mix wet and dry cell?

[illestVillian]

Can I keep my stock battery up front and run my 0 gauge to my new xs power xp2000?

[noobslayer77]

yes. but if you don't have the 2 isolated, the battery up front will pull voltage from the xp2000 when the car is off, trying to seek equilibrium. The voltage will see-saw back and forth and lower the charge of the agm over time. This is what i have been told.

pretty much what I understand

[_paralyzed_]

It can be done, but as mentioned above, the see-saw thing. An AGM has a higher resting voltage than a wet cell. One of the batteries will have a shorter lifespan than normal when mixing batteries, either you over charge the wet to keep the dry happy, or under charge the dry to keep the wet happy.

That said, I've seen batteries last over 5 years. You could maybe get away with it for 1, 2 years or more. It is a compromise, and not the best way to do things.

Will it work? Yes. Are there better ways? Yes.
