Well obviously you know something about it as you took the time to post the IR measurements.

In a nutshell it reports on the quality of the battery and how well it will hold voltage under load while staying relatively cool.

Basically the things you look for when purchasing a premium pack.

Re: Pulse 6s 3700s 45C

Sorry for the late reply.

Charging aside, we are more interested in the ability of the battery to discharge. More specifically, in bursts of energy as our output power in never linear. Batteries with higher resistive values sometimes can't supply their intended rating and result in a voltage drop instead. Some ESC's erroneously read this drop as low battery and jump into voltage cutoff or slowdown.

Mind you these are more extreme cases of IR.
