What gauge wire on this? Looking for 10 gauge.

The 25 ft extension is 16 gauge, and the battery harness is 16 gauge. So not really a guess that it would be 16 gauge. No way would it be 10 gauge.

is this the same as the mc4 extension cable if i want to run it from my controller to the battery

It is simply an 2 prong 25' extension cord with so you can extend the length (distance) way from where ever you plug it into what you wanted to extend.

Can this cable be connected to a 12.5' cable to make an extra long extension?

Technically yes it can. However I can't say what the extra resistance will do to the performance. I have this connected to the already long Battery tender cable and it charges my ATV battery just fine.

Will these work with the Batter Tender Solar chargers?

yes this will work, have a 10 watt solar panel works just fine
