I did, and I made a lot of assumptions about where it would conflict with case or electronics and came up with 8 x 24 x80. I still had several problems unanswered. 1) did the pack have its own BMS chip. looking at it I think I only saw the attaching tangs and NO BMS. 2) was I trying to push too much into the case (fire Hazzard), 3) Thinking I knew enough about the battery specs, Where would I find such a battery! I purchased the FULL WORKING OPTION because I wasn't Shure about all of this stuff originally. I would think that if you have a link to a distributor you would get continuing benefit ($) from this link. Dave, this was a very curse response.
