5V Boost Converter Lithium Battery Charging Module with Fast Protection Display USB 134N3P

5V Boost Converter Lithium Battery Charging Module with Fast Protection Display USB 134N3P Description

Product overview A compact charging and boost module designed for single cell lithium battery systems. Provides 5V output from a 3.7V battery input while handling charging, discharging, and multiple builtin protections to simplify battery powered projects. Key benefits Reliable battery management: Integrated charge and discharge management with builtin MOSFET switching makes safe charging and discharging straightforward. Stable 5V output: Boosts battery voltage to a regulated 5V output at up to 1A for powering USB devices or small electronics. Comprehensive protection: Overcharge, overdischarge, overvoltage, short circuit, heavy load, and overtemperature protections are integrated to protect battery and load. Low idle drain: Maximum standby current of 8uA reduces battery drain when the module is not active. Clear status feedback: Charge and discharge status indication helps with setup and diagnostics. Main features Color: Micro; Color: White Type: Module to improve conversion rates Input voltage: 3.7V to 5.5V Output voltage: 5V Charging current: up to 1A Output current: up to 1A Preset charging voltage: 4.2V with an accuracy of plus or minus 1 percent BAT discharge termination voltage: 2.9V Discharge efficiency: 85 percent when input is 3.7V and output is 5V at 1A Maximum standby current: 8uA Builtin charging and discharging MOSFETs Integrated protections: overcharge, overdischarge, output overvoltage, short circuit, heavy duty protection, and overtemperature protection Supports turbulence mode zero voltage charging Charge discharge status indication Equalizing voltage: 3.0405V Equalizing current: 60mA Supply voltage nominal: 5V 1A Short circuit protection: yes How it solves common problems Eliminates the need for separate charger and boost circuits by combining charging, protection, and boost conversion into one module. Prevents battery damage from overcharge and overdischarge with preset thresholds and integrated protection circuits. Reduces unintended battery drain with very low standby current for longer idle life. Simplifies diagnostics and installation with clear charge and discharge status indicators. Compatibility and usage notes Designed for single cell lithium battery systems within the input voltage range of 3.7V to 5.5V. Output is regulated to 5V and supports loads up to 1A. Suitable for projects that require both charging and regulated 5V output from a single cell battery and where integrated protection is needed. Typical applications Portable USB power modules for small devices and DIY power banks that need a regulated 5V output and managed charging. Battery backup for microcontroller projects and IoT devices where safe charging and low standby current are important. Replacement or upgrade module in portable electronics and hobby projects that require integrated protection, status indication, and boost conversion.
