Energy Loader

The Energy Loader is a block from the Railcraft mod. This block acts as a link between the IndustrialCraft 2 power network, EU, and the various EU storage Minecarts from Railcraft, like the Batbox Cart and the CESU Cart. By default this will output at 512EU/t. There are several sections to the GUI of this machine. The top left slot is used for charging tools and armor from IndustrialCraft 2. The bottom left slot is used for decharging things and putting their power in the Energy Loader. The right hand slot is used for upgrades. You can use any upgrade from IC2, as well as the Lapotron Loader Upgrade. An Overclocker Upgrade will increase the transfer rate of the energy by 30%, and increase the energy usage by 50%. A Transformer Upgrade will increase the energy output by a single tier. The Energy Storage Upgrade will increase the total amount of energy storable in this machine by 10,000EU. Lastly, a Lapotron Loader Upgrade will increase the Loader storage capacity by 1,000,000EU. Additionally there are two buttons, Hold Empty and Top Off. These buttons are used for controlling how this machine works. Turning Hold Empty on will make carts stop even if there is no power available. Toggling Top Off to on will make the carts wait until they are full before the machine outputs a redstone signal. Below these buttons is a section that says "Rate", this is the rate of the energy transferring.

Usage
Place the loader directly next to a track, with the 3 black dots facing the track. It is preferable to put a Holding Track or a Boarding Track on the block in front of the Energy Loader. Set up an EU-input system for the loader, and place any upgrades you wish in the upgrade slots. Toggle the two buttons to make it do as you wish, and then use a Batbox Cart, an MFE Cart, or a CESU Cart to move the energy from the loader to the cart.
