Litime12V 230Ah Plus Low-Temp Protection LiFePO4 Battery Built-in 200A BMS, Max 2944Wh Energy, Lithium Iron Phosphate Battery Perfect for Trolling Motors, Yacht, Marine, Boat, RV, Home Energy

I wanted to publish the following information I received from Li Time Customer Service after I sent them an email that I was having some strange behavior when initially charging the battery using a 14.6V 20A Li Time Charger that I also purchased. This might help others avoid confusion and frustration. I can say that their support was excellent and within the 24 hour response time they promise.I will share the description of the issue I sent to Li Time and the response I received. It turns out that everything was operating as designed. I did respond back to them and ask that they publish the explanation in their product manuals and/or Website so customers don't waste time TS or think they have a faulty product.Issue:I just bought a 12V 230Ah from Amazon and delivered 3/15/24. I also bought at Li Time 14.6V 20A charger from Amazon. I was finally able to charge and use this weekend.I measured the standing voltage at 13.17V "As Shipped" to me. I connected the charger and let it run all day. When I first connected the charger, I measured the voltage across the terminals at 13.46V. A few hours later it measured 13.6. Again a few hours later it measured 14.1V. Hours later I checked the charger and the Li Time LED light was flashing Red and then Green. At that point I measured the standing voltage at was 12.94V.I'm not sure the 12.94 voltage make sense if the battery is fully charged. I expected the standing voltage to be much higher when fully charged. I assumed a fully charged battery would have a standing voltage of 13.6V.I connected the battery today to my RV and tested by turning on my propane refrigerator. I also connected a Multifunction Meter with a shunt to monitor voltage and current. When I first connected the meter and shunt with no load, the voltage measured 12.84V. When I turned on the RV refrigerator, the voltage measured 12.62V. A few minutes later I looked at the meter again and the voltage measured 13.24V. 2.5 hours later the voltage measured 13.21. This seemed very odd to me that the voltage jumped from 12.62 to 13.24 in a few minutes. There is no AC power and/or charger connected to the RV. minutes.Can you help me to understand if this is normal or is there an issue with the battery and/or my charging process. I really need some advice on this and what next steps to take.Thank you in advanceResponse:Thank you contacting LiTime service, it's Ricket, i will be of your any assistance.Don't worried, it was the over-charged protection by the BMS.The original intention of our design is that after the battery is fully charged to about 14.4V, theoretically the battery voltage will slowly fall back to the resting voltage of about 13.33V after charging is turned off. However, the logic of most protection boards and chargers currently on the market is When the voltage drops back to about 13.8-14V, charging will be restarted unless the charger is disconnected. If the user does not disconnect the charger in time, it means that the battery will be cut off by repeated charging and cause voltage oscillation. Therefore, when we develop the protection board, we will protect the battery. The recovery voltage of the board after overcharging is designed to the battery's resting voltage of 13.33V, so that the battery will not be repeatedly charged and cut off, which is a benefit for protecting the board. After the battery is charged, the measured voltage is about 12.9V, which is exactly The virtual voltage after full charge protection. At this time, the charging channel is closed, but it does not affect the use. As long as the protection board is normally loaded, it will be reactivated and started.When you checked the resting voltage within 12.8-13.1V after fully charged, just need to connect with the small rated load to discharge 2-3 minutes with greater 2A discharge current and then you will see the resting voltage ≥13.33V.Thanks for your understanding and wish you a good day.

Had these batteries for about 9 months now in my RV and they have performed flawless. I have discharge them down to about 7% according to my battery monitor and they recharged back to 100 with no issues. I kinda wished I had waited a few months cause they now have a model with Bluetooth. The purchase price was good and the battery is performing like it should. The seller kept in touch during shipping to let me know when they left and packaging was well adequate enough for shipping. Will buy again

Excellent capacity for the size and weight. I installed two of these batteries in my RV. I charge them with 800 watts of solar. Out preforms any other battery I have ever had in an RV.

The battery was delivered on January 27, fully charged and installed it on my travel trailer on the 29th. Today is February 18, and I haven’t put any charge on it since installation. Granted, I haven’t been camping in it, but I’ve been spending a few hours each day in it working on maintenance and repairs. All lights and radio on during those times. The battery monitor read 0% today, but I was still using 175 watts for several hours on that 0%. I’m guessing the battery monitor simply needs to be calibrated.All I know is I could easily dry camp in my RV with this battery for at least 2 weeks without having to recharge! We typically only dry camp for 4-6 days at a time, so I’m probably not even going to bother investing in any solar panels just yet.This battery replaced a pair of golf cart batteries and probably weights about half as much as just one of those.The heavy duty foam that it came packed in is perfect for stuffing into an oversized battery box to keep the battery from sliding around.

Battery arrived dead and will not take a charge. When you put a lifepo4 charger on battery it shows charged but volt meter reads less than 1 volt You cannot return it and i am trying to get a refund now, big hassle. Will update later UPDATE customer service was 24 hour turnaround did try to help but could not get battery to take a charge they offered a refund and I took it. they offered shipping label, no hassle.Did buy same battery but with blue tooth received it. It seems to work perfectly.

Good battery

These batteries are AWESOME! Would definitely buy again.

Great! Light weight and powerful
