Part1: 3S2P vs 4S1P Lithium Battery Packs
1.1 3S2P Configuration Explained
You encounter the 3S2P configuration frequently when evaluating Lithium Battery Packs for portable patient monitors. In this setup, three cells connect in series (3S), and two strings of these series-connected cells run in parallel (2P). This arrangement increases both voltage and capacity, making it suitable for devices that demand extended uptime and stable power delivery.
Parameter | Specification |
|---|---|
Product Name | 10.8V 6.7Ah Li-ion Battery |
Configuration | 3S2P |
Cell Type | 18650 3.6V 3350mAh |
2A | |
Dimension | PVC 385870 mm |
Common Applications | Backup Power Systems for medical equipment |
You benefit from the higher capacity and moderate voltage range, which supports longer operation between charges. Typical voltage ratings for 3S2P Lithium Battery Packs （using 18650 or 21700 cells） range from 10.8V to 11.1V, with capacities between 6Ah and 10Ah. The following table summarizes common ratings:
Voltage | Capacity |
|---|---|
10.8V | 6.7Ah |
11.1V | 10Ah |
You also gain from the robust energy content, which can reach up to 66.6Wh. The cycle life often exceeds 500 cycles at 25ºC, ensuring reliability in clinical settings. The integrated BMS enhances safety by monitoring cell health and preventing overcharge or deep discharge.
Tip: Choose 3S2P Lithium Battery Packs for patient monitors that require high capacity and consistent voltage output, especially in environments where uninterrupted operation is critical.
1.2 4S1P Configuration Explained
You may consider the 4S1P configuration for applications that prioritize higher voltage over capacity. In this setup, four cells connect in series (4S), and there is only one parallel string (1P). This design delivers increased voltage, which can be essential for devices with higher power requirements but limited space for additional cells.
Parameter | Specification |
|---|---|
Configuration | 4S1P |
Cell Type | 18650 3.6V 3350mAh |
Nominal Voltage | 14.4V |
Nominal Capacity | 3.35Ah |
Energy Content | 48.24Wh |
Typical Weight | 210g |
Common Applications | Medical, robotics, security, industrial devices |
You achieve a higher voltage output, typically around 14.4V, which supports devices that need more power in a compact form factor. However, the capacity is lower compared to 3S2P, which may reduce operating time between charges. The 4S1P configuration is ideal for patient monitors with short bursts of high power demand or where size constraints limit battery volume.
Note: Select 4S1P Lithium Battery Packs for devices that require higher voltage and can operate efficiently with lower capacity.
1.3 Technical Differences
You must understand the technical differences between 3S2P and 4S1P Lithium Battery Packs to make informed decisions for your medical devices. The following table compares key specifications:
Feature | 3S2P Configuration | 4S1P Configuration |
|---|---|---|
Voltage | 10.8V | 14.4V |
Capacity | 6Ah – 10Ah | 3Ah-3.5Ah |
Energy Density | Moderate to High | Moderate to High |
Cycle Life | 500+ cycles | 500+ cycles |
Weight | ~310g | ~210g |
Typical Application | Extended uptime, backup | High power, compact size |
You should also consider battery chemistry when selecting Lithium Battery Packs. The most common chemistries include:
Chemistry | Platform Voltage | Energy Density (Wh/kg) | Cycle Life (cycles) |
|---|---|---|---|
LCO | 3.6V | 150–200 | 500–1000 |
NMC | 3.7V | 200–250 | 1000–2000 |
3.2V | 90–120 | 2000–5000 | |
LMO | 3.7V | 100–150 | 300–700 |
LTO | 2.4V | 70–80 | 7000–20000 |
You find that NMC and LiFePO4 chemistries are popular in medical devices due to their balance of energy density, safety, and cycle life. Lithium-ion batteries offer high energy density and long cycle life, making them suitable for portable patient monitors.
Alert: Always verify the compatibility of Lithium Battery Packs with your device’s voltage and current requirements. Ensure the BMS supports the intended application to maximize safety and reliability.
You optimize device performance and safety by selecting the right configuration and chemistry for your portable patient monitors.
