The battery can discharge at 500A for 5 seconds and can discharge at 350A for 30 seconds. PowerUrus Battery Delivers Peak Performance Beyond the Rest!"


Multiple batteries can be used in parallel. By connecting several batteries with communication lines, they can discharge simultaneously. This perfectly addresses the issue of uneven discharge among parallel batteries that can lead to cell damage.
When multiple batteries are used in parallel, connecting the communication lines can ensure that all batteries are discharged at the same time.


The battery and inverter are connected via a communication line, which makes the power output more stable and perfectly protects the battery from failures caused by overcurrent.
1. Red line connects battery-MPPT, silver bus connects in series in 5 seconds;
2. Green line connects inverter, plug and play;
3. Blue line solar panel-MPPT, automatically adapts to MPPT controller (conversion rate 98%).Applicable scenarios: villas, shops off-grid power supply, camping emergency, property energy storage, etc.


This battery is NOT suitable for use as a starter battery for cars.
With no acid in the lithium ion battery, you're able to safely mount in any position. This makes LiFePO4 batteries perfect for RV, campers, travel trailer, off-road and off-grid applications!

The battery itself seems to be working as intended. I’m using it as a battery backup for our home aquarium and it provides much longer run times than a conventional UPS.
This thing is a beast. I’ve been using it to power my setup for gold prospecting trips, and it runs my 4700 GPH bilge pump all day with no problem. Holds a charge like a champ, and I’ve been impressed with how consistent the output is.
I just purchased a 300ah battery from this company. I have it installed in a camper van and will traveling next week and will get to test everything out, I have this battery connected in parallel to 2 -100 AH batteries which gives me more than enough power to run my AC, frig and lights and fans and a tv until my solar recharges everything, anyway I would highly recommend this battery for anyone looking for a larger battery other than 100Ah batteries.

I rarely write reviews but I am so impressed with this battery. I went back and forth on buying this battery… price point was so high for what you get but I finally ordered it… and I’m glad I did. Came very nicely shipped, mine has 320ah, and the BMS connected immediately to my phone with no issues. The build quality seems excellent.
