BMAX BH-18650-04 Bay Battery Charger

The BMAX BH-18650-04 is a compact 4-bay smart charger for rechargeable lithium-ion cells from BMAX, a budget consumer electronics brand.

Quick answer
BMAX 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.200/day with same-day Colombo delivery. A refundable security deposit applies.

Charges up to four cylindrical Li-ion cells at once, with each bay running independently at 4.2V/1000mA.

USB 5V input lets you power it from a mains adapter, power bank, laptop, or vehicle port, and the spring-loaded slots handle sizes from 10440 to 18650.

AV crews and event teams use it to keep wireless mic beltpacks, LED on-camera lights, monitor batteries, intercom packs, and head-torches running through long shoots.

Red and green LEDs per slot show charging status at a glance, so you can rotate cells without guessing when they are ready.

Why Choose This Product

  • Wide cell compatibility: Accepts 10440, 14500, 16340, 14650, 16650, 18350, 18500 and 18650 Li-ion cells in the same cradle, so one charger services multiple device types in a kit.
  • Four independent channels: Each bay charges on its own circuit, so partially used and fully drained cells can sit side-by-side without one slowing the others.
  • Per-slot status LEDs: A red/green indicator on every bay shows charging vs full at a glance, useful when rotating cells between devices during a live event.
  • USB 5V input: Runs from any standard USB port, mains adapter, or power bank, so the charger does not need a dedicated mains outlet on a crowded AV rack.

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.
