for 160 shipped. I dont realy want 25 of them. maybe 16. anywere else to get them?
at that price that puts them at 6.40 a cell.(not bad)
Also. were are you getting the copper jumper bars? I assume they are specificly made to bend in half to make end to end packs. And one last ? since im super dumb on a123 cells(or similar) but it sounds like these cells are a little less sensitive, to overdischarging. and you dont need to balance them like lipos. What amp can you charge them at? 1c? higher? and are you just using a lipo charger set to 4 cells? any reason you couldnt charge 8 of them at one time on something like a mrc 989? thanks guys always looking forward to good info on these boards.

The Ebay seller you listed is where I purchased these from. He shipped fast and described them well.

I bought a quantity of copper battery bars from Ebay a long time ago. I don't see any flat ones posted now. In the past, I have cut narrow flat strips from a sheet of copper, kinda time consuming but works well also.

1C charge rate is a good rule of thumb for anything lithium ion related.

The charger I use is a MRC Superbrain 989. 8S wouldn't be a problem for it at all.

I still have my bashing packs, but there are alot of other uses for these cells as well.

On a recent trip to Bass Pro Shops, I found this Lantern. Out of the box, it requires 8 D size batteries. The manufacturer claims 10 hours of runtime per set of batteries.

Fishing season is here at last!

I installed 12 of these cells in the lantern in a 4P3S configuration. This provides a total of 10,000mah and around 24 hours of straight runtime per charge. Enough for an entire weekend of camping.

There is also a pcb installed now with a lvc of 2.4 volts per cell to protect the batteries in case I fall asleep or something and accidently leave it on at the end of the charge.

Check this out.
