GP2200 4/5 Sub C

[sjslhill]

We should have these by Monday....will they be the next world record setting cells? Reports from Germany say they are great, I have not tested any yet.

thanks

Hey Steve,

Sounds interesting, can't wait to hear what you think!

Steve,any news on the new "shorty" cells? I'd like to squeeze 8 of them in my little hydro for a couple SAW passes in O sport! Jay

They have some 3300mah sub C's and enen panasonic makes a 3600mah. Zapped and matched, like 1.192v each, very very high powered cells B) Ballistic batteries makes some nice cheap 3300 cells. i think that the site is www.ballisticbatteries.com.

The cells which are the subject of the thread are not sub-c cells, but shorter versions. Typically, shorter cells don't have the low IR that longer cells have, and with today's motors and hull designs the slight loss in weight is less important that the greater power of the sub-c cells. If new technology means that the smaller cells have the same voltage under load (and the same IR), then that would be a major advantage for the smaller cell-count boats in particular. We already have more capacity than we need with current 3300s for oval and SAW boats.

Jay, the F5B guys are running these 2200's, I think they will work in WW trials. I have not tested them yet though, my equipment needs to be changed for the shorter cells.

Neu tested the 2200's (unzapped unmatched) at 60 amps and the output at midway thru the discharge was 63 watts per cell vs 64.2 for the 3300's

The power to weight ratio was 1.43w/gm of cell vs 1:1 for the 3300's the acceleration looks exciting.

IMO certainly looks the hot option for the 4 cell classes and if acceleration into the traps is as important as the higher cell count guys think it may be the ticket there too.

STEVE i'm also interested in these cells for a N-2 Offshore Cat project. Can you give us an idea on the weight savings over GP3300's. Also would GP2200's be NAMBA legal guys?

Also would GP2200's be NAMBA legal guys?

you can run sub c or lower and be legal
