There are many differences between lead batteries whether they be flooded, AGM or GEL, and li-ion batteries.

Weight Savings

LiFeBlue batteries are less than ½ the weight similar sized of lead acid batteries.  A 105AH Lead Acid battery is about 65 pounds. LiFeBlue 100AH battery is 29 pounds and that’s including energy management and a battery monitor.  

High Energy Density

Lithium batteries have a high energy density which means you can pack more battery capacity in a given space than if you used lead batteries. In an RV or boat, this can be a signicant savings.

Charge efficiency

LiFeBlue batteries are nearly 100% efficient. That means it only takes a small amount more energy to recharge than what you removed from the battery. Lead batteries take 10% to 30% more energy to recharge.

Charge speed

LiFeBlue batteries recharge far faster than any lead acid battery.

Let’s compare 2 100AH Fullriver batteries and 2 100AH LiFeBlue batteries with 150AH removed.

LiFeBlue charge rate = up to 160A; Time to full charge: 1 hour

Fullriver charge rate = Max. 50A; charge time >7 hours

The reason lead charges so much slower is you must limit the current during the bulk charge cycle and the final 20% of charging is based on time, not current, and that takes 3-5 hours for any lead acid battery. This difference is huge if using fuel to run a generator. It also means that a much smaller PV solar charging system can be used. With limited roof space, this is a great advantage.

Depth of Discharge and Cycle Life

Despite the fallacy perpetuated on countless battery websites and blogs, all deep cycle lead acid batteries can be discharged 100% if necessary. The result of doing so will greatly reduce the number of cycles you get. The same principal affects all lithium ion batteries. The difference being that with LiFeBlue Battery, you will get over 2800 cycles if discharged 100% and with most lead batteries you will get less than 500 cycles. (based on 80% remaining capacity) This means that under any DoD, LiFeBlue battery will outlast lead acid by 5 to 1 or better. By reducing the discharge depth to 50%, LiFeBlue battery can produce more than 6000 cycles. This compares to about 1200 cycles from lead acid.

High Voltage

Lithium-ion batteries maintain a very consistent and high voltage throughout the discharge cycle. This results in lower current and longer life for electronics. It also means lights are brighter and slide outs move faster. When lead acid voltage drops, the current and heat increase and this shortens life of electrical components.


Although LiFeBlue Battery costs more up front, the cost of ownership is much less than with any lead acid battery when you consider the maintenance costs of lead and long life of LiFeBlue.
