Features

12V miniature regenerative lithium iron phosphate battery, lightweight and portable, endless energy storage.

The bright LCD display can be added as an extra, as bright as a mirror lake, reflecting the vagaries of battery voltage and capacity in real time. She is crafted from high quality lithium iron phosphate, as solid as a rock, safe and reliable.

She has a long life course, a distant 10 to 15 years ahead, like the tailor of time, sewing long sleeves for life. She has stepped up to replace heavy-duty lead-acid (AGM / GEL) batteries, and despite weighing only one-third as much as the original, her capacity has not diminished a bit.

Her cycle life is as instantaneous as a star, 2000 cycles @ 100% DOD, 6000 cycles @ 50% DOD, and the light of day melts into infinite years in her memory, demonstrating amazing durability. Just like the flow of notes, the extension of charging time and the improvement of service life, she is economical, environmentally friendly, and she is the companion dancer of time.

She is equipped with many talents and is able to cope with both series and parallel connections. Like a flexible dancer, she has a built-in BMS and carries multiple safety protections, so that no matter how the wind rises, she can remain stable.

 

FAQ:

Why should I buy an ion lithium deep cycle battery?
1. Ion lithium deep cycle batteries offer several advantages over standard lead acid batteries used for energy storage purposes, which we will outline below:
2. Significantly lighter - Lithium-ion batteries are a fraction of the weight of the original lead-acid batteries.
3. more powerful - Lithium-ion batteries operate at a higher voltage than standard lead-acid batteries, allowing your engine to rev faster and last longer. Lead-acid batteries deliver only 12.5V when only 20% of the battery capacity is used, while lithium-ion batteries deliver more than 12.8V even when only 20% of the battery capacity is used.
4. Low self-discharge rate - Lead-acid batteries lose 4%-25% of their capacity each month, depending on the quality of the plates and separators used. If a vehicle is left unattended for a month, the lead acid battery may lose too much charge and the vehicle may not start. On the other hand, our lithium-ion battery chemistry loses less than 3% of its charge per month; you can go months without worrying.
5. Environmentally Friendly - Ion batteries do not contain toxic substances. They do not contain toxic lead or corrosive sulfuric acid, so there is no possibility of explosive gassing events, which are common with lead-acid batteries. In addition, there is no need to maintain acidity or worry about venting as with traditional lead acid batteries. The only maintenance required for ion batteries is to ensure that the battery is never depleted beyond 80% to ensure optimal life.
6. Long-Lasting - Inexpensive lead-acid batteries typically only last 1 to 2 years, while gel and AGM lead-acid batteries can last 3 to 5 years with proper maintenance. However, lithium-ion batteries can provide 8 to 10 years of use, easily outlasting any lead-acid battery. Battery life is entirely dependent on proper operation and maintenance, so follow common sense and make sure your batteries are not discharged more than 80%. If you're replacing lead-acid batteries in two years or less due to deep cycle damage, switching to lithium-ion batteries will save you money in the long run!
7. Fast-charging lithium-ion batteries accept charging current up to five times faster than lead-acid batteries. What's more, lead-acid batteries charge at about 75% efficiency, while Ionic's lithium-ion batteries charge at 97% efficiency. This means less energy is required to charge and less strain is placed on the alternator.

What is a LiFePO4 (Lithium Iron Phosphate) battery?
Lithium Iron Phosphate (LiFePO4) batteries are lithium batteries that offer several advantages over traditional lithium-ion batteries based on the LiCoO2 chemistry.LiFePO4 batteries offer higher specific capacity, superior thermal and chemical stability, enhanced safety, improved cost performance, enhanced charging and discharging rates, and enhanced cycle life, and are available in a compact, lightweight package. LiFePO4 batteries have a cycle life in excess of 2,000 charge cycles!

Is LiFePO4 more dangerous than lead acid/AGM?
No, it is safer than lead acid/AGM. In addition, the GreenLiFE Lithium Battery™ has built-in protection circuitry. This protects against short circuits and has under/over voltage protection. Lead/AGM is not, and flooded lead acid contains sulfuric acid that can spill and harm you, the environment, and your equipment. Li-Ion batteries are sealed, have no liquid, and do not release gas.

What can I use lithium-ion batteries for?
You can use lithium-ion batteries in any application that would normally use single or multiple lead-acid, gel, or AGM batteries. greenLiFE® batteries are commonly used in marine, RV, solar, industrial, performance, golf cart, UV, mobile, UPS, and custom applications!
