Damnit, the Lipo battery industry needs better standards!

Its starting to look like im going to hobbyking for Lipos now. Wonder if theres any major differences between turnigy and zippys

The Turnigy's are better IMO.

They have noticeably more punch, run cooler and more mah are returned on the charger.

The Pack's I am comparing are Apples to Apples.

4S 20C 5000mah Zippy's
4S 20C 5000mah Turnigy's

My E Revo setup:
MMM ESC
Medusa 36-60-1500kv geared 22/40 using Mod 1 gears.

I had to upgrade the driveshafts to Traxxas CVD's, because it kept snapping the stock Drive Shafts. I run a tight slipper.

This is in an E Revo. Notice the gearing, this isn't a "light" amp draw setup.

I've seen discharge graphs on both the 20C/30C Turnigy's and the 30C/40C Turnigy's. I'm pretty sure they are the same cell.

Compare the weights and cell sizes.

I also run a set of 30C 5000mah Turnigy's and notice No Difference except the 30C packs come with 8Ga. Wire. Yeah, 8Ga.

The 20C packs come with 10Ga. Wire.

The Turnigy's will outperform SMC I'm sure.

Here's a 3S Turnigy 20C 5000mah discharge graph. It's half of a 6S setup being ran in a Savage Flux.

The Max was 112 amp draw. If you look on the graph at the 112 amp spike, it's holding 11.1 volts. That's 3.7 volts per cell.

That's more than 20C.

Can you elaborate a bit more on what i'm seeing on this graph? its kinda fuzzy and hard to read the details.

The Blue Line is the Voltage. See at the top, the pack voltage at the beginning is about 12.5 volts. Almost fully charged.

The Red Line is Amp Draw. Each Red Line Spike is a stab at the throttle.

The Blue Line is pack volts.

The numbers on the right side are amps. The numbers on the left of the graph are for volts.

Pick a Red Spike on the graph, then go to the right to see how many amps that spike peaked at. Then under that same spike, see how low the blue line goes, then go to the left for the voltage value.

For each amp spike, you can get an idea of how the pack held voltage under the load.

I hope this makes sense to ya.
