I posted this question in the Bicycles forum but didn't get much of a response. Maybe someone here can offer some advice.
I'm adding a 10-cell D-size battery pack to my existing 36v Crystalyte Journey pack. The problem is I believe the original pack is 8Ah and the pack I'm adding is 10Ah batteries. Since I'm adding the pack in series I'm wondering what the downside of the mismatch will be. If this was Lithium batteries I know that would never work, since Lithium can't go below a specific voltage without damage. I'm thinking the 8Ah batteries will just become depleted sooner than the other batteries, and I suppose those batteries won't last as long. I don't know if this will be a major problem though, since most of my bike use is for short hops and I charge immediately after use.
