The next step up is 2x 300 Ah Essentials. Call me crazy, but we're lovin' our 900 Ah with these great features. 😎

I discussed this with Ken, I think this is what I will do too.

You cannot go wrong with Epoch, another brand that’s also getting good reviews, and is on Will Prowse’s approved list is WattCycle https://www.wattcycle.com/products/wattcycle-deep-cycle-rv-battery-ad

Good choice Mike. Ken would have his installed already if it wasn't so cold in the east!

They better get a handle on this or they may have some rough times ahead - true or not.

I think that they have been in that zone for quite some time now.  I am suprised that we have not seen more on this.  Glad I don't own any Dragon Fly stock.  Sad that so many of us are, or will be impacted by their design, marketing and now warranty decisions.

but with 900 Ah I'd have to run our A/C, our Air Fryer and run a power cord to another RV to run their A/C to get anywhere the 600A of continuous power (2x for peak use) the spec of these batteries

I know you are just joking.  But let's not toss that glove as someone may try it.  I think our 4/0 cables and lugs would have some concerns if running them at 900 amps. Not to mention our fuses.

Checked AI and "it" agrees.

$2400 to do so, plus likely mods to the cables and fusing...   OUCH............

We installed two Epoch 105 AH replacing two 100AH BB batteries on Ollie. We don't have factory solar charging and only have an onboard Progressive Dynamics 45A Lithium charger. The BB worked nicely with this setup.

The Epoch 105AH batteries are a little smaller physically and lighter than the 100AH BB batteries. I like the carry handles on them, too. The new Epoch batteries with the carry handles are easy to install and remove on Ollie. I removed them in less than 10 minutes when I put Ollie in storage this winter. It will take a little longer to install them later this month. Really like the Epoch app, too.

Edit: I looked at the Epoch 105AH link in your post and thought you were installing 105AH, what ever size is used, they are very nice batteries.

@rideandfly I also have the same 45A charger it put in a couple years ago. I’ll wait until these newer LifeLine AGMs get a bit older. So far they’ve been more power than I need, but will retire in December so camping life style will change greatly. 
 

Keep us up to date.

Not kidding, just stating that each 300 Ah Essential can take 200A in our out but of course when you run multiple units in parallel, agreed there would be other limiting factors. For example, the Victron MP2 can only charge 120A and requires a 400A fuse which is the max DC in it can invert! As mentioned before, you’d have the run the A/C, microwave and more to hit that limit. As you pointed out, sane 400A limit on the 4/0 wire.

There are at least a half dozen Oliver owners that have made this purchase, at this price point, two more with Ken and soon Mike. But don’t spend $2400, wait for the 15% off. I think it’s worth it. I spent $1800 on 600 Ah summer 2024 and $1,020 for the 3rd Epoch 300 during Black Friday sales. So my 900 Ah total is$2,820. Isn’t that close to the cost of three 100 Ah Battleborns for 3x the Ah?
