Product Description

RYDBATT Li-18650-4S3P-14.8V 6.6Ah-PCM Li-ion Battery Pack 14.8V For Industrial Li-ion battery

 

Advantages
Very low profile - batteries resembling the profile of a credit card are feasible.
Flexible form factor - manufacturers are not bound by standard cell formats. With high volume, any reasonable size can be produced economically.
Lightweight - gelled electrolytes enable simplified packaging by eliminating the metal shell.
Improved safety - more resistant to overcharge; less chance for electrolyte leakage.
Limitations
Lower energy density and decreased cycle count compared to lithium-ion.
Expensive to manufacture.
No standard sizes. Most cells are produced for high volume consumer markets.
Higher cost-to-energy ratio than lithium-ion

Test Conditions

Requirements

1

Capacity retention

Fully charging, store them at (20±5)℃ for 28 days, then discharge to

11V @0.2C.(the residual capacity is above 85% of nominal capacity)

Discharging time4.25h

2

Cycle Life @25℃

Discharge to 11V @0.2C, then Charge the battery @0.2C to reach 16.8V. Then charge the battery at constant 16.8V voltage until the charging current decreasing to 0.02C. Rest for 10 min. discharge to 11V@ 0.2C and rest for 10 min. Continue the charge/discharge

cycles until discharge capacity lower than 80% of rated capacity.

Cycles life ≥300

3

storage

Charge the battery to 40%~65% of its rated capacity using standard charging mode, then keep it in an 20℃±5℃, humidity 45% ~ 85% room for 12 months, fully charge and discharge it @0.2C until voltage down to 11V.

(The testing sample should be within 3 months dated from production date)
