PayPalSpring is here and its time to start digging out RV trailers and getting ready for summer camping. If you have old tired batteries dont miss this deal!
I bought this battery last fall after my normal lead acid batteries died on a camping trip last fall. I bought this one to replace those. It was used 1 trip and still like brand new.
I put a 2000watt inverter on it running some work lights in the garage to test the capacity, at a -13amp draw for 20 hours continuously the battery only dropped to 37%!! This has an incredible amount of juice. It should be equal to about 4 lead acid batteries. The bonus of LIFEP04 is you get twice the discharge depth over lead acid, and will last thousands of charge / discharge cycles (MFG states 15,000 cycles!). Normal lead acid batteries typically last 200-800 cycles. There's a great chance this will be the last battery you ever buy for an RV. Also useful for home power systems, other places you need a lot of juice.
The bluetooth works very well and simple on a phone with their free app. Its very convienent to see the total state of charge in the battery in percentage form, also you can see temperature, amperage current etc etc. This battery can be charged or discharged at 100 amps, about 5 times more amperage than you can get out of a home 110v plug.
I paid $400 for this with tax and shipping this past Sept. With the current war, prices of batteries have skyrocketed in the past month. I'm only selling this as I'm going to go with even bigger batteries for my RV trailer.
Here are the mfg specs on this battery:
Hassle-Free High Capacity: This HumsiENK 12V 314Ah Mini LiFePO4 Lithium battery offers an impressive 4.01 kWh of energy, surpassing three 12V100Ah/ 12V 300Ah lithium batteries connected in parallel. Perfect for RVs, solar systems, home storage, trolling motors, and marine use. Supports up to 4S4P configurations for a maximum capacity of 64.307 kWh.
Bluetooth 5.0 Smart Monitoring – Real-time tracking via HumsiENK App (iOS/Android) for voltage, current, capacity, and temperature. 15m Bluetooth range for easy remote monitoring.(download via App Store or request QR for Android)HumsiENK provides 5-year coverage and 24-hour customer service for a worry-free experience.
Grade A+ Cells & 100A BMSHigh-level battery management system (BMS) provides overcharge, over-discharge, over-current, and short-circuit protection to ensure long-term safety and stability. High temperature cut-off prevents charging above 145°F (65°C), making it safer than lead-acid alternatives. It can adapt to a wider range of temperature environments, giving it an advantage as an outdoor RV battery.
Space Saving & High Energy DensityThe mini compact size of HumsiENK 12V 314Ah Bluetooth battery is 15.1×9.7×7.6 inches. Due to its high energy density, this battery has twice the usable capacity of lead-acid batteries and is 40% lighter in weight, making it easy to carry. Weighing only 59.5 pounds, it maintains high performance while taking up less space to fit seamlessly into various RV layouts.
Low Temperature Cut off ProtectionThe integrated BMS automatically cuts off charging under low temperature conditions, preventing irreversible battery damage and ensuring service life in extreme conditions. HumsiENK provides five-year solutions for all batteries. 24-hour friendly and professional customer support, if you have any questions, please feel free to contact us for help.
Wide ApplicationIdeal for home energy storage, UPS backup power, RV, camper, golf cart, trolling motor, yacht, solar system, digital/CCTV camera, DIY project, etc. Versatile solution for both leisure and professional use.
