Selection of Right Lipo battery

[bhaazee]

I would like to know about selecting the proper lipo batteries. For example, for the following motor spec a suitable battery has to be selected

Motor Kv 540KV RPM/Volt
(What does KV in 540KV represent?)
Max Continuous Current 115 Amps
Max Continuous Power 4800 Watts
Max Lipo Cell 12s
(Does 12s means a 12-cell battery?)

Now assume the following battery spec

LiPo Battery 5000mAh 10-Cell 37V
Does this mean the battery can supply a 5 Amp-hr *37 volt * 10 cells = 1850 watt-hr?

How to find how long this battery can be used to power the above motor?
(I would like to choose a suitable battery that can run the motor for 1 hour or more)

My query might be childish. However, would like to to learn something. Can someone please explain me with simple calc?

Regards

The battery of 10 cells deliver 37 volts, so they are 3.7 volts each.

The output could be 5 amps for an hour (5 AH) and, in this case, the power would be (37 volts times 5 amps) or 185 watts assuming the battery voltage did not drop appreciably in this time.

The motor specifications are confusing. KV clearly does not mean Kilo-Volts here so you would have to seek further clarification.
However, the motor is apparently getting 41.7 volts from the battery so it could be a 12 cell battery. This would make each cell 3.47 volts which seems about right.

The current of 115 amps continuous is very high and you would have to hunt through catalogs to find something suitable.
