ATORCH BW150 Adjustable Constant Current Electronic Load and Battery Tester

The ATORCH BW150 is a smart 150W adjustable constant-current electronic load and battery tester. It features a broad voltage range (1V to 200V) and discharge currents up to 25A. Its standout features are its Tuya Wi-Fi and Bluetooth connectivity, which allow for remote monitoring via the E-test app Core Characteristics Power Capacity: Handles a maximum discharge/load capacity of 150W. Voltage & Current Ranges: Operates seamlessly across DC 1V - 200V with continuous current adjustments ranging from 0.1A - 25A. Measurement Modes: Supports Constant Current (CC), Constant Voltage (CV), Constant Resistance (CR), and Constant Power (CP) modes. 4-Wire Measurement: Designed with a 4-wire interface to eliminate voltage drop over test leads and ensure highly accurate battery capacity and internal resistance readings. Smart Connectivity: Built-in Tuya Wi-Fi and Bluetooth enable real-time monitoring and data logging (V, A, W, Ah, Wh) via iOS/Android apps or a PC Pros & Cons from User Reviews Pros: Highly versatile for testing various battery types (Lead-Acid, Li-ion, LiFePO4), detailed graphing via mobile/PC software, excellent value for hobbyists and DIY electronics repairs. Cons: The active cooling fan is known to run loudly during operation; under extended heavy loads at 150W, the unit can get quite warm, requiring strict adherence to its thermal and current thresholds
