Not sure what you are looking for. Something like this?
Thank you! Yes, something like those but that can hold each row let’s say at 45deg than the other, like when you glue the cells, I need to reduce the width as much as possible.
On Aliexpress, you have different types of oblique battery holders

along with varying sizes of oblique or “W” pure nickel strips
Here 23.5 x 18.3mm (no plastic bracket), they exist in larger pitch to take into account the bracket dimensions

Does soldering 18650 cells damage them?
I have done some testing with a thermal camera and come to the conclusion that the maximum temperature the cell is exposed to during soldering (with the correct technique) is within the batteries rated operating temperature.
See attached picture and video. Maximum rated discharge temperature for Samsung 30Q cell is 167°F (75°C). And the peak temperature during soldering is only for a few seconds.
Soldering cells does not expose the cell the temperature above this value.

Tested fuse wire.
1/2" length of 30awg on both battery terminals.
Fuse wire does not exceed the temperature of the battery cell at 10amp discharge rate.
The fuse wire voltage drop remains below 3%.

Thats quick! Looks good, thanks for sharing.
I do believe soldering is an option if you know whats you are doing. Check HBpowerwall, in the past he soldered 1000’s of cell this way, still in good operation.

Thx. I’ll let you know how it works. I did all the testing. The math says it should work good. Only one way to find out for sure! 
A very nice job but too fast to attract the most sceptical among us. I am convinced but would you have a normal speed version of the basic tasks ? With commented or sub-titled best practices it would be a must

That’s a good idea.
I’ll try to do something like that on the other battery builds.
I have some progress to report. The battery is in the testing phase.
Still need to install fuses, waterproof the plugs on my version 1.0 homemade (temporary) enclosure, and do leak testing. But, almost there with the battery build.
I need to start focusing on building the board, mounting the motor, and getting a working ESC.

Hi, what connectors are the big ones?

Hi. They are marine trolling motor plugs. Rated at 70amps. But, that is a true marine rating. so equal to +300 amps the way R/C connectors, and bullet connectors are rated. They are designed for saltwater use. So no worry about corrosion. They fit 6 gauge wire no problem.
I used these because they were easy to mount and make waterproof. They are heavy, but I removed the third connector, and plan to do some more mods to reduce weight.

Thank you for the hint!
With these MARINCO connectors, we are not that far from the LIFT ones. Would the LIFT ones be from a military source… 
?
Other candidates :
NOCO: Amazon.com
Journeyman: Amazon.com

I’m not sure I would pick either… The connectors fliteboard use (amphenol surelok) are widely available and cheaper.
The lift are most likely custom.

Thx for mentioning the amphenol surelok plug.
Mouser electronics has several promising looking plugs

Just ordered a set of slp-b50 series. 
Its not cheap, but looks promising. We will see…
I am confused about sap-b50 series. Only male parts are listed in mouser can’t find the mating female connector.
Same with there position version:

Does these connector comes with female and male already?
