Vapcell K31 18650 3150mAh 18A Continuous 35A Max Flat Top Li-ion Battery (2 pcs)
Product Overview
An individual Vapcell cylindrical rechargeable lithium-ion cell for equipment and properly engineered battery assemblies designed around its electrical and physical requirements. Select the exact model rather than relying on the 18650 size alone.
Key Features
Product Specifications
| Brand | Vapcell |
| Model | K31 |
| Battery chemistry | Rechargeable Lithium-ion (INR) |
| Cell format | 18650 |
| Nominal voltage | 3.6V |
| Nominal / typical capacity | 3150mAh typical |
| Rated / minimum capacity | 3050mAh minimum |
| Current rating | 18A maximum continuous; 35A maximum discharge (not continuous) |
| Positive terminal | Flat top |
| Physical dimensions | Ø18.4 × 65.2 mm |
| Cell weight | Approx. 48g |
| Charging requirements | 4.20V CC/CV; 1.5A standard / 4A quick charge |
| Discharge cutoff / test condition | 2.5V |
| Rechargeable | Yes |
Suitable Applications
- High-drain 18650 battery packs designed for K31 characteristics
- Professional replacements where K31 is the specified cell model
- Compatible devices requiring a flat-top lithium-ion cell
These are application examples only. Confirm the equipment manufacturer's specified cell model, electrical requirements and terminal design.
Check Before Ordering
Check original model/markings, positive terminal shape, physical length, chemistry, nominal voltage, charge profile, maximum continuous discharge rating and protective circuitry. Matching the 18650 size alone does not confirm electrical or mechanical compatibility.
Charge using equipment explicitly configured for single-cell lithium-ion CC/CV charging. The correct charge voltage is provided in the specifications where verified.
Safety: These are individual rechargeable lithium-ion cells, not finished consumer battery packs. Use only in equipment or professionally engineered packs with suitable charge control, battery protection, short-circuit prevention and temperature management. Do not carry cells loose with keys or metal items, short-circuit, puncture, crush, dismantle, expose to fire, or charge unattended. Do not mix cells of different type, age, capacity or state of charge. An 18650 Li-ion cell is NOT a substitute for a 1.5V AA battery.
Package Includes
2 × Vapcell K31 batteries. Chargers, holders, wires, welding tabs and equipment are not included unless separately shown as included.
Warranty
12 Month LANplus Return-to-Base Warranty for eligible manufacturing faults. Correct cell handling, installation and protection are essential. Australian Consumer Law rights continue to apply.
