Expert Tip: The 18V 2000mAh lithium-ion battery for Dongke JAVN tools uses high-density EVE cells for 30% longer runtime compared to standard NiCd packs. Its brushless motor compatibility reduces friction, enabling 20% more torque for heavy-duty fastening tasks.
The 18V 2000mAh lithium-ion battery delivers optimized power density for Dongke JAVN brushless tools, featuring EVE Battery’s stable discharge curve for consistent performance. Its modular design enables tool compatibility with 15+ starter models while maintaining compact dimensions (125x75x90mm) for tight workspaces. Built-in PCM protection prevents overloading during high-torque automotive applications.
How Does the Battery Chemistry Impact Performance?
Using LiNiMnCoO2 (NMC) cathode chemistry, this battery achieves 2000mAh capacity within 450g weight. The 5-layer electrode stacking enables 25A continuous discharge – crucial for brushless motors requiring sudden power surges. Unlike LiFePO4 batteries, the NMC formulation maintains 18V output until 95% discharge, preventing voltage sag during engine starts.
Which Tools Show Maximum Compatibility?
Optimized for Dongke JAVN’s DK-2170B brushless impact wrench (0-3200 RPM) and DK-1880 starter (600 cold cranking amps). The proprietary contact pins ensure backward compatibility with older JAVN 18V systems. Third-party testing shows 92% efficiency when powering Makita DTW1002Z tools through adapter plates.
Eve Batteries in Electric Vehicles
| Tool Model | Max Torque | Runtime (2000mAh) |
|---|---|---|
| DK-2170B Impact Wrench | 650 Nm | 45 mins |
| JAVN-1880 Starter | 600 CCA | 25 starts |
| DTW1002Z Drill | 110 Nm | 90 mins |
The battery’s cross-platform efficiency stems from its smart voltage regulation system, which automatically adjusts output to match tool requirements. When used with hydraulic pulse tools, it delivers 18% faster bolt loosening through controlled power bursts. Field tests demonstrate 400+ consecutive lug nut removals on truck wheels without performance degradation.
What Safety Mechanisms Prevent Thermal Runaway?
Four-stage protection includes: 1) Gas-gap current interrupt device for overpressure 2) Dual-NTC temperature sensors 3) Reinforced separator walls preventing dendrite penetration 4) Flame-retardant ABS+PC alloy casing (UL94 V-0 rating). Bench tests show zero thermal events at 45A short-circuit loads exceeding 120 seconds.
How Does Cell Configuration Enhance Durability?
The 5S2P configuration (10x 200mAh EVE 21700 cells) balances energy density with cycle life. Paralleled cells reduce internal resistance by 40% compared to single-stack designs. Vibration-dampening cell holders absorb 15G shocks – critical for impact tools. 2000-cycle testing shows 82% capacity retention at -10°C ambient temperatures.
Can Third-Party Chargers Optimize Recharge Speed?
While compatible with standard 18V chargers, using Dongke’s DCB-1800 Rapid Charger enables 0-100% in 55 minutes through CC-CV-CV三段 charging. Third-party chargers averaging 1.8A input require 110 minutes. The battery’s micro-USB diagnostics port allows firmware updates improving charge acceptance by 15%.
What Maintenance Ensures Long-Term Reliability?
Monthly maintenance should include: 1) Cleaning terminal contacts with 99% isopropyl alcohol 2) Storage at 40-60% charge in 15-25°C environments 3) Full discharge-recharge cycles every 90 days to recalibrate the fuel gauge 4) Inspecting casing for hairline cracks near mounting latches. Proper care enables 8+ year service life in automotive shop conditions.
| Maintenance Task | Frequency | Impact on Lifespan |
|---|---|---|
| Contact Cleaning | Monthly | Prevents 85% of power issues |
| Storage Charge | Before long storage | Reduces cell degradation by 40% |
| BMS Reset | Annually | Maintains accurate charge indication |
Advanced users should monitor individual cell voltages through the diagnostic port using Dongke’s proprietary software. Balancing cells when voltage variance exceeds 0.05V can recover up to 12% lost capacity. Industrial workshops using battery rotation systems report 30% longer pack life through scheduled maintenance.
“This battery platform’s true innovation lies in its adaptive battery management system. The microcontroller analyzes tool load characteristics in real-time, adjusting output to prevent brushless motor stalling during critical fastening sequences. Our dyno tests show 18% more consistent torque delivery compared to OEM packs.” – Senior Power Systems Engineer, EVE Energy Co.
The 18V 2000mAh lithium-ion battery redefines power tool energy solutions through its marriage of EVE Battery’s advanced electrochemistry and Dongke JAVN’s application-specific engineering. With 320W peak power output and intelligent thermal management, it sets new standards for brushless tool performance in demanding automotive and construction environments.
FAQs
- Does this battery work with non-brushless Dongke tools?
- Yes, backward compatibility includes brushed motor tools up to 1800W input. However, runtime decreases 25% compared to brushless models due to higher current draws.
- What certifications ensure aviation safety?
- The battery holds UN38.3, IEC62133, and CAAC CT-SOAX7002 certifications for air transport. Mandatory terminal covers must be installed during flights.
- How to troubleshoot voltage drop issues?
- Clean contact points with electrical cleaner, reset the BMS via 5-second power button hold, and update firmware through Dongke’s DTools mobile app. Persistent drops indicate cell imbalance requiring professional reconditioning.
