About:

LC Tech is an expansion mod for Lightman's Currency that adds new Fluid & Energy Traders to your game.

Features:

Adds 2 new in-person Fluid Traders to the game, with 1 & 4 trades each.
Adds 4 fluid tanks (Iron,Gold, Diamond, and Netherite Tank) that can hold 10/25/100/200 buckets respectively (can be configured). Will maintain their contents once harvested, and will automatically combine when stacked on top of each other (assuming non-conflicting fluids are held).
Adds 4 fluid trader capacity upgrades that increase the tank capacity of all trades by 10/25/100/200 buckets each (can be configured). Each fluid trader can hold up to 5 upgrades.
Adds 4 Fluid Network Traders with 2,4,6, & 8 trades each.
Adds an Energy trader that can sell or purchase any Forge Energy compatible energy. Customizable to have 1-4 trades (trades can be added/removed at will by the owner).
Energy Network Trader. Also customizable to have 1-4 trades.
Adds 4 energy trade capacity upgrades that increase the amount of power able to be held in the energy traders by 100k/250k/1M/2M FE each (can be configured).
Adds Fluid/Energy Trader Network Traders Interface blocks to allow remote restocking or purchasing from fluid & energy network traders.

Should be compatible with all modded fluids.
Tanks and traders should be compatible with all modded fluid pipes/pumps. I cannot make any promises that their names will display 100% correctly for mods that add fluids whose names change based on NBT data, as I've found that not all mods implement that the same way.
Should be compatible with most modded energies. If not, then that mod does not properly utilize the built-in forge energy api's included within forge.
