I was looking at the batteryspace li-ion inventory for 26650 sizes and I think this cell is really interesting...
http://www.batteryspace.com/High-Power-LiNiCoMn-26650-Rechargeable-Cell-3.6V-3600mAh-13Wh-18A-Rate.aspx
It seems I can do a 14S2P 7.2Ah 51.8V pack for 259$ shipped with coupon code E7SEA this pack should be capable of 36 amps discharge and really small... looks like I've found my replacement triangle pack for my current 18650's pack which in turn will become the wifey's new bike battery pack
Anybody had any experience with these?
UPDATE: May 16th,2012
Got 3 cells 3.6Ah 26650 from batteryspace. Shipped via USPS priority mail with tabs for 9.75$ each.
Did a full balance charge and then a 1C discharge test. I was impressed with the accuracy of battery space discharge graphs and capacity tests. My icharger needs calibration so I won't post any discharge graphs right now. I will try to calibrate it this weekend and do some 2C-5C discharge tests with capacity to give the forum members an idea of what to expect. Overall my first discharge test I got ~3,300 mah at 1C and my icharger stopped at 3.4V under load (measured with both a fluke and a radioshack meter).
I'll keep this first post updated as I do more tests with them.
