I love what this mod offers, thank you.
The accumulator can be seen as a battery but transporting it isn't an option with that so;
Could you happen consider adding batteries?

How it works is by;
-Battery runs out depending on machines load of usage.
-Tiers of batteries holding more charge.
-To much demand/stress whilst activated can crack or blow up. This one is debatable just an idea.
-Has a switch toggle on the side of the battery
-Connects with your electric motor to send out power
-Sophisticated/expensive recipe
-Stack size of 1
-Block size of 1 or 1x2 for better types.
I mean pretty much what a battery is.

I think this additon works well in conjunction with create and this mod, not too op just useful enough as a quick power source than setting up a steam engine or permanent power station, as well as powering contraptions outside bigger networks, ex. vehicles, cannons, simple moving contraptions, I'm sure it's use will be found elsewhere than that I mentioned.

Thank you.
