I’ve covered this topic a few times on the forum, but never here on the blog. Before the latest additions of the OMG line, it wasn’t something that really needed to be covered. Every battery has three ratings, nominal voltage (in the case of lithium cobalt and lithium manganese 3.7v), milliamp hour (mAh or milliamps per hour), and c rating. Most people are somewhat familiar with the first two, but not the last (c rating).
