BT2.0 Battery Charger and Voltage Tester V2 (Type-C Input) Dual 1S Charger, 4.35V/1A Output

Overview

The BT2.0 Battery Charger and Voltage Tester V2 is a compact battery charger and cell voltage tester designed for BT2.0 series 1S batteries. Compared with the first version, V2 upgrades the input to a Type-C port and uses a hidden-style electric display and charging indicator for a cleaner look.

Key Features

• 2-in-1 design: charging and 1S cell voltage checking
• Type-C input for flexible powering options (e.g., power bank, laptop, or USB plug)
• Dual outputs: OUT1/OUT2 can charge simultaneously (power-on)
• Status indication: red = charging, green = full charged
• Power-off mode: OUT1 works as a battery tester; OUT2 has no function
• Charging reference times: BT2.0 300mAh battery fully charged in 20 minutes; BT2.0 450mAh 1S battery fully charged in 30 minutes
