Question regarding safe limits with 16.8v 1800 mah 65C-130C 4s LiPo.

Battery will be in a PWM box. I took some math from another site with a similar battery and it states:
Discharge: 35C (63 amps) Constant / 45C (81 amps) Burst
Max wattage capability (continuous): 1058.4 watts @ .0266Ω
Specs of battery I'm using
Turnigy nano-tech 1800 mAh 65-130C discharge 4S cell


So I want to verify I could run .07-.09 builds around 4.5v with no issues. Maybe go up to 5v but the lowest I build is around .07 and at 4v it's still a very hot vape so 5v is unlikely. I asked on another site and was told "PWM still has the same limits that a mech would. Which means with that battery you can't build under ~.2 to stay under the continuous rating. A little under .1 to stay under the burst (which I wouldn't trust at all)." which I don't think is right. Figured I would ask here.

You will want to do what the RC guys do: Use an ESR/IR meter to verify both the individual cells and the pack before calculating usage based on the Lipoly Objective Performance Calculation Tool. The ESR/IR meter from Wayne Giles on RCGroups has been the de facto hobby-grade standard for years.

Looking at steam engine battery calculator, inputting the batter spec just 1800 mah and the total combine mah from all 4 cells I should be fine to run about any build long as I follow standard lipo safety guidelines I shouldn't damage any cells. With that I know flyers pull way more power out of these cells than any build I'm capable of building could.

Hi,
you should consider the new graphene batteries from Hobby King.

These batteries appears to have very long cycles life at very high C discharge rates .
