{{bloc-etroit|text=OK, so you have a project and now you want to power it off of a battery, how do you choose the best setup?

{{bloc-etroit|text=Nous y sommes. Vous avez un projet que vous voulez alimenter à l'aide de pile. Comment allez vous faire votre sélection?

The two easiest cases are the extremes:

Les deux cas les plus simples sont aussi les plus extrêmes:

* '''Is your project very power-hungry?''' Projectors, large sound systems, and motorized projects all draw on the order of amps of current! You'll want to go with lantern cells (one-time use) or lead acid batteries (rechargable). If you are planning to be somewhat 'abusive' to the battery (heavy-usage, running it down all the way) you may want to look at "marine deep cycle" batteries.

* '''Is your project super-small, like an inch on each side?''' You're going to have to go with a lithium coin cell (one time use) or little lithium-polymer cells like the ones used for tiny RC planes.
