Newbie question on this: Just picked up an AGM 25-384 and will be running an Anker power pack for it. Is there a maximum mAh that they can use? I have several 10,000, but also some larger (26,000 I think?) is that too much juice or can they handle it? Also do you have to remove the Cr123 batteries when you use external power? Really trying to not fry a $2000 unit by mistake.
