Litime 2-Pack 12V 230Ah Bluetooth Lithium RV Battery, Low Temp Cutoff Protection, Built-in 200A BMS, Max 2944Wh Energy, LiFePO4 Battery Perfect for RV, Trolling Motor, Off Grid, Backup Power

Awesome RV Trailer Battery. This new Lithium Batteries replaced my 2 OEM Lead Acid batteries and will give me 130 more Ah! What can a towable trailer ask for. I love the new Smart Bluetooth connection/application too. The packaging was superb, great instruction booklet and initial charging was completed in 4 hours. Easily installed, checked the smart application (Bluetooth) and ready to roll.

This is the largest AH lithium battery that would fit in my 2015 Sunseeker motorhome that is a GTS model so it has a smaller battery compartment than most other full size Sunseekers. At only 7.25" wide, this battery barely fit. I added a 2000w inverter and can run the microwave on this while as consumes 190A at 12V when at 2000w output. This battery is a smart version and I can monitor it from a phone app instead of a shunt and separate meter. I might want to caution users of LiTime "Smart" batteries to only use one large battery as multiple smart batteries have an issue that if fully charged, parallel ones may not provide current. I hope LiTime updates their BMS firmware for this but for now I only needed 230Ah.

Much lighter and way more energy than the two lead acid batteries I replaced. It has a slightly smaIler footprint than two lead acid batteries, so it fit into the box nicely. I like the blue tooth connectivity that allows me to monitor battery energy level and output. I was able to turn on and off various items in my travel trailer and get a measurement of the amp draw. That enables me to better predict how long I can go between charges. Not sure if it the BMS or my converter, but the converter normally only charges the battery at about 5 or 6 amps (I have seen as high as 10 amps but not for an extended period of time).

I needed a battery that would power my trolling motor all day without leaving me without a trolling moor halfway through the day of fishing! My primary problem with batteries is that there is simply no way to tell how long the battery will last at any given draw rate. With this battery, the Bluetooth functionality not only tells me what the draw is, but also how long the battery will last at that given draw rate! This 12VDC, 230 Ah battery runs my trolling motor for two full days of fishing, and always keeps me informed to the state of the battery! This battery also needs to do double duty during Hurricanes, when we go to 12VDC for our electricity to power lights, computers, telephones, and television in the house! This battery does it all while providing me with how long I have till I need to recharge the battery with the generator! Connecting two batteries in parallel? The Bluetooth functionality will balance the two batteries so they work together as a unit! As for weight, this battery is twice the size of my old lead-acid battery, yet provides three times the power of the old battery while weighing the same as the old battery!

We've got half a season of summer camping since I installed this LiFePo. This thing is great and was one of the best things we've done for our boondocking style of camping. Well, this and the solar which was done years ago. Love the BT access for checking the battery status. The only thing bad is that I love it so much I am always checking the app on my phone so that I can smile more. Eventually maybe I will learn to just let it do its job and not look so much. Our 400 watt hours of solar keep this battery in tip top charge, even if partially cloudy.
