TECH SPECS
Excited to build out my boondocking setup and these batteries are spec’d well and very affordable. We are full time RVers and hoping this unit works well so I we can puchase 3 more to complete the setup.
At first I'm having doubts, but after I used it, it was amazing. After I fully charge the battery, I'm running my fridge, microwave, water pump, electric stove, water heater all together and I have the power all night. I'm impressed. I just wish that they have a compact size for the 540Ah or 600Ah. I'm looking forward for them to develope more compact size lithium battery
I chose this battery after watching a review by Will Prouse. It seems as solid as he said. Blue tooth is handy. I haven’t fully tested it but will do so next week on our spring trip. So far so good.
Great value for the price
Two 12V 300Ah Bluetooths. Arrived 53% charged as expected. Charged up to cell voltages of 3.6V, the BMS balancer kept all cells within 20mV. Bluetooth app simple, quick, easy. There is a teardown on youtube for this exact battery, the build quality is like a Rolls Royce.
So far it's been great! Battery came in great shape and packaged safely w/plenty of padding. I installed it in a sailboat and haven't been able to put it to the test for a long time, but on and off the charger it is doing a great job! I've kept if off the charger (it is on solar though) for over 24 hours and just minimal loss on a 12 V fridge.
Perfect size with all the amp hrs needed in my situation at tha moment !
Working great! Ease of use.
Great battery
They have been great, so far. Well constructed and they definitely put out some power! When I purchased these, I was under the assumption they were blue tooth, but these are not. Not a deal breaker, I purchased a remote monitor for them instead, but it was an expense I wasn't planning on.
FAQs
Yes, the low-temp cut-off feature ensures safe operation by stopping charging below 32°F and discharging below -4°F, with recovery at 41°F. This protection, combined with charge voltage adjustments, makes it suitable for cold climates like winter RV trips, though it’s wise to monitor usage during prolonged freezes to maintain optimal performance.
The built-in 200A BMS includes safeguards against improper connections, such as overcurrent and short-circuit protection. However, to avoid issues, follow the manual’s guidelines for series or parallel setups (up to 4P4S for 61.44kWh). If unsure, consult the Vatrer support team for assistance to ensure a safe and efficient expansion.
Without solar, you can fully charge the 12V 300Ah battery in about 4.5 hours using a LiFePO4 charger (14.6V 70A), or around 7.5 hours with a generator and a 40A DC-to-DC charger. These options provide flexibility for home or remote use, ensuring you can recharge conveniently based on your setup.
Yes, the IP65 waterproof rating protects against dust and water exposure, making it suitable for RV use in rainy conditions. However, avoid submerging it and ensure proper ventilation to maintain the battery management system BMS efficiency, especially in humid environments.
The 3% self-discharge rate means it can sit for a month with minimal loss, but for longer storage, keep it fully charged and store it in a cool, dry place. If it loses charge, use a compatible charger to recharge it. If issues persist, contact Vatrer support, as the 200A BMS may need a check for optimal performance.
No, this 12V 300Ah lithium battery is designed for energy storage, not engine starting. Its 200A continuous discharge are tailored for devices like refrigerators or air conditioners, not the high cranking power needed for car engines. Check the manual for alternative uses.
