Battery Level Indicator Module
Detailed Features
- Intuitive Display: It uses 5 LED segments to show capacity. Typically, the first segment (a battery frame) indicates power is present, while the four bars represent 25%, 50%, 75%, and 100% charge.
- One-Touch Operation: It features a red “TEST” button. You press it to trigger the display, which then stays lit for about 3–10 seconds before auto-extinguishing to save power.
- Safety Built-In: Most versions include reverse connection protection, meaning if you accidentally swap the red and black wires, the module won’t burn out.
- Universal Compatibility: Depending on the specific sub-model, these can be used with:
- Lithium-Ion/LiPo: 1S (3.7V) up to 8S (29.6V).
- Lead-Acid: 12V or 24V batteries
