When on, tap to cycle 30% → 60% → 100% → 30%. Hold to switch power; releasing after a hold does not change the brightness level.
Keyboard: Enter or Space to tap / hold. When off, hold to turn the light back on.
Lighting illustration only, not measured light output. The demo starts at 100%; one short press selects 30%. Hold timing and the restart brightness of the actual product are confirmed for the selected configuration.

↓APPLICATION FIRST
Rechargeable LED Lighting and Three-Level Dimming
The battery-box example combines a rechargeable battery, charging and dimming board, and a connected LED light strip. It can be reviewed for portable illuminated products such as the supplied bag application. Match the lighting load, battery and enclosure to the selected configuration.
IMPORTANT CONNECTION WARNING
Not a power bank.
Do not connect this battery box to other rechargeable devices. Do not use it to charge phones, tablets, power banks or other rechargeable equipment. The Type-C output is 3.7–4.2V for the intended lighting load, not a general-purpose 5V USB charging output.
BATTERY-POWERED LIGHTING
From the battery box to the light.
Assembly views and an illuminated product application. The two assembly photographs have been edited to a white background; the bag photograph is supplied application material, not a runtime or brightness test.
SWITCH & TYPE-C PORT

Hold duration, battery capacity, charging time and current ratings are not specified. Confirm these details for the selected configuration.
DEFINE BEFORE DESIGN
Battery, Charging Input and Lighting Load
Confirmed requirements, preferred targets, and open questions can all be included in the first brief. Unknown values stay visible until they are reviewed.
Input source
Supply type, voltage range, connector, available power, negotiation requirements, polarity, and transient conditions.
Charge profile
Target current and voltage, pre-charge, termination, recharge behavior, timing, and any cell-maker limits.
Product power path
Charge-only or charge-while-operating behavior, load sharing, cutoff states, standby current, and power sequencing.
Protection & thermal
Temperature sensing, current and voltage limits, reverse conditions, short-circuit behavior, heat path, and enclosure.
Interface & validation
Indicators, buttons, host communication, logging, acceptance criteria, test method, and applicable compliance review.
PROJECT FIT
Battery Box and Charging Board Integration
A useful first review separates confirmed battery limits from desired product behavior and unresolved compliance questions.
New rechargeable product
Coordinate the pack, input, charging, load, indicators, enclosure, and thermal path.
USB-C input revision
Review the actual power requirement and negotiation scope before changing the connector or source.
Existing board update
Address form factor, heat, indicators, standby behavior, connectors, or component availability.
Host-connected charging
Define status signals, control commands, fault reporting, and power-state ownership.
CONTROLLED DEVELOPMENT PATH
From project brief to approved handoff.
A review result, prototype, or sample remains a project stage. Production begins only from the information and acceptance criteria approved for that project.
- 01
Requirements review
Confirm the application, functions, electrical limits, interfaces, mechanical constraints, quantity, and open questions.
- 02
Architecture & prototype
Develop the agreed circuit, PCB layout, firmware scope, connectors, and prototype route.
- 03
Evaluation & revision
Check the agreed functional, electrical, thermal, communication, and fit criteria, then record revisions.
- 04
Production handoff
Release only the approved design, component, firmware, assembly, inspection, and packing information.

PROJECT QUESTIONS
Before the first technical review.
These answers describe how a project can begin. They do not promise an unreviewed specification, performance result, certification, schedule, or price.
How do I turn the battery box on or off?
Press and hold the battery-box switch to turn power on or off. The required hold duration is not specified.
How many brightness levels are available?
Short press the battery-box switch to cycle through three brightness levels in this order: 30% → 60% → 100% → 30%. Press and hold to turn power on or off.
What are the Type-C input and output voltages?
Charging input is 5V. In output mode, the specified voltage is 3.7–4.2V. Confirm the intended lighting load and cable arrangement before connection.
Can I use the battery box as a power bank?
No. Connecting the battery box to other rechargeable devices is prohibited. It must not be used to charge phones or other rechargeable equipment.
Does a USB-C connector mean the board supports USB Power Delivery?
No. Connector shape does not establish the negotiated voltage, current, protocol, cable requirement, or available power. Those functions must be specified and verified.
Can the product operate while the battery is charging?
It may be possible, but the load profile, input capacity, power-path architecture, battery limits, heat, fault behavior, and user expectations must be reviewed.
Is battery protection included?
Protection may be on the cell pack, the charging board, or both. The responsibility and limits of each protection layer must be defined before design approval.
What is needed for an LED battery-box controller review?
Provide battery chemistry, cell count, capacity, voltage limits, permitted charge current, pack datasheet, protection details, connector, temperature sensor, LED load and target operating conditions. Confirm the enclosure and requested dimming behavior for the selected configuration.
