Tell us how Antigravity's packs fare!

duly noted! thanks.

ok, i apologize for the massive amount of posts. i have not done carbon fiber layup a lot, and i guess if i am going to have someone invest, i am at least going to need a prototype, as you suggest. i can make a casing for the pack without having to invest a huge amount, but without the cells in...

speaking of mounting, i could make a flat box with 5 sides that is slightly larger than the pack so it is like a tray. i would then put several pieces of carbon rod into the sides and install velcro straps going long and wide so the pack is Very secure. you could mount the tray in any...

i would do such a better job. and besides, the prismatic cells better lend themselves to series AND parallel connections. their tabs are on the same end. i'm tellin' ya folks, all i need is one person with $300 burning a hole in their wallet (i have already shown you my costs, i would have to...

6 35/64 x 8 15/16 x 1 7/64 total internal pack dimensions. with the kevlar/carbon fiber shell, figure on adding about 3/16 to each dimension. it will be a solid design that i have decided needs to be serviceable so that if a cell dies, it can be pulled out an replaced. the problem with that...

:p

i really wish i could afford to buy all of this stuff to help you guys, but i am honestly strapped for cash.

suggest getting qty 2 of the epoxy. having too much can be cut, trimmed or sanded away, having too little will make the integrity of the shell fail. 4 cells is all that is necessary for the battery. one can of sealant is all that is necessary, and 1 meter of each of the wires is all that is...

as i said, i will get all of these things if someone puts the money in my paypal account. i will forward ALL information to the payor so they get confirmation of the purchases of all of the products. i will take pictures and post them on this thread. as soon as it is all assembled and adhesives...

oh, also a foodsaver system for the vacuum bag to squeeze the whole thing together so it can set hard.

that's the thing. i am what you all might call poor folk. all i need is someone with an extra $300 laying around that i could use to get what is necessary to even make the prototype. all i want to do is help. fact of the matter, i won't even charge above my cost to do the first one. whoever pays...

of the 26650 cells

actually, the voltage sag at 180 watts per cell takes it all the way down to 2.4v/cell after only discharging 40% of its capacity.

i just found the data sheet on the ballistic cells. http://info.a123systems.com/Portals/133376/docs/A123%20Datasheet%2026650M1B.pdf max discharge for 10 seconds (burst) is 120A per series set. that's a max of 480A. continuous discharge is 50A per series set or 200A total. cycle life is 1400...

the power output of each cell is 1200W. since there is 65wHr specific energy capacity in each cell, the C rating for a 10 second burst is an average of 18.46C still, that's 363 amps. the 60C burst of the 26650 cells that the ballistic battery uses is for 10 seconds as well, but external...

i would also shrinkwrap the terminals and polarize them so reverse polarity is less likely as well as using red for positive and black for negative. also, to ensure that everything is sealed, i would get that spray rubber stuff you see on tv that the guy sprayed on the screen door that was...
