Should be fine. I have a sunkko that is a very similar model and it does the job no problem.

With sunkko sometimes you get a good spot welder, sometimes you get one from a shit batch
I would reccomend you to pay a battery builder to make you a pack if you only need one or two, but if you plan on making more than a few packs then get a sunkko from amazon because of their return policy
or even better a boss/kweld welder

i got that exact one. Works fine for me 
Just use the electrodes on the welder if u want to use pure nickel. The pen can’t carry enough amps for pure nickel

Thanks guys. Will consider buying it
So I’ll be starting work on a 14s4p this week for a onewheel + range extender. It’s going to fit in a laptop compartment of a backpack so the space constraint is interesting. 12 cells wide at the bottom (3 4p groups) and 5 cells tall, with the remaining square being dedicated to the BMS.
I’ve drawn a few different diagrams but would like to see how the experts would lay it out given these constraints.

Definitely gotta look out for sales on the P42A. I was able to pick some up for 7.50 from IMR a little while back.

Just wanted to share this, in my opinion, awesome deal!
Fully adjustable, 0-60V, 0-5A power supply/charger. Especially if you have few batteries of different voltage, or you want to charge your battery up to 90% for example. Great for charging individual cell too.

Building a 10s4p 30q pack that will break down into 5x 2s4p packs for safe air travel… pretty sure I’ve got it figured out, gonna use 3.5 bullets to connect each pack and 2pin connectors for balance wires.

I have Gophert 0-60V, 0-17A and I have ordered one that I mentioned too. I really do like those adjustable chargers.
What I really want is a 10S ballancing charger and tester and discharger some hobby chargers go up to 12S lion but havent seen one under 500USD. Jeyu has one in some of his yputube vids it can charge at 1200Watts
Check Alibaba.com or trampa website for this one
They as well sell a bigger version for up to 24A.
Think price was around 380$
Also for all who searching for an adjustable power supply, this seems to be a good value for the price.

Ive got a guy who wants me to build a 12s8p 30q for a trampa monsterbox and he already has this charger that he was running with lipos.
Will it work with the new pack?

If you route out the balance wires to two 6s jst plugs than it shouldn’t be an issue.
The difference between a charger and a psu is a charger monitors your charger when you bsttery is full it stops. if you keep trying to stuff energy into lithium it never ends well.
