Electron charge pack (Fallout: New Vegas)

Electron charge packs (ECP) are a type of ammunition in Fallout: New Vegas.

Characteristics
These small electron batteries are used as ammunition by several energy weapons.

Weapons using this ammunition

 * Arc welder
 * Gatling laser
 * Sprtel-Wood 9700 (GRA)
 * Tesla cannon
 * Tesla-Beaton prototype
 * Laser RCW
 * Elijah's jury-rigged Tesla cannon

Recycling
After firing, there is a chance that spent electron charge packs will turn into drained electron charge packs. These are automatically turned into a miscellaneous item and placed into the player's inventory. Drained electron charge packs can then be recycled back into usable electron charge packs at a workbench.
 * See: comparison table for chances of drained electron charge packs being produced for each variant of electron charge pack.

Conversion
Electron charge packs can be converted into, and from, other energy weapon ammunition types (i.e. energy cells and microfusion cells) at a workbench, with the appropriate Science skill.
 * Conversion (type)

The player can also pool charges from good packs together to make more powerful variants, which improve damage and bypass more enemy DT but burn out weapon components faster.
 * Conversion (variant)

Electron charge pack, bulk
Bulk packs are less potent than the standard version, but are cheaper to purchase. Weapons firing bulk electron charge pack ammunition degrade at a rate of 15% less per shot compared to standard electron charge packs, at the cost of dealing 15% less damage to the target and no DT penetration ability.

Electron charge pack, over charge
An electron charge pack that has been given a bit more charge than the standard electron charge pack. Weapons firing over charge electron charge pack ammunition take 50% more damage per shot compared to those firing standard electron charge pack ammunition, while dealing 25% higher damage to the target and penetrating 5 DT.

Electron charge pack, max charge
An electron charge pack with its energy condensors charged to their limits, making it more powerful but also necessitating increased maintenance. Weapons firing max charge electron charge packs degrade at a rate of 150% more per shot compared to those firing standard electron charge pack ammunition, while dealing 50% greater damage to the target and penetrating 10 DT.

Electron charge pack, optimized (Vigilant Recycler) (GRA)
Added in Gun Runners' Arsenal, this sub-type causes 30% more damage, penetrates armor more effectively, and weighs less than the standard electron charge pack. The only drawback is a 10% increase in weapon degradation. It requires Vigilant Recycler and can only be crafted at a workbench. This type of EC pack is superior to Overcharged packs.

Notable locations

 * Hidden Valley bunker. If you gain accepted status or higher with the Brotherhood of Steel, you will be approached by a BoS initiate telling you they have placed recycled ammunition in a box at the bottom of the entrance stairs to the L1 area. The box will be replenished randomly with electron charge packs, microfusion cells and small energy cells whenever you enter L1, giving a continuous supply of energy weapons ammunition.
 * Occasionally sold by Cliff Briscoe.
