Part1: 4S2P Lithium Battery Pack Basics
1.1 Series-Parallel Configuration Explained
You need a lithium battery pack that delivers both high voltage and capacity for demanding medical devices. The 4s2p lithium battery uses a series-parallel structure, which means you connect four cells in series and two in parallel. This arrangement creates a pack with eight cells in total. The series connection increases the voltage, while the parallel connection boosts the capacity and reliability.
Configuration | Description |
|---|---|
Series Cells | 4 cells in series |
Parallel Cells | 2 cells in parallel |
Total Cells | 8 cells (4S2P) |
Full Charge Voltage | 16.8 volts |
Nominal Voltage | 14.8 volts |
Discharged Rating | 12 volts |
This structure allows you to achieve higher energy density and extended runtime, which are essential for portable oxygen concentrators and medical infusion pumps. The 4s2p lithium battery doubles the capacity compared to a 4S1P pack, supporting longer runtime and reducing the frequency of battery changes.
1.2 Voltage and Reliability for Concentrators
You benefit from a stable nominal voltage of 14.8V, which matches the requirements of most concentrator designs. This voltage ensures continuous operation and prevents sudden power loss. The parallel cell arrangement adds redundancy, so if one cell fails, the pack continues to function. A battery management system monitors each cell, preventing overcharge, over-discharge, and overheating—critical features for patient safety.
The 4s2p lithium battery provides:
Higher reliability for continuous operation.
Uninterrupted performance during power outages.
Enhanced safety through built-in monitoring and redundancy.
You can trust this configuration to deliver consistent power, minimize downtime, and support the demanding needs of medical environments.
Part2: Performance and Compliance
2.1 Longer Runtime and Oxygen Concentrator Performance
You need a lithium battery pack that delivers longer runtime and reliable operation for portable oxygen concentrators. The 4s2p lithium battery configuration provides extended runtime, supporting continuous oxygen delivery for critical medical applications. You can expect runtimes ranging from 2 to 10 hours, depending on the number of battery packs used and the concentrator’s power consumption.
Battery Configuration | Runtime (hours) |
|---|---|
Single Battery | 2.4 |
Double Battery | 4.8 |
Triple Battery | 7.2 |
This longer runtime ensures uninterrupted therapy, reducing the need for frequent battery changes and minimizing downtime. You benefit from higher energy density and high gravimetric energy density, which allow for compact designs without sacrificing performance. The 4s2p lithium battery supports higher reliability, making it ideal for medical infusion pumps and oxygen concentrators that require stable power for extended periods.
You can rely on custom lithium battery packs to deliver consistent oxygen concentrator performance, even in demanding environments. These packs maintain reliable operation during emergencies and travel, supporting patient safety and comfort.
2.2 Discharge Rate and Power Output
You require a lithium battery pack that meets the high discharge rates demanded by portable oxygen concentrators. The 4s2p lithium battery provides a max continuous discharge current of 5.2A, ensuring sufficient power output for medical infusion pumps and oxygen concentrators during peak demand.
Parameter | Value |
|---|---|
Max Continuous Discharge Current | 5.2A |
Nominal Voltage | 3.7V |
Nominal Capacity | 5200mAh |
Stable power output is essential for oxygen concentrator performance in medical and industrial settings. Lithium iron phosphate (LiFePO4) batteries offer high capacity, long cycle life, and reliable operation, making them suitable for continuous use. High-capacity battery packs help maintain stable operation, even when environmental conditions change. Safety certifications, such as IEC 62133 and UL 1642, ensure reliable oxygen delivery during critical procedures.
Key Point | Explanation |
