Now that I have a spotwelder (bought it for the new boards battery) I ordered 12 new cells since the deck itself fits a 12s4p in the same volume of 12s3p with NESE when spotwelded 
If anyones interested in really cheap used NESE pm me 
on that small board is gonna be a lot of power! nice…I thought you anted to keep it lighter since you travel a lot with it.

weight is not a problem, as @Grievor stated, its my gym 
handling/size is more important.
Actually (after some thinking) it is around 200gr lighter since an empty NESE weighs 125 gr (->750gr total, 12 cells -> 560gr) I also want some modularity so I’ll go for connectors between 2s4p groups to be able to split it in 6 <100Wh packs

Lol, I didn’t this time 
the probability of flying is quite low so I just connected the with triple layered nickle, if I’ll fly I buy some cells and use the 12s3p neses I still have
How is the Nese? I’m thinking about buying some.
Loved them, they are great if you can live with the tradeoff. They take a bit more space and add additional weight to the pack. As you might have read I recently replaced the 12s3p nese in this build with a spotwelded 12s4p which is the same weigth and has the same dimensions.

That’s not bad. Beautiful build by the way!

Reinforcing battery serial connections, now I’m sure they are more than sufficient
Will sort the pictures later 
It’s triple nickel plus 63a copper braid.

Hooray, its alive again Looks like all parallel connections are good and all cells survived the soldering (It was never warmer as before when under heavy load)

My goodness, talk about overkill. How did you manage to solder that braid onto the cells? Any issues with heat?
I didn’t solder to the cells but to the nickel and used a 150w ersa soldering iron which made contact time minimal
Really? When I tried that, just the thermal mass of the copper was enough to heat the cells up. Then again 150W is more than my crappy 100W…
Edit: looked up your soldering iron – JEEZ that’s expensive

True little work horse I was thinking if I see a broken MOV-E deck it would be yours as you don’t save it. Glad it holds up

Update: I needed to send one of the motors to @hummieee to fix a broken phase wire inside the motor can. Yesterday I finally managed to put everything back together, this time with a unity I got for cheap (new but second hand, no blood unity 
)
