When comparing batteries you can just compare Stated (Name Plate)

Ah does not equal Ah capacity

 

 

DoD = Depth of Discharge

 

Trojan T105 Led Acid DoD is about 30%

About 3,000 cycles  approximately 3-5 Years

Consistently Using about 50% of the battery

 

Lithium Ferrous Phosphate   DoD is about 50%

Simpliphi Batteries

Predetermined voltages 12v, 24v, 48v

1 SimpliPhi 24v battery  =  4-Trojan T105

String as many as you want in Parallel.

About 10,000 cycles approximately 10 Years

Consistently Uses about 80% of the Battery

Built in Battery Management System  (BMS)

No overcharge No undercharge

OCDP - OverCurrent Protection Device (Circuit Breaker)

 

Plug and Play w/standard inverter chargers available today

 

Can Safely discharge 100% while maintaining 98% efficiency

Has own Breaker

No restrictions on where you can install

Can be installed on its side

No Maintenance

Battery can FREEZE without Damage

Over the life of the system

Lithium Ferrous is about 1/2 the cost of Led Acid

Safe - No Fumes or off gassing
