LiTime lithium batteries are certified by UL, FCC, CE, RoHS & UN38.3
Precautions to Take
1. Please don't use the battery for golf carts.
2. As deep cycle battery, don't use it to start the engine.
3. When connecting the batteries in series or parallel, make sure they are of the same brand, type, voltage, amps, BMS and within 1 month.
4. Charge temperature: 32℉ to 122℉
Discharge Temperature: -4℉ to 140℉
Storage Temperature: 14℉ to 122℉
Trusted Power for Every Journey
A LiTime LiFePO4 lithium battery offers 4,000 to 15,000 life cycles, translating to 10 years or more depending on usage. In contrast, lead-acid and AGM batteries typically provide only 300 to 500 life cycles before significant capacity loss. While LiTime LiFePO4 batteries have a higher upfront cost, they deliver substantial long-term savings.
The output current of a 50Ah lithium battery is inversely related to usage time. For instance, if it delivers 50 amps, the theoretical runtime is one hour. At 25 amps, it lasts for two hours; at 10 amps, it runs for five hours; and at 5 amps, it continues for ten hours, and so on.
LiTime advises using the 12V 10A LiFePO4 lithium battery charger for the 50Ah battery, which will fully charge it in approximately 5 hours (50Ah ÷ 10A = 5h).
No. LiTime 12V 50Ah lithium batteries are not intended to be used as starting batteries but energy storage, please do not use them to start any devices.

Yes, you can charge LiTime LiFePO4 lithium batteries with solar panels. Here are 3 reliable ways to charge
1. Using Solar Panels + Solar Charge Controller
The LiTime 12V 50Ah battery can be fully charged by in one day (with effective sunshine 4.5hrs/day) by 200W solar panels. It may take more than one day to fully charge the battery by ≥200W solar panels since the duration and intensity of light would be a great factor for their charging efficiency.
2. Generator/Alternator
If the alternator or generator supports DC output, a DC-to-DC charger is needed to connect the battery to the generator; if your alternator or generator supports AC output, please add a suitable battery charger to connect the battery and the generator according to our recommendations.
The Recommended Charging Voltage: 14.2V - 14.6V. The Recommended Charging Current: ① 10A (0.2C): the battery will be fully charged in around 5 hrs to 100% capacity; ② 25A (0.5C): the battery will be fully charged in around 2 hrs to around 97% capacity.
To charge 12V battery, it is recommended to use 14.6V battery charger.
The Recommended Charging Voltage: 14.2V - 14.6V.
The Recommended Charging Current: ① 10A (0.2C): the battery will be fully charged in around 5 hrs to 100% capacity; ② 25A (0.5C): the battery will be fully charged in around 2 hrs to around 97% capacity.

LiFePO4 batteries can safely charge between 0℃ to 50℃ / 32℉ to 122℉. LiTime cold weather batteries include the low-temperature charging protection which will automatically cut the battery charging off when the cell temperature is lower than 32℉, thus preventing the battery cells from damage when charging under the freezing point.

For optimal longevity, store your LiFePO4 batteries under the following conditions:
For storage exceeding three months, adhering to these guidelines will significantly preserve your battery's health and performance:
This battery lasts far beyond what is advertised. Charges everything i need for 9 straight hours a day. Super light weight. Ill be getting nothing but LiTime batteries from now on, with a 100ah next.
Instead of running 800 feet of electrical wire, I built a box to hold the battery, charge controller, and wiring for the gate, gate pillar lights, and a flagpole light. Uses about 15 Ah per night. This battery was easy to integrate into my solar system (100W panel) and has done an excellent job over the past week. The key is to see if it lasts more than the 2 years my prior setup did.
The LiTime 12v 50ah lithium battery was a excellent purchase to run the new Garmin live scope lvs34 electronics I installed on my Ranger boat, on one full charge I can fish 2 full days with out a recharging, I highly recommend this product and very pleased with my purchase, and customer service was excellent.
No issues works great
I have only used my Garmin Livescope twice powered with my new LiTime battery. It has worked flawlessly and there is no distortion in my display. I recommend it.
I’m using the battery for my trolling motor on my inflatable pontoon. After the initial charge, I have had it out on four different trips, some to the lake & some to streams. The battery still has 65% left on it. It’s incredible not having to charge after every fishing trip. So far, this battery is absolutely worth the money. Well done LiTime!
I never got my delivery and I am not happy! Good luck to anyone who buys from you.
