first the battery question. When looking into batteries, I keep hearing about "matched sets", what does this mean and how important is it? I have read that if they are not matched you will not have good performance and I have read here that it really doesn't matter. Regardless I want the amp/hour rating the same for all the cells I use, right.
Charger question: I can fast charge a battery at 2 times it's amp/hour rating. Well if I run 3300 or 3800 batteries, that is 6 to 8 amps. and I need to charge to packs at a time. Is there a charger out there capable of such charge rates?
