2 Packs 12V 300Ah Lithium LiFePO4 Battery,200A BMS 3840WH Rechargeable Lithium Iron Phosphate Battery 15000+ Deep Cycles for Solar Energy Storage,Backup Power,RV,Camping

We purchased this battery to replace the lead acid battery our camper came with. It is a big battery, but I was able to fit it under the bench in our camper where the rest of the wiring was. I was able to go two days of boon docking while not trying to conserve battery life before charging and never got below 40% battery life. We were running our fridge and hot water tank on propane (both still use a little electricity to light), two vent fans, lights, at night, the radio, charge or phones, my dad's hearing aids, apple watches, air pods, and the water pump.I watched some YouTube reviews on other size battery's this company offers, and they all seem to be built really well. This brand has ender temp and over temp protection that actually works. I bought this to use, not review so I will not be tearing mine apart to confirm this, but I watched multiple videos from multiple sources. I do wish I had the extra money to buy the 300-ah battery. It is smaller and has a larger capacity, but for $268.00 I couldn't pass up this deal. If I decied to upgrade again, I will probably buy two of the 300-ah battery and move this one to my popup.

Good power. Rate of charge good IF you buy the right charger. Functionality good. Weight as expected with very nice handles. Terminals very easy to connect to. Using it daily for 30+ days without an issue.

So far this battery has exceeded my expectations. It is able to run the 15,000 btu AC unit on my camper for at least an hour and a half in 90°F weather in a pinch. it will run whatever you need if you have to rely on a battery, it is quit powerful.I installed a Victron inverter/charger and solar panels for off grid camping and with this battery, I'm able to enjoy camping without a generator unless you need air conditioning for more than an hour and a half.

So far so good I think it’s a great battery for the money. Completely discharged the battery running a small cube refrigerator in my trailer and the battery lasted about 80 hours. This was running through a 2000 watt inverter I wired into my 2022 Crossroads trailer. The trailer was equipped with an automatic detector converter that charged the battery back to full charge overnight. This will allow me to run the refrigerator while traveling and stay off the grid for a couple of days.

Will Prowse (YouTube) reviewed a Dumfume and said it was well built so I figured I would take the chance on this 300AH and I’m glad I did. It has been working flawlessly for months now and powers everything in our camper including a 2000 watt inverter running a microwave, lights, heating blanket, etc. Recommended!

Lifepo4 batteries have become surprisingly affordable in the last couple years and Dumfume is one of the brands leading the pack. I was amazed at how much power this thing holds. My wife and I were able to camp 4 days on 500 watts of solar and this battery with NO generator, so that's pretty awesome. It's always risky buying a budget product from a new brand but I can say these sellers stand by their product. While I did end up returning the battery because of a balancing issue I have a feeling this problem is fairly rare and I would definitely consider buying this brand again, especially if they add bluetooth. Most importantly, they stand by their product and work hard to make things right for the customer. This brand is a great value, in my opinion and if you are familiar with Lifepo4 you know what I'm talking about.
