Almost done building the pack for my bus.

I was going to do this and after seeing the 4x

I have decided on this 4 by 20 cells

I found it so much easier to get solder on the battery first, then reheat to get the fuse into the solder.

Batteries are all tined ready for bus bars and fuses.
Going to use the 3 wire twist with 12 awg
 
Looks good

The china 300 watt is way to big, i would recommend the 100 watt

Checked out the 8 awg ring terminals and they fit perfect with a .190" id

The 6awg have a .230 id

Somehow i ordered non plated the second time.

That all seems to come along nicely!
What are you planning on isolation when you place it in the RV?

I want to place the first pack I'm making in our own RV.
What about the BMS?
 
Nice.

Just change the tip on the iron to one that is smller in the top
 
Im going to sandwich it between 2 sheets of plywood and store it under the clutch.

bms is built into the sbms100

I think i can just grind the tip of the soldering iron down.
 
I did one under the couch in a friends bus. Was nervous about air flow and someone spilling drinks though..looks good man. Why did you by copper instead of smashing some tubing to make your own eyelets? How's that iron treating you? I plan an in depth side by side review of tools very soon, just eating to get my big torch in..
 
I will be making my own ends next time.
I only tried the iron on a few cells to make sure it works.
it's a monster and you wouldn't want to lift it up and down for 500 cells.
takes a LONG time to heat up.
after its hot i dont care what you touch it to, solder flows in 1 sec.
Thinking of buying the china 100w iron, same style just much smaller.
 
Yeah 100-150W is generally good enough if the tip has enough mass :) The 300 is massive but yes it is good for solder large lugs or thick cables :D
 
The 300w melts things it doesn't need solder.

Charging with my SKYRC IMAX B6 is going very SLOW at 50 watts

I think its time to order solar panels.
