I'm trying to research the best lithium ion batteries to build 6 cell packs for stunt. I've done some research on the spot welder and think I've got a good candidate. But before buying the welder I want to know what the consensus is for Brand, mAh, Amp requirements, C rate, etc. I know that this has been worked out by others flying stunt and I hope for some good advice before I waste too much money doing it trial and error. Please let me know what works best for those of you who know this far better than me. Thanks

Maybe a little more on the power systems are in order. I plan to use these packs in planes that have either a BadAss 2826 820 kv, and a twin set up, of two Badass 2614 870kv. I also will want to use them on a plane with an Eflight 40 size equivalent not sure of the spec on it. The twin has 2 35 amp Castle Talon ECSs on the others I use Castle Talon 60 amp ECSs. For timers I Fiorotti timmer on the twin as well as a couple other planes. But I also use the Climb and Dive timer. I'm really wanting to phase out the Lipos and move to the 18650s. But to blindly buy cells based on some pretty iffy specs listed on Amazon is scarry. So I'm hoping for some guidance.

Thanks Dave. Gives me peace of mind to be starting with a battery that has been used with success in a stunter. I'm going to give it a shot. If I run into trouble do you mind if I ask a question or two?

I agree with Dave the Molicel p28a work well . If you can get the B version even better. The Epoch (p28B) also works great. It is just a re-wrap so it is the same cell. DO NOT buy these from Amazon or EBAY. Buy from where Dave suggested. There are counterfeits out there and they WILL NOT work!!! I have not tried any other brands. These work I have used them all.

Here's some helpful info for your building adventure.
I like building 6S packs with these multi-colored 7-pin, 30cm leads.  Makes keeping track of the node easier during building.
