Battery upgrades

Has anyone upgraded the battery system in their FR3? If so, what did you do?

I don't have an FR3 but I did upgrade my batteries to a pair of 90ah deep cycles.

I need to learn more about these battery systems and how they function. Perfect source for me. Thanks.

The only upgrade I"ve seen is someone went from 2, 12V batteries to 4, 6V. A new battery mounting plate would have to been made in order to hold the 4 batteries.
Hope this helps.

I neglected my 2015 FR3 30DS stock batteries, mostly because they are out of sight out of mind. mine were not only low on water but we're also dead dead dead... And for a long time. I yanked em out, cleaned em up, filled with distilled water, and used my buddies ship to shore charger. I nursed these battery's for 3 days with over night rests and I'm happy to say I've got them back and hovering around 78%. Not bad for the long dry dead period of about 6 month with most of that time being winter.

Just for knowledge sake, the portion of the plates that were uncovered in acid, are now dead. If you're only using them sparingly, you probably won't notice it, but if you dry camp much, you will. The test would be, put a load on them from the 78% you believe them to be maintaining, and then after a short time, re-test. That will give you some idea, how much functional utility your dealing with.

When I got my 30DS, I added solar, and when I did that, I removed the original 2 - 12V house batteries and installed 4 - 6V batteries. I did have to install another battery holder for the extra batteries. The reason being that from what I've read, battery longevity favors the 6 Volt batteries. My understanding is that a major cause of deep cycle battery failure is the shedding of active material from the battery plates and the 6 volt batteries have thicker plates. I'm no expert on the subject, but that's what I ended up doing.
