hi

for a diving light, i need to create a 4s3p battery pack (lithium). I can have max 2 level of battery in a delrin cylindrical.
What could be the easier wiring for welding?

I put all battery on the same side... but it's not mandatory...


thanks

 

4s makes 16.8V when fully charged and you need a low voltage sensor set to about 12V to disconnect the battery preventing it to be ruined. Does your light work at 12V to 16.8V?

 

a led driver for an xhp70 is used...

 

 

seem easy to do welding

 

Don't forget to add the cell balancer circuit too!
