Heltec 10-120V 1-150A High Power Battery Capacity Tester Discharge Load Tester for Li-ion/Lead-acid Battery Packs

Heltec HT-DC150ABP High-Power Battery Capacity Tester (Discharge)

The HT-DC150ABP High-Power Battery Capacity Tester is a professional-grade discharge tester designed for finished battery packs with built-in BMS protection boards. It supports a wide range of battery types, including lead-acid, LiFePO4, ternary Li-ion, and NiMH batteries, with adjustable voltage from 10V to 120V and discharge current from 1A to 150A (max 150A for ≤100V, max 100A for >100V). Ideal for battery manufacturing, repair, energy storage testing, and lab/service applications, this tester delivers precise, real-time monitoring with high accuracy and versatile discharge modes.

Key Features

• Wide Compatibility: Supports 10-120V battery packs (lead-acid, LiFePO4, ternary Li-ion, NiMH) with BMS protection boards.

• High-Power Discharge: Adjustable current from 1-150A (0.1A step), max 150A continuous discharge for ≤100V systems.

• Precision Monitoring: ±0.1% voltage accuracy, with real-time display of voltage, current, capacity (Ah), and energy (kWh).

• HD Touchscreen: 7-inch color touchscreen for intuitive operation, multiple data display, and quick mode selection.

• Multiple Discharge Modes: Constant voltage, periodic, and fixed-capacity discharge modes to meet diverse testing needs.

• Comprehensive Safety Protection: Over-voltage, over-current, over-temperature, reverse connection, and high-temperature alarm protections.

• Easy Mobility: 360° swivel casters with low-noise rolling and locking design for flexible placement.

• Robust Wiring: 150A-rated heavy-duty cables with positive/negative clamps and temperature detection ports.

Specifications

Product Structure & Ports

Power Switch: Turns the tester on/off.

Emergency Stop Switch: Immediately cuts off power for safety protection.

How to Use

1. Power On: Turn on the tester using the power switch.

2. Connect the Battery: Attach the positive/negative clamps to the corresponding terminals of the battery pack.

3. Set Parameters: Select the battery type (lead-acid/LiFePO4/ternary/NiMH), discharge mode, and desired voltage/current settings on the touchscreen.

4. Start Discharge: Initiate the test and monitor real-time data (V, A, Ah, kWh) on the display.

5. Safety Note: Keep a 2-meter clearance around the air intake/outlet, operate in a well-ventilated area, and use the emergency stop switch if issues arise.

Heat Dissipation & Safety

1. Airflow Design: Left-side air intake and right-side air outlet for efficient cooling.

2. Clearance Requirement: Maintain 2 meters of free space on both sides to avoid overheating.

3. Safety Warnings:

• Do not block air vents; avoid operation in enclosed spaces.

• Use the emergency stop switch in case of high-temperature alarms or malfunctions.

• Operate only with battery packs that have built-in BMS protection boards.

• The tester generates significant heat during use; ensure adequate ventilation and heat dissipation.

Applications
