Mixing AGM batteries


Recommended Posts

I was looking to add some more reserve to my build and was able to get a deal on a northstar NSB170 (thing weighs like 125 lbs) and I was going to use it with my XS power XP 3000 and D3400 under the hood on a singer 370 amp alternator. Im just wondering if I am going to run into problems by mixing different sized batteries? Should I have used another XP3000 instead?

Different sized batteries are a problem in deep discharge situations like electric cars and solar banks and demos with engine off. As long as you play with the vehicle running and your voltage is up, you should be ok.

If you ever want to fully charge each battery you would have to disconnect them from one another to get a complete charge. You can mix them all day long but you wont get some in the group to fully 100 percent charge, I have a dual bank charger for his purpose. but I am lazy and only do the seperate charges on the night before big comps.
