Casita AGM battery Amp Hours

[bobwadeguitar]

Checking my facts: the AGM upgrade Casita offers is 190 amp hours. Does that sound right? THX

Might be true, but doesn't sound right, since an AGM battery with double the amperage would also be double the size and weight. I see DEKA has a 12 volt/200 amp hour battery, but it weighs 129 lbs. They also have a 190 amp hour battery, but it's only 6 volts.
Might be best to call Casita to confirm since I don't see the description on their website.

Info I found is that Casita offers a optional Group 31 AGM battery. Most Group 31 AGM batteries range from 95 Ah to 125 Ah. A 190 amp hour AGM battery would weigh close to 200 lbs! You would need a very large alternator to charge something like that!!! Something like the alternator from a Ford F350 Super Duty pick up!

I purchased the Interstate AGM battery from Casita in 2019 when I purchased my trailer from them. As I remember, the battery is rated at 100 Amp Hour. Of which you can only use 50 amps of that power without damaging the battery.

My AGM battery weighed 71 pounds. There is no room for a much larger battery in the battery compartment of the Casita. I have since gone to two 105 amp hour lithium batteries that weigh approximately 41 pounds each. They can be discharged to 10 percent of their rated power. So I went from 50 amps of available power to over 180 amps of available power. I installed the batteries in the compartment located over the driver's side wheel well. This locates the batteries very close to the Casita power panel.

Thanks - that seems more reasonable. I'll probably go with their AGM for starters and maybe switch to lithium down the road.

Thank you - that seems more accurate. I couldn't find one searching online that seemed to match up.

Thank you - helpful info!

Something that hasn't been mentioned here, is that you can get one of those AGM batteries elsewhere for less cost than what Casita charges for it. My next question would be why do you even feel that one of those would even be necessary to begin with? Just sayin'.
And I will add, fwiw, that I've always used, and never had any trouble with, regular plain old cheap lead-acid batteries. I'm 70 years old, and I've been using them successfully for more years than I can remember.

Also, Casita charges extra for the AGM battery upgrade, but doesn't give you a credit on the standard battery they deleted.

So basically, you're getting double-charged.

Suggestion: Get the standard battery, and upgrade it when it eventually wears out.

90 usable AH in the same maximum G27 battery space.
LiPO4 batteries have very little voltage drop over the discharge cycle and float at 13.2 volts.
Lead Acid batteries are a thing of the Past.
