Features
- BUILT-IN 200A BMS & Low Temp Cutoff Vatrer Power deep cycle battery has built-in 200A BMS to protect it from overcharge, over-discharge, over-current, and short circuit with excellent low self-discharge rate. With high temp cutting off prevents charging over 167 F (75C). And Low temp cutoff protection prevents battery damaged in low temperature environment.
- Advanced Lithium Iron Technology300Ah lithium battery manufactured by Automotive Grade LiFePO4 Cells with higher energy density, more stable performance and greater power. Excellent cycle performance, fast charging and discharging, charging efficiency up to 100%, and high output power. Without memory effect, no matter what state the battery is, it can be used as soon as it is charged. Supporting expansion for up to 4 series & 4 parallel and suitable for electric energy storage.
- Exceptional Longevity & Lightweight Our LiFePO4 lithium iron batteries provides 5000+ cycles compared to 300~500 cycles in lead acid battery. The service life of LiFePO4 batteries is 8 to 10 times than the standard lead-acid batteries. Helping to minimize replacement cost and reduce total cost of ownership. And the weight of the lithium iron phosphate battery is 30% lighter than the lead-acid battery of the same capacity, so you can carry it more easily.
- Safety & Unlimited Solar Energy The stable Lithium Iron Phosphate chemical structure makes LiFePO4 battery not burn or explode even at high temperature, short circuit, impact and drop. Highest-level safety based on UL Testing Certificate for the cell inside the battery. And it does not contain any heavy metals and rare metals and is more energy efficient, clean, green charging , which called green battery.
- Multi-Application With no acid in the lithium ion battery, you're able to safely mount in any position. This makes li-ion batteries perfect for marine, RV, campers, travel trailer, and off-grid applications!
- All-in-One Energy Storage & Starting BatteryThis versatile battery integrates the functions of an energy storage battery and a starting battery into one, eliminating the need to install and maintain two separate batteries for your RV, off-grid solar system, boat, etc. It not only saves valuable installation space and reduces your costs significantly but also delivers reliable starting power, while efficiently storing electrical energy from solar panels or generators to provide stable power for your electrical appliances. One battery, dual benefits, making it the most cost-effective and convenient choice for all your power needs.

Just purchased this battery and after fully charging it, I put it in my RV trailer and we Boondock for five days with a 200 W solar panel and with my mini fridge going plus lights going and a fan all week. My battery never went below 93% and that would never happen with the other batteries I had before this I was constantly gone below 50% while camping. Definitely worth the value.

Early days but the 300ah without self heating appears to be a good choice for warmer climates where cold battery temps aren’t an issue. However, note the size is a bit irregular. Not exactly group 31 or group 27 so it was difficult to find a battery tray or box that fit. But I did find that the NOCO BG27 battery box fits perfectly.

I more then like this battery . Customer service bent over backwards to help me set up an older mppt charge controller. Finely got some sun to test everything and I'm very happy with the way the battery preforms. This system has continuous load 24/7 and the 300amp battery has not failed in the middle of the night yet. We are in low light season so if it works now I have no worries as the sun light will get longer. The lifepo4 battery seem to charge quicker then lead acid which means I can charge more batteries with the same wattage solar panels. I have included the settings for the mppt charge controllers. One thing , lifepo4 batteries don't need a float or equalization charge. Unlike lead acid that need a trickle charge to stay topped off once a lifepo4 battery is charged, that's it , done. It could sit for a year and still be charged. If you can't stop the EQ or float set them to 13.8 Set the absorption or boost charge 13.8 for 120 minutes. This company seems to really care about their product so the true test is going to be time.

There is a -1.8 to -2.6 drain on the battery at night. Probably feeding the BMS but not sure.

These batteries are endorsed by Will Prowse and Rod Collins - so buying them for my boat was a no brainer. My first foray into Lithium power, looking forward to the results.
