Why spend the money on a lithium battery?

Performance Example:

Let’s say you are powering a refrigerator that requires 10 amps and you use a DoD of 30% with a 100Ah rated AGM/GEL

30 AH available capacity / 10 amp draw = 3 hours of usage

Let’s say you are powering a refrigerator that requires 10 amps and you use a DoD of 50% with a 100Ah rated AGM/GEL

50 AH available capacity / 10 amp draw = 5 hours of usage

Using a lithium battery with no DoD recommendation

100 AH available capacity / 10 amp draw = 10 hours of usage

There are several differences between lithium batteries and AGM. See below for a brief explanation:

Benefits of lithium batteries:

Lithium batteries offer up to 8x more charge/discharge cycles than AGM & GEL batteries
Lithium batteries are 1/2 the weight of AGM & GEL batteries
You will need 3 AGM / GEL batteries to every 1 lithium battery if you follow the DoD % recommendation for AGM & GEL technologies
Utilize the full rated amp capacity without harm to the battery
Constant output voltage

Extremely high number of charge/discharge cycles
> 10 Year lifespan with proper maintenance
No need to worry about depth of discharge
Wide operating temperature range
Unsurpassed high temperature performance
Green energy without metal contaminant
Low maintenance
High amp capacity
Stable output voltage
Little self-discharge
BMS safety protection
Convenient removable carry handle
Lightweight
Sophisticated Battery Management System (BMS)

100 Ah Battery Comparison	AGM	GEL	Lithium
Average Price	$210	$220	$849
# of cycles @ 30% depth of discharge (DoD)	1200	1200	4000
# of cycles @ 50% depth of discharge (DoD)	500	500	4000
Lifespan (depends on battery maintenance)	2-3 years	2-3 years	9-10 years
Size	13x9x7″	13x7x9″	13x7x9″
Weight	74 lb	71 lb	31 lb

**Depth of Discharge (DoD) is used to describe the % of the battery’s energy that has been discharged. For example, if the battery is charged 100%, its DoD is 0%. If the battery is 100% discharged, the DoD is 100%. If the battery’s DoD is 40%, it still has 60% of its energy. It is another way of stating the battery’s state of charge. GEL/AGM battery manufactures recommend a % of DoD to prolong overall battery life.
