Coslight Rechargeable 48V 100Ah LiFePO4  Battery Telecom Base Station Backup Battery:

1. Discharge and efficiency

Lithum-ion batteries are nearly 100% efficient in both charge and discharge allowing for the same amp hours in and out. Lithium batteries are discharged 100% while the best lead acids batteries can only be discharged 80%. Most lead acid batteries do not recommand more than 50% depth of discharge.

2. Voltage 

Lithium-ion batteries maintain their voltage throughout the entire discharge cycle. This allows for greater and longer-lasting efficiency of electrical components.

3. Long Cycle life

Rechargeable lithium-ion batteries cycle 4000 times or more @ 80% DOD.

4. Safe

5. Less self-discharge

 Self-discharge<2%(month), while the monthly self discharge of sealed lead acid battery is 10%.

6. Lighter weight and smaller volum

LiFePO4 battery technology is one of lithium-ion battery technolog, thus it has advantage-lighter weight of lithium battery. lithium-ion batteries are 1/3 the weight of lead acid batteries and 1/4 the volume of  lead acid batteries.
