18650 3.7V Lithium-Ion Rechargeable Battery

The 18650 is the industry-standard cylindrical lithium-ion rechargeable cell, named for its 18mm diameter and 65mm length.

Quick answer
Power Bank is a rental accessory available through Rentitem.lk in Sri Lanka. It is used alongside other gear for Stage Power Distribution: Distribute power to mixers, lights, microphones, and speakers from one central power source.. The rental rate is Rs.100/day with same-day Colombo delivery. A refundable security deposit applies.

The 18650 carries 3.7V nominal, charges to 4.2V, and stores 1500mAh to 3500mAh depending on the cell.

Chemistries vary, with high-drain variants handling 10A to 30A and standard cells tuned for longer runtimes at lower draws.

These cells power portable LED panels, wireless mic packs, handheld torches, headlamps, and field monitors on outdoor shoots.

Crews keep multiple sets in shoot bags, rotating them through chargers to keep productions running where mains power is unavailable.

Why Choose This Product

  • High-capacity Wh Battery Capacity: Battery-powered AC outlet for outdoor / mobile setups without mains power.
  • Standard 18650 Form Factor: Cylindrical 18mm x 65mm cell compatible with the vast majority of torches, vape mods, battery sleds, and DIY pack builders that accept the 18650 footprint.
  • Wide Capacity Options: Cells are commonly available from around 1500mAh up to 3500mAh, allowing a balance between runtime and discharge current depending on the host device.
  • Series and Parallel Stacking: Cells can be combined to build higher-voltage (multi-cell series) or higher-capacity (parallel) packs for portable lighting, monitor V-mount alternatives, and custom DIY power solutions.
  • Protected vs Unprotected Variants: Many 18650s ship with an integrated PCB to guard against overcharge, over-discharge, and short circuits, while flat-top unprotected cells are used inside engineered packs with external BMS.

How Can You Use This

  1. Stage Power Distribution: Distribute power to mixers, lights, microphones, and speakers from one central power source.
  2. AV Rack Setups: Powering a rack of audio mixer, wireless receivers, and a computer monitor at the FOH position.
  3. Office and Conference: Extra outlets at presenter tables, meeting rooms, and shared workstations.
  4. Outdoor Events (with Inverter / UPS): AC power at sites without grid - weddings on lawns, beach setups, outdoor exhibitions.
  5. Equipment Protection: Surge protectors and power conditioners shield sensitive audio / video equipment from line spikes.
  6. Sequenced Equipment Power-On: Avoid amp pops and breaker trips when turning on a full AV rack - sequencers power up devices in order.
