Big Battery is a mod where you build multi-block structure battery to generate RF power.

You can make very huge structure ( max is set to 100x100x100 in the config file, you can change it up ) that will generate very huge amount of power. This mod goes in the same direction as Big Reactor with a lot more modularity (lot of diferents materials and combination ) and power generation potential.

Like real chemical battery you'll need electrodes and electrolyte made from differents materials, each materials have differents properties, some material will last very long but offer less power generation potential, as other materials will do the contrary. Its up to you to fine the right balance with what materials you have in hands.

You can use interfaces to handle materials refilling of your battery. Interfaces handle hopper, item or fluid pipe from other mods.

Craft BigBattery manual to learn everything ( Book + Steel ) ( Steel = Iron in furnace ).

For Mod packs : Materials are easily configurable in materials.xml file.
