Yeppers .
Need range for the tow truck to keep up with my wife’s RadRunner when we tow the kids around.

how much range do you have with the old one vs the new one (expected range ) ?

It currently has a 10s4p 40t. And when towing on these gravel trails with a few hills here and there I am barely getting 12 miles.
I really hope to get 20+ with the new pack.
But I’m 235. The trailer is like 25 and the kids are around 40. So… Pretty good amount of weight to move…

you should expect more than 2x range, 1305.36 Wh over 592.
I think 25mi is a solid expectation
also, thats like 53 Wh/Mi

nice. does your gearing account for towing? i wonder if the motor is out of its efficient torque band.

I am running 10/62
It’s just what I had ob there before which was intended to be the most possible torque without being too slow. So it does hit 25 mph.
When I switch to the 12s I’m going to 9/62.

I’m not smart enough to know how to hit this.
The set up is a unity and flipksky 6384 190kv motors.

Yeah. That is how I roll on most set ups.
Much prefer torque over top speed.
lol neither am I. I just understand that there is essentially the green line below is efficiency
I figure youd want to hit it right in that peak there for your sort of flat groung cruising torque needs

Happy to help 
Not sure how he did his, but on my eMTB batteries I solder a full length of stripped wire or braid along the length of the nickel before I spot weld it to the p-group, then fold it over once the p-group is done.
Like so:
If you already welded the nickel onto your first and last p-groups, then probably dont solder down the whole length, as you are going to want to limit the heat transfer to your cells.
Just do pools of solder evenly spaced like so:
