Product Overview
Notes
⚠️ Discharge Curve Tip
The device’s report chart uses a 0-120V range. For low-voltage batteries (12V/24V), the curve looks flat (since voltage doesn’t change much in this wide range)—this is normal!
To check low-voltage battery discharge details, just follow the real-time voltage/current numbers on the device screen.
💡 Pro Tip
If you need to test small lithium batteries (e.g., 18650 cells), the HT-BCT50A is a more cost-effective choice!
This Heltec 5-120V 50A DC Electronic Load is a professional battery capacity tester and high-power discharger, designed for accurately measuring the performance of Lithium/LiFePO4/NMC/Lead Acid/Ni-MH batteries. Perfect for EV battery packs, solar energy storage systems, and DIY 18650 battery projects.
🔹 Key Features
