs, his current (Amp) load is probably too high to be fed into the one male 4mm connector. An analogy would be if you were installing a sub electrical breaker panel to your home's main breaker box and the sub box had four 15 Amp circuits, you wouldn't connect the sub box to the main box with 14 gauge wire, you'd use 10 or 8 gauge wire.
I would use these ANY TIME in my Quadro's. Up until now I made them myself, but these or nice, And I believe these can handdle the current without a problem !For this price you can't can't heat up your Iron en solder them yourself
