juggernaut battery

[tinasdude]

If someone could help, I would like to know the specific cells that are in the 11.6ah battery from the juggernaut kickstarter deal last year. Thanks in advance for anyones help. I know they were supposed to be samsung or sony. Need to know the specific cells. Looking at a possible 2nd battery. Apparently some cells are better suited for power than others. ex for off road and hill climbing. Thanks again

From the Kickstarter web site:

The upgraded battery is still 48V nominal. It has a higher amp hour - Standard batteries are made of 2600mAh cells which give a capacity of 48V 10.4Ah when connected in a 13s4p format. The upgraded battery is made of 2900mAh cells which give a capacity of 11.6Ah when connected in a 13s4p format. The 11.6Ah battery will last about 11% longer when compared to the 10.4Ah battery under the same use case. The physical dimensions of both these batteries are identical.​

Not 100% sure, but I believe the cells are Samsung INR18650-29E 2900mAh seen here:

Thanks Fred. I went to the kickstarter site and missed that info. Appreciate it. Looking at 52V battery that is apparently using some more recent cells with better specs. Maybe I should wait a while. Technology and pricing seem to be moving along

Samsung announced their INR18650-32E cells last Spring, but I haven't seen that spec on any packs yet. Hope to see it soon, 32E packs a wallop!

Thanks J.R.I was eyeballing the 52 volt dolphin pack from Luna with the panasonic cells. Good stats on the cells. Reading what I can find about batteries. Luna has some good info. Slow learning curve for me. 2 different cell packs. Apparently one cell type withstands more rugged use than the other. But the 2nd is better for distance but doesn't hold up as well off roading and big hills.

Reading further on Lunas site either of their batteries should be fine for 750W BBSO2. One packs cells are 3400mah. That is what I will be looking at. 13.5ah in a dolphin battery. I am thinking with a lower tooth chain ring on the fat bike and the 52 volt battery and it will be more than I will ever need for my purposes. http://lunacycle.com/blog/
