Total Newbie on a budget

That ESC won't work with batterydrills.
It's a brushless ESC, ment for completely different motors. Also, even if you would change the motors to brushless motors, that ESC can mak'em turn in 1 direction, not reversing.

Also, ESC's ain't something you should be skimping on. It is rarely a good ESC will fail you.
The Ranglebox/BotBitz 30A or the way stronger TZ85a's are the primary choise in the UK.
There are dedicated Featherweight 2 channel ESC's
Robot Power Scorpions is a known quantity, but expensive .
The German IBF 4.5 is quite a bit cheaper, and is rock solid. Even if the amp rating looks a tad low.

The battery, too expensive for what you want/need. This delivers more volt (11.1 compared to 7.4) for a way cheaper price
