Parallel or Series

[whosgregm]

Which would you recommend for battery connection? I bought 2 - 12 volts LifePod Lithium batteries. I had the old ones set up in series connection however I’m hearing from friends that parallel connection is best for RV. So I’m turning to the experts in the forum. Appreciate the assistance, my fellow RVers.

They would have to be connected in parallel. Negative to Negative and Positive to positive. Wiring them in series would turn them into 24V
Unless you mean the batteries are 6V then series would be correct.

Wire 12 volts parallel ONLY & 6 volt in series ONLY.
Your rv power sources are 12 volt DC and 120 volt AC ONLY.
If someone told you to wire 12 volt batteries on your rv in series DO NOT take their advice for ANYTHING else, they don't know what they're talking about & going to cause you lots of grieve & expense.
