You should solder blob your batteries, it is saver. If you use it without buttom top
- the shrink wrap can tear, which make it more likely to short.
it could be one battery doesn’t make contact.
You plan to bypass the springs? Hell make sure the positive side has good contact.
= You need nipples on your batteries!
This should be the first thing what you do before you start to mod the rest.
You should search the Q8 thread for solder blob or solder boob or your batteries.
You should find plenty how to dos and explanations why its save/better.
Soldering on aluminium is normally PITA. But I am no solder expert.
@FlashyMike Thanks for specifying the size tested and size recommended. Wow are they bigger than I thought. I’m going to put that on the back burner and see how upgraded springs do. But I will continue to investigate it.
@ Joechina Thanks for the concern and rationally expressing your opinion. Yeah I know about the risks using these flat tops. They are slightly raised flat tops, so they seem to be connecting fine for now. I have an order from mtnelectronics.com with a bunch of brass buttons for soldering onto my batteries. I know I can just solder blob/boob them, but I like the idea of brass tops. I also ordered the 4 different types of springs for modding and testing. And I got some battery shrinkwrap incase I get any damaged battery wrappers, and planning on using it to “snug” up my batteries in the tube so they don’t rattle as much.
As for the aluminum, I am going away from that. I wasn’t aware aluminium was so hard to solder. I knew you could weld and braze it. From what I read it can be soldered on, but not worth the extra effort and special supplies. I am just going to use the extra tail board that I ordered to mod and playwith.
@ Khas Thanks for that. I ordered one. ~$5 shipped is awesome.
I got another question though. How are you guys applying that center reverse polarity protection ring?? Press fitted, glued, magic??
Sidenote: sorry if my first post was a little incoherent. I had a half day off in the morning because of the bad weather. Took a lot longer to compose that post than I thought and I ran out of time.
