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.

  • 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

  • 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

  • New Purchase Review
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

  • Absolutely Impressive
Size: 1 Pack Set name: 12V 300AH (APP View)
Wow, truly impressive battery. Running 4x100 watt panels and the voltage does not drop. I run all my stuff during the night and still have a lot of power when I wake up. It's fantastic.

  • 12 volt for my RV’s fridge and more
Size: 1 Pack Set name: 12V 300AH (APP View)
I’ve seen different brands after watching different videos. This matches the size for the space available in my rig. 300Ah, maybe big enough for me. I mainly need it for my 12 volt fridge, and some lights in my rig. I don’t need anything bigger for now, but if I do I would get the same brand. The app works flawlessly, it updates automatically. I just wish it comes with longer nuts and bolts, probably they want you to use a bar to connect multiple cables, it makes sense. Yes I highly recommend this brand to all. It comes with years of warranty, I hope they really stand with their product. High quality so far. Pricewise, on the higher side. It matches the agm 12 volt I replaced. Compatible to my rig, perfect to be exact. ... show more

  • Good battery, great app
Size: 1 Pack Set name: 12V 300AH (APP View)
Great battery. No over charging. They have an easy to install excellent phone app. If I’m standing within Bluetooth range of the battery, I connect to it, and it gives me the full specs; it’s charging rate in V and amps and the total percentage of charge.

  • Great battery.
Size: 1 Pack Set name: 12V 300AH (APP View)
So Far, so good. Bought for my new RV. pre charged and then installed into double battery box. Had to pad each side until I find a good replacement for the battery box. Works well with the onboard converter and 200w solar. Keeps 12v Magic Chef frig/freezer at needed temperature with about a 20% drop overnight (It's hot 95-100 f here, so the fridge is constantly running to keep up. I do have an additional solar panel I will use on a longer camping trip to watch the recovery process. ... show more
