8 sold in last 24 hours
The TP5000 Lipo charging module is a compact, high-efficiency module designed to charge both 3.7V lithium-ion and 3.2V lithium iron phosphate (LiFePOâ‚„) batteries. It supports a selectable charging voltage of 4.2V or 3.6V, adjustable via a simple solder pad configuration.
Features:
- Supports charging of both Lithium-ion and LiFePOâ‚„ batteries
- Auto cutoff when charging completes, protecting the battery from overcharge
- Selectable output voltage(4.2V for Li-ion, 3.6V for LiFePOâ‚„) via solder jumper
- Dual LED charge indicators(Red for charging, Green for full)
- Compact design, suitable for integration into DIY electronics projects
- Performance version supports up to 2A fast charging
- User-configurable charge current via resistor.
