4 Inch Color Touchscreen CNC Electronic Load 150W 20A DC Battery Capacity Tester With 4 Wire Kelvin Sensing For Heavy Duty LiFePo4 Cell Aging Tests And Hassle Free Straight Up Precision Testing

Precision DC Load Module For Battery Capacity
✔️ Covers 0 to 150 volts while supporting steady 20 amp draws

This digital DC load analyzer lets you run consistent discharge cycles to verify battery endurance under real conditions. You will find it pretty handy in workshops where LiFePO4 packs need routine health checks and capacity mapping.

✅ True Kelvin four wire setup removes lead resistance errors
✅ Steady twenty amp draw matches cell aging test requirements
✅ One fifty watt peak handle large storage banks without strain
✅ Safety circuits shut down power when temperature hits limits
✅ Built in fan cools down fast once three amp flow picks up

💡 What causes inaccurate capacity readings during battery cycle testing?

- Loose test leads introduce stray voltage drops across the circuit
- Thermal drift inside the unit skews the displayed efficiency numbers
- Using four wire sensing cables and locking your set amperage keeps measurements rock solid
