Wooo,
First problem you had was probably running 12v drills on 24v....that€™s why they were unreliable. Don€™t make the same mistake with your gold€™s. The most you would want to over volt a 12v gold to is 14.4v. As ploughbot runs his 12v motor on 24v in his lifter and after about 4 lifts its red hot. If you must use 24v go for the 24v version of the gold motor....However remember you may need some serious size battery€™s as these motors are known as being un-reliable, good luck!
