  • 【Integrated Design with Easy Installation】This lithium battery box is designed with 4 slots for 18650 batteries, featuring KF8500-8.5 terminals integrated into a PCB board. The design allows for hassle-free installation and removal without soldering, using just a screwdriver to secure wiring. This provides a seamless experience for both beginners and professionals handling battery packs.
  • 【Flexible Wiring Options for Custom Setups】Our battery holder supports versatile configurations, allowing batteries to be connected in series or parallel. You can set up configurations like 4 in series, 4 in parallel, or mixed setups like 2 in series followed by parallel. This flexibility lets you tailor the power bank to specific voltage and capacity needs, ensuring optimal performance for various applications.
  • 【Enhanced Capacity and Voltage Management】By using the 4 parallel connection method, the battery box maintains voltage while quadrupling capacity. Alternatively, the two parallel followed by two series configuration doubles both capacity and voltage. Such customization ensures that your power bank aligns precisely with your energy requirements, maximizing efficiency and functionality.
  • 【Compatibility with Protection Boards】The battery case is compatible with 1 to 4 lithium battery protection boards, allowing for safe and efficient operation. This compatibility ensures your battery pack remains protected against overcharge, over-discharge, and short circuits, providing peace of mind and extending the lifespan of your power bank.
  • 【User-Friendly Design for Secure Connections】Each battery slot is individually linked to the terminals, ensuring secure and independent connections. With a focus on safety, the design requires consistent wire thickness when connecting in series and parallel. The 3mm mounting holes further facilitate secure installations, enhancing reliability during use.
