18650 battery boxes
Easy installation and removal of 18650 batteries.
Screwdriver use for wire management, no soldering required.Each battery box corresponds to a separate terminal.Accommodates up to 4 18650 batteries simultaneously.
- four parallel connection method: the total capacity of the battery becomes 4 times, the voltage is unchanged B1+, B2+, B3+, B4+ are connected, B1-, B2-, B3-, B4- are connected,and the positive poles of the batteries are facing the terminals when they are installed.
- first two parallel and then two series connection method:the total capacity of the battery becomes 2 times, the voltage becomes 2 times.B1+ is connected to B2+, B3+ is connected to B4+,B1- is connected to B2-, B3- is connected to B4-, B2- is connected to B3+,and the positive poles of the batteries are facing to the terminals when they are installed.
- four series connection method: the total capacity of the battery remains unchanged,the voltage becomes 4 times B1-connected to B2+, B2-connected to B3+, B3-connected to B4+,the positive poles of the batteries are facing the terminals when installing.
- Two strings and then two parallel connection method:the total capacity of the battery becomes two times, the voltage becomes two times.
- Flexible wiring can be performed to allow the battery pack to be connected in series and parallel,such as 4 in series, 4 in parallel, 3 in series, 3 in parallel, 2 in series, 2 in parallel,two in parallel and then two in series, and two in series and then two in parallel.
Connection options: 4 series, 4 parallel, 3 series, 3 parallel.

KF8500-8.5 terminals.
- 18650 battery boxes and KF8500-8.5 terminals are integrated into a PCB board
- Mounting hole: 3mm

Two series then two parallel
- which is convenient for the installation and removal of 18650 batteries and the wiring of the positive and negative poles of the batteries.

Four parallel connection
- Use a screwdriver to tighten and loosen the wires directly on the terminals without soldering the wires to the PCB board.

unchanged capacity
- Each 18650 battery box corresponds to the terminal one by one and is separated from each other.Up to 4 18650 batteries can be installed.

Compact and organized PCB layout.
Designed for efficient battery pack configuration.
Positive poles face terminals upon installation.Direct terminal wire connection for easy adjustments.
Simplifies battery management and connectivity.
