19" DIY Power Packs

Go for a TS100 with a big tip. It is one of the most versatile soldering irons you can imagine...

Yeah, it's a good iron. I use mine for pcb work. Altho, mine has the really small tip. I've seen some of the reviews with the larger round tip and they did pretty decent work with it.

Sorry guys. Progress is not so fast as it should be. I had to work on other projects...
Today I was able to spend some time to test the new soldering iron and build a new version of my busbars.
As Korishan said, I use one XT60 per busbar.
What do you say?

And I got 2 of this 8s BVMs to see if the cells are drifting.

I like how you used the the XT60's per busbar.  I am going to use split bolts on my full size 48S x1sx140p battery, as shown in the top module (Prototype 2) but XT60's will work great on these smaller experimental 1s x 40p battery packs where I will be attaching them and disconnecting them a lot.   I might be soldering XT60s on Prototype 3 and Prototype 3revA tonight.

Nice woodwork Ryan Smile
Soldering XT60 is not as easy as it sounds.
Because I am a noob in soldering my first and my second try was a disaster.
I think I need a solderingbootcamp

Just watch for possibility of shorting, the split bolts look pretty big in the pic - might be the camera angle?  Could do it nicely with crimped eye/loop terminals as well (probably cheaper too!).

I haven't decided 100% on the size of bus bar wire or battery module to battery module bus wire for the full size finished product.  Right now it looks like I will be using 4 AWG as the battery pack bus wire, and possibly 2/0 or 4/0 AWG as battery module to battery module cable, so Crimped and soldered eye terminals are a possiblity.  I will just have to see what works out the best when I get there.  I will be pulling 100kW of power at peak for a short time and I can pull about 54 kW of power continuous.  The exact Amps will depend on which motors and controllers I go with.  No matter what method I use, these electrical connections will look like electrical tape covered golf balls when they are finished.  And will they will be treated like High Voltage connections as much as I can.  (Hard to turn off the batteries when you work on them...They are always on)
