Features

  • 2-in-1 Smart Battery: Energy Storage & Starting BatteryThe BMS's intelligent dual-mode control gives the battery two identities. In normal mode, it acts as a 300Ah deep-cycle battery with over 5,000 cycles for backup power. In startup mode, the BMS switches to Power Mode, delivering 1,500A instantaneous current by leveraging the high-rate discharge capability of LiFePO4 cells. Our upgraded technology provides isolated protection, ensuring high-current surges never compromise cycle life.
  • High / Low Temp Cutoff With high temp cutting off prevents charging/discharging over 167 F (75C). And Low temp cutoff protection prevents battery damage in low-temperature environments. The battery can operate from as low as - 4F (-20C) to as high as 140F (60C).
  • Superior Safety with Upgraded 200A BMS Equipped with an upgraded 200A BMS and Grade A Cells. The battery is safeguarded against overcharging, over-discharging, overcurrent, short-circuiting, low/high temperature. A built-in 200A BMS protection plate automatically disconnects the battery when the discharge current exceeds a certain range, ensuring security and stability.
  • Expandable Power Capacity Expand flexiblely from 3.84kWh to a maximum of 61.44kWh. With 16 identical 12V 300Ah LiFePO4 batteries wired in 4P4S, you can easily upgrade your battery system to meet different power needs. Whether for RVs, home backup, or off-grid living, it offers power output from 2.56kW to 40.96kW for various appliances.
  • Fast Charging & Multiple Applications Supports 3 charging methods: solar, generator, and 14.6V 70A LiFePO4 charger. The 12.8V 300Ah LiFePO4 battery can be fully charged about 4.5 hours by a Solar Panel -MPPT (850W), faster than traditional lead-acid batteries. Ideal for multiple applications such as RVs, marine equipment, garden tools, off-grid, and various outdoor electronics.
  • APP MonitoringThe APP can monitor battery voltage, current, power, SOC (State of Charge), and cycle count in real time. This data helps optimize charging (e.g., avoiding overcharging) to extend battery life.
  • ATTENTION: 1. READ THE OPERATION MANUAL BEFORE USE 2. DO NOT TOUCH HOT SURFACE

  • Great purchase
Size: 1 Pack Set name: 12V 300AH (APP View)
Very nice battery - well made case, and very compact for a 300 Ah capacity. Shipping was fast and the battery was packed in highly protective foam and the cardboard box itself was very heavy duty. I'm very impressed. The blue tooth software app is also convenient and useful. You can see the health of each cell individually. On mine, the cells were perfectly balanced and have remained so. I'd buy it again without hesitation. ... show more

  • This thing is a beast.
Size: 1 Pack Set name: 12V 300AH Heating
So far its exceeded all expectations. I installed this in my RV and took it on its first boondock outing of 4 days id say with heavy use running a cpap every night, fans and lights regularly. an inverter for appliances on occasion. Returned home with about 70% remaining with the app stating at my usage rate i'd last another 110 hours. Thats a massive upgrade from the previous lead acid i was using. Its large, i found a group 32 battery box to fit it which was probably the more difficult task of it all. Installation was very easy. It does come with large screw in terminals for various types of connectivity which is great but i used the included terminal screws that keep it as flat as i could for the battery box cover. Charging through my RV does take quite awhile, I had gotten about 140amp hours recovered in 8 hours. The app worked great and is super convenient to pop in and out checking the status, it operates on bluetooth which means it will also work if you are out of service areas which we usually are, it finds the battery instantly and gives you live stat updates. Best upgrade ive made to my camper so far. ... show more

Size: 1 Pack Set name: 12V 300AH Heating
The battery arrived on time, and the item was well-protected. Completed the RV conversion from lead acid to LiFePO4 with no issues. Switched the onboard power station converter/charger to lithium, and the battery charged fully from 51% to 100% in under 4 hours with shore power. The Bluetooth app and connection to the battery worked well with plenty of range. It is not light, but it is lighter than the two 6V batteries it replaced. I am looking forward to boondocking with it next. That will be the true test for how I will like the battery going forward. Vatrer customer service answered the email questions I had with the install overnight, which worked out fine for me. So far, I am fully satisfied. Hope to be saying that years from now. ... show more

  • Solid Battery - Quick Delivery
Size: 1 Pack Set name: 12V 300AH (APP View)
Recently purchased a Vatrer 300Ah LM12300 battery for my fifth wheel trailer to replace my lead acid battery. First of all, the battery arrived 7 days earlier than expected (5 days after placing order). Second, the battery was well packaged and arrived in perfect condition. The battery is the non-self heating version (since I live in Florida) but includes the Bluetooth ability. It was very easy to replace the lead acid battery with the Vatrer battery and just had to switch over from lead acid to lithium on my converter. The battery came 52% charged and immediately began charging via the solar panel. The Bluetooth capability is well worth the few extra dollars and the Vatrer app can be downloaded for Apple or Android from the Google Playstore. I was able to see the current status of the battery and verify that the battery was charging via the solar charger. My future plans are to eventually install an inverter, additional solar panels and adding another Vatrer 300Ah battery. Would highly recommend the Vatrer brand of batteries. ... show more

  • Incredible Battery for the money. Lives up to the Ah rating from the factory.
Size: 1 Pack Set name: 12V 300AH (APP View)
Absolutely fantastic battery. Purchased it as a direct replacement for my existing 2 x Optima Yellowtop's which my boat stereo was draining in under 1 hour. This battery is seriously impressive. It will run the same overbuilt stereo which features a total of 4 x Skar Audio Amplifiers (mix of mono-blocks and 4-channel stereo), 12 x Wetsounds 6 1/2" speakers, and 6 x 10" subwoofers. It power the same exact stereo only taking 12-15% of the total AMP Hours per 3 hours of use. That is absolutely incredible. Very happy with this battery as a stereo battery. Can't rate it for a starting battery, but it's supposedly up for that task also. Apple IOS app also works great. ... show more

Size: 1 Pack Set name: 12V 300AH (APP View)
I bought one for my home power backup system. It worked great so I bought a second one connecting it in parallel. These replace 5 lead acid batteries that were aging and not storing as much power. My solar panels provide around 55 amps to the batteries in bright sunlight. The iPhone application displays battery status clearly. I am very happy with these batteries! ... show more

  • Beast of a battery
Size: 1 Pack Set name: 12V 300AH (APP View)
Well built battery and great performance. Love the blue tooth app monitoring. Wish you didn't have to "connect to bluetooth" (within the app) every time you want to check on the status - this should be automatic (at least provide the option). I am using it to power an inverter in my RV to run the frig and AC (AC for short periods of time ~2.5 hrs) while traveling between camp sites. ... show more
