Lithium battery 12V 50Ah Electrical Characteristics & Test Condition

@Testing Conditions: Ambient Temperature: 25±5℃; Huminity:45%~75%.

NO	Items	Criterion		Condition
1	Internal Impedance	≤20mΩ		Test the internal resistance of 50% SOC battery pack with 1 kHz AC internal resistance test instrument.
2	Capacity	≥55Ah		Rest for 1 hour after fully charged, then discharge with 0.33C current until the battery reaches the discharge cutoff voltage. Repeat above process for three times, if the discharge time is not less than 180 minutes, you can stop and define the Discharging current*time value (Ah) as battery capacity.
3	Cycle life (DOD%100)	≥2000cycle		Discharge with the current of 0.5C until it can’t discharge, and then rest it for 1h. Charge the battery following CC(0.33C)/CV(14.6V) mode to full capacity, and then rest it for 1h. Repeat above process until full charged capacity is no more than 80% of normal value. Accumulated times is defined as cycle life.
4	Discharge Temperature Characteristics	-20℃	≥70%	At 25±5℃ discharge the battery with the current of 0.33C to the cut-off voltage. Store the battery at various temperatures for 2h and discharge the battery with 0.33C to the cut-off voltage. Record the ratio between discharging & charging capacity.
		0℃	≥80%
		25℃	100%
		55℃	≥95%
5	Charge Retention ability	remain capacity≥90%		Charge the battery to full capacity and store it for 28days, and then discharge it with 0.33C to the cut-off voltage.

You can now replace the lead acid (SLA , AGM or GEL) batteries with these modern LiFePO4 batteries and see the difference in the performance immediately!

The size is the same, the performance and service-life is much better!

12V 55Ah Scooter Wheelchair Mobility Deep Cycle LiFePO4 Li-ion Battery 12V55Ah LiFePO4 Battery
Compared with Seal lead acid battery, lifepo4 battery has many advantages:

1. Green: Non-Toxic, comfort to RoHS.

2. Long cycle life: > 2000 cycles, while Sealed Lead Acid batteries only 750 cycles and NiMh batteries only 500 cycles)

3. Safety
The safest battery in the world till now, which does not burn with 30V charge voltage and it does not explore when you puncture the battery. UL approved.

4. Light weight and smaller dimension
The dimension is smallest and the weight is lightest when compare with other battery. 1/3 weight of SLA, 65% weight of NIMH.

5. Great capacity and more powerful, rechargeable battery
High discharge current, 1C continuous, 3C pulse for normal cells and 20 C for special design
We can install many single cells in series and in parallel and it can fully discharge

6. Good thermal stability: - 40°C to 70°C

7. Back fast charge, good consistence, no memory effect, can equip battery charger.
Can be recharged anytime, no reduction of the capacity

8. Widely application, customize solutions, mass production, OEM/ODM/buyer label provided.

Typical Application:

Communication base station
Power monitoring,Portable applications
billboard,Patrol car
Automotive application
Electric forklift
Solar street lamps
UPS power supply
Household energy storage
Hydrological monitoring
