As usual with PQ batteries, this battery exceeds it's specs, is a true performer, and exceeded my expectations again. This is my second 300AH/12.8V battery and I am standardizing on these for my system.

I bought one 300ah battery at first. Thought i had a problem with the battery. Powerqueen support is the best i have dealt with. Usually I am somewhat of a annoyed person. Powerqueen took ownership of my concerns and put me at ease. So i bought another battery. I have plans to buy 4 more 300ah batteries. These batteries are incredible!! They last a long time and have slow discharge. I am running a 1000w on roof in serial. Victron 250/70 and not happy with the Renogy inverter. Anyway looking for a sale from powerqueen to get more trying to get 6 12.8v in parallel.

This is our 4th battery from Power Queen. We absolutely love them!

I bought one 300ah battery to build a solar generator. It's done a great job, Now I've bought 8 more to power my house. Shipping was much faster than expected and every email I sent customer service was replied to in one day. I would like to see them add a communication port to each of the battery BMS so they can communicate with solar charge controllers but otherwise a great buy.

Off the grid solar power, AGM batteries failed after 3 years. Installed Power Queen Lithium battery replacements September 2024, 48 Volt 300AH string). Looking forward to 10+ years of battery life,
The system remains powered 100% of the time with a very small load and the facility is used 6 to 8 times a year with much higher loads (4 KW peak). Set solar controller bulk / absorb / float charge at 58.4 Volts. Product manual does not specify float charge, I may lower the float voltage to 54.4 volts.

Batteries are new and work well with another brand of 12v 300 amp…plan to purchase another set for a total 6. Operated in the 24 volt configuration

Using the Power Queen 300 ah in conjunction with 2 other 300ah batteries as an emergency backup for refrigerators. Using a 3000 watt power inverter. Using a 100 am power max PM4-100LK charger to charge all three in parallel. THE POWERQUEEN came with near a full charge. This battery is a hot one.

I love my power queens can't wait to get my 4th one. I'm willing to do any advertising of your products
So next spring when my build gets finished and everything is fully operational. I will be showing off my power queen system. Thanks

The first one was so awesome I had to get a second one and it's just as awesome as the first, I can't believe the power these batteries have and how long they keep going, I'm, running my whole house off of just two 300 amp hr batteries, I'm planning on ordering two more to have for those cloudy days when the solar just can't keep up

Just recently got this 300AH battery. Still putting in the time of use. It is my RV house battery. It gets Abit of charge by alternator & there is now a 300 watts PVP on my roof. Last night & today had a hurricane passing by so not a lot of sun.
Will be testing reserve then see if full day of sun tops it off to float tomorrow. So far it is a great battery.
Chris
Seems like an excellent RV battery.
Just put it in place & working.
Will know more in the future.
ALAN P.
Very excited about using this battery. Every review on it I’ve seen has been excellent. The instructions and info given with the battery was excellent. Thinking about getting another one.
Stephen D.
Love this guy… for a 300ah battery at this price point you can’t beat it. I should have went lithium a long time ago.

Put this on my RV trailer to replace two AGM batteries lighter and twice the power. Love it.
Anthony m.
Love the capacity of this beast, using it with a 1000 watt bougerv inverter and a voltworks 2500 watt. Runs both perfect not a problem, charging with 720 watts from 4 bougerv 180 watt panels to a victron 100/50 or a 20 amp ac charger. Waiting on another great sale to add to the already impressive run time.
Dwight H.
Works perfectly. Love it
Scott S.
Greatest upgrade to my rv to date.
William D.
The wife and I are semi truck and trailer. When we retire will be putting the batteries in our trailer. We have two batteries now will be getting two more to complete our system. The build will go in this summer. Thanks Bill and Diane.
Michel L.
The batteries are well built
Very solid, terminals are strong
Versatility to connect many Series and parallel is a big advantage for expansion
But the best thing is the outstanding tech support and attention to customer service is outstanding!
And that’s very important to all of us !
GREGORY W.
Love it! the 300Ah I have had for 3months now, hooked up with 8 100w solar panels with a 150-85 victron Mppt. Just bought another to make a 24v system now.
