Also talk about balance wire connect points. Thank you

Thank you so much for making these "unobtainium" cells available for us here at ES!
Gonna have to see which pouch cells (these or A123's) the best in my cargo pods based mainly on size.
Sounds like the 25 AH High Energy would be a good fit hmmmm.

Balance wires will connect just as they do as the Turnigy packs, with a connection at the most positive, and most negative point, as well as every interface between tabs. The 16Ah and 25Ah boards will basically be scaled up versions of these, to allow folks the option of manual offboard balancing, or a centralized BMS.

I want to build 1S3P, 25 Ah. Is there MSDS sheet available for the 25 Ah?
How do you solder to the battery tabs? Is it aluminum like A123 20Ah?

I keep seeing 1C and .5C charge and discharge cycle life, really interested in the higher C-rate cycle life (to 80% of capacity left).

thanks so much for making these cells available. Unfortunately (well ok, price was great and cells look good, so unfortunaltely might be the wrong term ) I just bought a batch of a123s so I dont need cells right now but if Ill need more, I would be happy to buy from a company that actually is willing to sell their product to us!

What are the safety design parameters? Has the cells passed EUCAR or SAE destructive testing?

He has worked through two frames, three fairings, and two motors, but the same pack. Two cells were physically damaged, in a wreck, but the pack is still going strong, I believe. He is not a techie, but I suspect he would be glad to tell you his experience with them. He won't be hanging out typing on this, or any other site. He is pretty quiet, and focused.
