Description
18650 Lithium‑Ion Battery Holders are safe, rugged and reliable for 3.7V 18650 cylindrical cells. One can choose between a Single‑Slot (1‑Slot / 3.7V) or a Dual‑Slot (2‑Slot / 7.4V Series) version. These holders have heavy‑duty molded ABS enclosures and high‑tension spring‑steel terminal contacts.
Each holder comes with color‑coded 150 mm wire leads that make soldering or breadboard connections quick and easy. So anyone can use them as a baseline power source for embedded microcontrollers, robotics platforms, portable lighting and custom power bank enclosures.
Key Features & Benefits
- Cell Compatibility: The 18650 Lithium‑Ion Battery Holders fit both flat‑top and button‑top 18650 cylindrical Li‑ion cells.
- Dual Output Options:
- 1‑Slot: The 18650 Lithium‑Ion Battery Holders give a single‑cell 3.7V output (4.2V when fully charged).
- 2‑Slot (Series): The 18650 Lithium‑Ion Battery Holders give a dual‑cell 7.4V output (8.4V when fully charged).
- High‑Tension Spring Contacts: Nickel‑plated leaf and coil spring contacts keep a clamping force so the 18650 Lithium‑Ion Battery Holders do not disconnect when shocked or vibrated.
- Color‑Coded Flying Leads: Pre‑tinned positive) and black (negative) 24/26 AWG wires let me install the 18650 Lithium‑Ion Battery Holders quickly with the correct polarity.
- Integrated Mounting Holes: Pre‑drilled countersunk screw channels on the base let me mount the 18650 Lithium‑Ion Battery Holders flush and securely inside device housings.
- Impact‑Resistant ABS Shell: The rigid heat‑resistant plastic casing of the 18650 Lithium‑Ion Battery Holders protects the battery cells, from damage and external short circuits.
