Unbelievable performance for the price

Unbelievable performance for the price. I have 5 total in my RV. 4x in 48v configuration for my EG4 12000XP and a single 12v to run the smaller 12v loads I did not convert to 120VAC. Both systems have operated flawlessly.

Great quality 12v 314ah battery

I use this battery for my RV’s power system, and it’s been fantastic. It holds a charge for days while boondocking, running my lights, fridge, and water pump without any issues. The build quality is top-notch, and the BMS keeps everything protected. The size is perfect for the battery compartment, and it’s much lighter than the old lead-acid it replaced.

Great Batteries

Exactly as described. Only have had them a few weeks and have not installed in my RV but I have been playing around with a couple of different 400w solar panels and they are charging well

Customer service

Had a problem with the battery not charging but after contacting the customer service, they guide me through the process and after that everything worked out great. The customer service is excellent and the product. I’m using it for last two weeks now it’s working great thank you for standing behind your products Not like the other brands.
The battery itself is heavy duty and they are selling it for a great price

Great battery for our Camper.

Great battery we camped all summer on it. We don’t have power at the lake we camp at, And we never came close to running out of power even with the electric only fridge. We were still able to make coffee in the morning with a keurig. The 400 watts of solar charges it back up quickly.

Perfect match for customized solar system

Needed special capacity for my customized solar energy system, this 314Ah fits perfectly. Compact structure saves installation space, low self-discharge for long time storage. Performs consistently in all weather conditions, highly recommended.

Exact true capacity, reliable performance

This 12V 314Ah battery is exactly as described with real marked capacity. Well packaged and arrived in perfect condition. Charges fully quickly, maintains stable output under daily load. Great upgrade for traditional lead-acid batteries.

Heavy duty build for long time daily use

Very solid and heavy-duty construction. The shell is thick and anti-collision, suitable for fixed installation all year round. Steady voltage output when running multiple electrical devices, no heat issue even after long hours of working.

Reliable and Compact!

Have been using the battery 314Ah as an emergency power station for almost 8 months now and I've had zero issues. Battery life lasts me a couple weeks with steady use with solar, and has proven to be an excellent value for the price. These are compact batteries and not all that heavy, so they're easy to carry/organize. The posts are an M8 style and come with short/long threaded studs to meet any need you may have which make them easy to setup! Would definitely purchase again.

Stable Voltage All the Way

This 314Ah has been in my RV for almost a month now. Powers the fridge, lights, water pump, and a small inverter very smoothly. With my old lead-acid batteries, voltage would drop after half a day. Now it stays steady the whole time. Lighter than I expected too, I installed it myself without any help.

Used in my RV for a month, very happy with the range.

GOOD

The Battery was shipped to me here in San Diego Ca, very quickly and was well packaged. I will only use the deep cycle battery for emergency power backup along with a large Solar panel etc. We plan on getting a second battery as soon as I'm done testing my full backup solar electrical setup.

Lucas Davis
Plenty for Weekend Camping

Bought this to replace my old smaller battery. The 314Ah gives me way more range. Went camping for a weekend, used an electric kettle and a small rice cooker, still had plenty of charge left when I got back. Charges quickly too, and pairs easily with solar panels for topping up.
