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) |
Discharge time≥4h |

Ryder Electronics established in Shenzhen on July 18, 2005, mainly in the business of battery packs. In 2009 the company passed ISO9001 and improved the product quality standard to fulfill the high-end requirements from our customers.
In 2012, Ryder Electronics moved to a new facility and expend the production capacity, the Productivity improved nearly 10 times than before.
In 2013, Ryder Electronics imported ERP (SAP) system to supervise order execution process.
In 2017, Ryder Electronics expanded the SMT, imported high-speed patch machine from Germany.
Until now the factory grows into a modern enterprise which integrated injection molding, PCB designing, SMT and battery pack assembling services.
In 2018 the company passed ISO14001certification, introduced automated battery production line to further improve the production quality and capacity.
