SPIDER Automation | 4x 18650 Battery Holder | 14.8V 4S Series Open-Frame Assembly
The SPIDER Automation 4x 18650 Battery Holder is designed to arrange four cylindrical lithium-ion cells into a 4S series battery configuration. It provides a structured mounting platform for assembling a battery pack with an approximate nominal voltage of 14.8V and a fully charged voltage of 16.8V when used with conventional 3.7V nominal lithium-ion cells.
The open-frame design provides direct access to the battery positions, while the integrated wire leads offer a connection interface for external circuits. This holder is intended for custom battery pack construction and electronic projects where a four-cell series arrangement is required.

Connection & Operating Recommendations
A four-cell series battery assembly requires appropriate cell matching, charging control and protection. Use this holder as part of a properly designed 4S lithium-ion system, with the charging and load connections configured for the electrical requirements of the complete battery pack.
- Cell Matching: Use four compatible 18650 cells with the same chemistry, nominal capacity and similar condition. Avoid mixing new, aged or differently rated cells.
- Battery Protection: Incorporate a suitable 4S lithium-ion BMS with correctly configured cell connections and protection functions for the intended load.
- Charging System: Use a dedicated 16.8V CC/CV charger designed for a conventional 4S lithium-ion battery pack. Do not charge the pack using a 12V or unregulated power supply.
- Polarity and Wiring: Confirm the battery terminals and wire polarity before connecting the assembly to a BMS or external circuit. Follow the protection board’s documented connection diagram.
- Load Compatibility: Select the connected equipment and wiring according to the cells’ discharge ratings, expected operating current and startup current.
- Mechanical Protection: Since the holder has no cover, provide suitable external protection against accidental contact, conductive debris and mechanical damage in the finished assembly.
- Voltage Regulation: Use an appropriately rated DC-DC converter when the connected electronics require a regulated supply different from the battery pack voltage.
