I want to order some Keystone 18650 single battery sleds. I'm still trying to figure out which of the three types that I need:
1042 Single 18650 Cell Surface Mount - phospher bronze
1043 Single 18650 Cell Thru Hole Mount - phospher bronze
1044 Single 18650 Cell Solder Tab Mount - stainless steel
Also, since Keystone says they are for "batteries with circuit protection", will my non protected batteries still fit snugly enough to make good contact, or do they make different sleds for non-protected batteries?
Thanks,
Randy
