New 35C hyperion G3 packs arrived...

[zeropointbug]

So I did my first run with the 35C packs, and my first run with lipo packs period.

holy crap, holy crap, holy crap

I AM IN LOVE!

I swear if I never knew better I would of thought I was running a 1521 motor on my 7s2p A123 pack! Keep in mind this is the exact same setup as before, same gearing, whatnot. It is such a jump in performance over a 7s1p pack, like I can wheelie at almost any speed! It's insane! I am doing the same with less than 3/4 throttle vs. 100% throttle over the A123 pack, punch wise.

This is the first run, and Hyperion says it takes 5-10 cycles to reduce cell Ri, and still over the next 100 cycles as well (although to a lesser extent). Each 3s pack has a rated 0.004Ohm Ri, or 0.008Ohm for 6s... that is the same Ri as one M1 cell! I don't have my 720i charger in yet, so I used my power supply to charge them up using a 4.1v/cell CV voltage, so I am most likely not seeing the full performance of these bad boys.


Notice the packs voltage holding ability! 3.7v/cell @ 100 amps, yikes. That's 23C discharge! It barely gets below 22volts for bloodin sakes!

Welcome to the World of Lipo! Mr. A123 Guy! LOL

Sounds like you're having fun.

Well, I'm tellin you, I can't wait until tomorrow to run it again during the day. I know, I have been a very A123 guy, probably due to the fact that I am an electric car enthusiast/builder and A123's have been better suited(cost, cycle life, safety) for that application... just carries over I guess.

Funny how it holds about 3.875v/cell @ 30 amps. That's heavy duty. Also, 3.7v/cell @ ~85 amps.

This run I was extremely hard on the throttle, basically doing high speed runs in the ditch while doing WOT wheelies at near top speed.
