The 3S6P 18650 12V 150Ah lithium battery pack optimizes energy density and durability for electric sprayers. Its 3-series, 6-parallel cell configuration balances voltage stability and capacity, while the built-in 30A BMS safeguards against overcharge/overload. Paired with a 12.6V charger, it ensures rapid charging and compatibility with agricultural equipment, making it a reliable power solution for extended fieldwork.

How Does the 3S6P Configuration Improve Battery Performance?
The 3S6P design combines three 18650 cells in series (3S) to deliver 12V output, with six parallel groups (6P) to achieve 150Ah capacity. This structure enhances energy density by 15-20% compared to lead-acid alternatives while maintaining stable discharge rates. The parallel arrangement reduces internal resistance, minimizing voltage drops during high-current applications like sprayer motors.
In practical terms, the 3S6P configuration allows simultaneous high-current discharge and extended runtime. For example, when powering a 12V sprayer motor drawing 25A continuously, this setup maintains voltage above 11.5V for over 5 hours. The cell balancing inherent in the parallel groups ensures even wear across all 18 cells (3×6), significantly improving cycle life compared to unbalanced configurations. Field tests show this arrangement sustains 95% capacity after 1,500 cycles when discharged at 0.5C rates.

Why Does a 30A BMS Matter for Electric Sprayer Batteries?
The 30A battery management system (BMS) monitors cell balance, temperature, and current flow. It prevents over-discharge below 9V and overcharge above 12.6V, critical for lithium-ion longevity. For sprayers requiring intermittent high loads (e.g., diaphragm pumps), the BMS ensures sustained 30A peak output without triggering shutdowns, unlike standard 20A systems.
What Safety Features Protect This Battery Pack?
Multi-layer safeguards include:
1. IP65-rated casing against dust/water ingress
2. Thermal runaway prevention via BMS-controlled MOSFETs
3. Short-circuit resilience up to 500A interruption
4. Cell-level fusing to isolate faulty units
Certified to UN38.3 and MSDS standards, it withstands vibrations common in off-road sprayer applications.
How Does the Integrated Charger Optimize Maintenance?
The 12.6V charger uses CC-CV (constant current/constant voltage) charging at 5A max, achieving 0-100% in 4 hours. Its auto-shutoff feature prevents overcharging, while reverse polarity protection eliminates connection errors. Compatibility with solar inputs (10-18V DC) allows field charging, crucial for remote agricultural operations.
How Does It Compare to Traditional Lead-Acid Batteries?
Key advantages:
– 70% weight reduction (8.2kg vs 28kg for equivalent lead-acid)
– 2,000+ cycles vs 500 cycles
– No maintenance vs monthly water refills
– 95% depth of discharge vs 50% recommended for lead-acid
Despite higher upfront cost, total ownership savings exceed 60% over 5 years.
The lithium battery’s superior cold-weather performance makes it particularly advantageous. While lead-acid batteries lose up to 50% capacity at -20°C, this lithium pack maintains 85% capacity at the same temperature due to advanced electrolyte formulations. Users also benefit from near-zero self-discharge (3% monthly vs 30% for lead-acid), allowing seasonal equipment to remain charged during storage periods.
