But I was so busy sorting out the holder for the battery and did not NOTICE that the + end was a little smaller on Material as the battery clips i used did not REACH the POSITIVE clip ?...

Also I notice my battery _ spring was a little soft so I shortened the whole box's by 1 -2mm
and ADDED a + sign to denote the Thiner end

I also wanted a CHARGER so @ £8 I bought 2x of these

I Just wanted a holder to house the batterys in as when we go Camper-vaning some times our pitch with Drive-away awning and yes you guessed it every one TRIPS over the guy ropes.
So these battery holders will accomadate the 18650 batterys and provide some lighting ...
I'm goin to use an old Solar Garden Lights with the new COB LED's (x20) and later on will make a Holder for them as well
