The Best RV Batteries for Dry Camping

Author: Elliot

The best batteries for dry camping aren’t lead-acid. When you think boondocking in a van, camper trailer, or motorhome, don’t think car batteries daisy-chained together. The DELTA series portable power stations are all-in-one power systems using lithium batteries. There’s nothing to install, no terminals to connect, just plug in and you’ve got power wherever you are.

Dry batteries for dry camping

See ya later lead-acid! Lithium batteries have made wet batteries as obsolete as VHS tapes; there really are no benefits of sticking with those old golf cart or even AGM batteries.

  • Recharges way faster
  • No refilling/spilling/venting
  • 100% discharge (deeper than deep-cycle)
  • Much lighter

Ready-made power source

Instead of figuring out if this inverter is compatible with that breaker using those wires, EcoFlow portable power stations combine all of the needed components in a slick package. Everything from getting power in, storing it, and sending it to your electronics has been fine-tuned by professionals. An EcoFlow portable power station replaces an entire power system:

Works with RVs, vans, and trailers

Plug your vehicle right into DELTA Pro’s 20-amp or 30-amp outlets like it’s a shore power box, or use its 30-amp Anderson Powerpole outlet if you have the right setup. Other members of the DELTA family have 20-amp outlets and can power several appliances at once, but you may need a dog bone adapter if you’re using it as a hookup.

All the bells and whistles

Upgrading from lead-acid batteries is more than just getting a better battery. Here are a few things most 12V battery systems can’t do.

App support

EcoFlow’s screens are already the best out there, but the app takes monitoring and controlling your energy to the next level. Check on how much your solar panels are bringing in, fine tune battery settings, or turn on the AC ports on your way back to the campsite.

Take it anywhere

These plug-and-play batteries aren't fastened down so you can always pull it out of the storage bay and use it somewhere else. Take it to power outdoor events or to rescue a stranded electric vehicle. If you’re not a full-time RV’er, DELTA Pro can be used at home for lowering energy bills and backup power during a blackout.

Charge from EV stations

DELTA Pro is the first battery of its kind to recharge from level-2 EV stations, which are way faster than regular AC outlets. It goes from 0–100% in a little over an hour and a half, so you can get on to that super secret camping spot sooner.

How to compare lead-acid and lithium batteries

Watt-hours vs. Amp-hours

You’ll notice that many portable power stations have capacity listed in watt hours (Wh) but lead-acid batteries use ampere hours (Ah). These numbers are important for comparing how long you’ll be able to boondock or how many appliances you’ll be able to use. Fortunately comparing them is pretty easy: multiply the volts by the ampere hours to get the watt hours. A 12V battery that’s 100Ah has 1200Wh, and three of those connected in series would give you 3600Wh – the same as DELTA Pro.

Depth of discharge

With lead-acid batteries, you’re really only getting 30–50% of the stated capacity because going below 50% capacity quickly damages the battery. Lithium batteries can use 60–80% of their capacity for maximum longevity, even 100% when needed.

In short

At face value the 3600Wh DELTA Pro’s lithium battery is equal to three 100Ah 12V batteries, but really it has a much higher usable capacity. Because you can use virtually all of it’s capacity, it can replace as much as five or six 12V batteries. Still not enough? Extra battery packs can double or triple the capacities of DELTA Pro and DELTA Max.
