Looking for a 21700 with both +/- on the same end.

I have a headlamp, from Home Depot, that that has both +/- on the same end. I am looking for replacement batteries at a decent price, HD has them for $24.99.

You can make it yourself with correct size metal washer connected to negative terminal with metal strap and glue it with insulator to positive of battery then wrap it with heat shrink.
Streamlight Strion has similar battery but uses 18650.

Nitecore produce some 21700 batteries with the +/- at the same ends, you'd have to check the dimensions.
