Advantages of LiFePO4 Battery?

Why LiFePO4 Lithium Batteries Are The Best

Here are some Benefits to using LiFePO4: 

Higher capacity for the same physical size of lead acid.

Can be discharged to 90% vs lead acid or AGM recommended 50% depth of discharge.

Can be discharged at high current rate without losing Ah capacity vs lead acid which can be reduced to 40% Ah rating at high discharge rate.

Can be installed indoors with no hydrogen gasses generated.

About 1/3 the weight of lead acid.

Doesn’t need temperature compensation for charging.

Installing indoors can reduce cable length which reduces voltage drop and power loss.

Installing indoors reduces risk of theft.

Installing indoors reduces tongue weight from the front of a trailer.

Output voltage is flat during most of the discharge cycle. About 13V.

Output voltage is higher than lead acid which keeps electronics operating longer.

Higher output voltage reduces inverter current draw by approximately 10%.

Can be charged faster. Up to .5C vs .2C with lead acid.

Absorption mode is at the very end of charge instead of at a typical 80% for lead acid. This drastically reduces charge time.

Can last many years (3000 cycles) vs approximately 2-5 years (300 cycles) for lead acid.

Holds a charge for up to 1 year (without a load) without the need for a trickle charger.

Higher voltage and higher current capability allows generator to start easier without low voltage lag.

Lithium Iron Phosphate Battery Pack Can be recharged at least 3000 times and retain 80% of original capacity.

Lifetime cost per Ah is about 10% of the cost of lead acid.
