Check out this battery pack


Recommended Posts

I don't know if I can splice a wire so short. They're 1/4" and my Wago Connectors require 1 /2" leads. I don't know how they tested these, and why they are called refurbished. They're just blowing smoke, and probably dug them out of a dumpster.

I  solder  every one of my lithium ev car battery  pos and neg  ( over  50  solder connections ) .  This solder from  ebay  is easy to  solder anything  copper or steel  or copper clad alumin wire .

 I've seen plenty of examples where it's actually been lead free solder.

The  ebay solder  has a very low melting point so it is safer to solder that close to his lithium ion battery  and the solder melt and stick fast to a  short wire .  It is still danderous  and I  am very careful  to watch the temperature  with a  temperature gun  as 400 degree F  it  will explode .  Wood  burn at  500 degree F so definitely keep  the battery away from wood .  The solder may have lead  .

I'm practicing my soldering skills today. All I have is a basic pen type iron, but if I do everything right, and wait long enough, the solder will melt. I fixed a terminal on a 12V sealed battery. When I soldered inverter cables, I used a propane torch.

When I soldered inverter cables, I used a propane torch.

All of my  awg 4  cable are solder with propane torch  far away from any battery .   I  use the 200w  solder iron next to the battery  and watch the temperature  .   The solser I use melt at  250 degree F  because the lithium ion battery will explode at   400 degree F  .

I also use that solder.

Be careful with Chinese sourced solder claiming to be 60/40 (ie regular electronics grade solder for people that are old enough).  I've seen plenty of examples where it's actually been lead free solder.

It is Indian solder as far as I can tell. The company has offices in NJ and Karachi, India.

Hi Robert,

I don't know anything about your battery , but could you open up the case, giving you more wire to work with?  Or perhaps you could replace the entire wire from whatever it is connected to inside?  An unspliced wire would always be preferable.

If you can't do the above, crimping two wires into a  copper sleeve would be a better connection than soldering, and eliminate the concern over solder quality and/or soldering safety. (Then add heatshrink)
