I know it's the same battery. I read another forum post where someone said the battery firmware would update on the battery due to a different drone. But what if I share batteries with a P3S and a P3P? I'm thinking of upgrading to the P3P but my son will still have a P3S and we have four batteries to share between the two of us. I go a lot of places without him and I'll use all four batteries myself. Will I not be able to do this anymore?
