Summary

Dual 26650 Battery Sled for Hammond 1590B enclosure.

Bottom of the sled wraps around the screw posts of the 1590B enclosure and has a protective barrier to make sure the terminals can't short against the enclosure. Also has a channel on the bottom to route the bottom wires to the top of the sled.

I prefer to "top-mount" the battery clips, I'm worried that when bottom-mounted the downward force when inserting the battery could, over time, cause the clip/terminal to slide down and short against the enclosure.

Uses the Keystone 228 for the positive contacts and the 209 for the negative. Always remove the battery clip/terminals from the sled when soldering your lead wires!

Do you know the amperage rating for the contacts? I'd like to adapt a 4 cell version but am a bit concerned with pulling 26A through spring terminals.

I don't, but I'm sure the contacts can handle it. I thought "spring" contacts were the ones with an actual spring... these are a solid metal.
The heat that would be generated by drawing more amps than the contacts could handle would melt the sled and the solder long before the contacts fail.

Thanks, and as I hit send I also realized, I'm talking about series so only voltage goes up so I should remain within the manufacturer's spec.
