Mod Guide: Basic Voltage modding for everyone

To make some things easier, I've decided to make a basic guide to voltage mods with electronic blasters. I'll tell you what you need and should be careful with.
For all Voltage mods, I use unprotected Lithium-Ion Trustfire 14500 3.7V batteries, which you can get either from here or your local electronics store.

Also be completely sure you have a Lithium-Ion Charger (Yes, they need special ones), otherwise your batteries might even explode. These rechargeable batteries are good, because they have the same size as an AA battery, but higher discharge rate and voltage. With these, you can just replace your AA's in the battery tray with your Trustfires.

Trustfires are not essential, you can just as well use RC-Battery packs or else. 

Sometimes, you want only a little higher voltage (Picture: 8.4V), and not all battery slots filled with Li-Ions. This could be either because you think the motor is too loud with the maximum voltage (which is often my reason) or in stock condition, the Thermistor blocks any higher voltage. In that case, you can just put some connection in the slot to bypass it. I only use isolated copper cables, but for better safety dummy batteries can also fit in.

Full-auto blasters only have space for C size batteries. Then, either battery packs (like in the picture) or AA to C converter shells come into action.

Now that you've been informed about Voltage mods, you're good to go!
