12V 36W UPS Module – 3S Lithium Battery Backup Power Board
12V 36W UPS Module – 3S Lithium Battery Backup Power Board
12V 36W Uninterruptible Power Supply (UPS) Module – 3S Lithium Battery Backup Board
Keep your network gear, security cameras, routers, and smart-home devices running without interruption. The Gaqqee 12V UPS Module is a compact DC uninterruptible power supply board that seamlessly switches between mains and battery power in the event of an outage — no reboots, no dropped connections, no lost data.
Key Features
- Automatic & Seamless Switchover: The board instantly switches to battery backup when mains power is interrupted, keeping connected devices online without any restart or disruption.
- High Output Power: Delivers up to 36W (MAX) output when the battery is fully charged — enough to power routers, IP cameras, switches, and infrared alarm systems.
- Stable 12V DC Output: Output voltage stays within 11V–13V DC, providing reliable, regulated power to sensitive electronics.
- Integrated Charge/Discharge Protection: Built-in protection circuitry safeguards your 3S lithium battery pack from overcharge, over-discharge, and short-circuit events.
- Compatible Battery Types: Works with 3S lithium cells, polymer battery packs, and 18650 battery packs (not included).
- LED Status Indicators: Supports standard 3mm common-anode red/green LEDs (customer-supplied) — red signals charging in progress, green signals full charge.
- Compact & Clean Design: Neatly arranged components in a slim, space-efficient form factor for easy integration into enclosures and DIY builds.

Frequently Asked Questions
Q: What devices can I power with this 12V UPS module?
A: This UPS module is designed for DC 12V devices such as routers, IP cameras, network switches, infrared alarm systems, and other electronics that operate at 12V and draw up to 36W total. It is ideal for smart-home setups and small networking installations that require continuous uptime.
Q: What type of battery do I need for this UPS board?
A: The board is compatible with 3S lithium-ion cells, 3S lithium polymer (LiPo) packs, and 18650 battery packs configured in a 3S arrangement. Batteries are not included. Always connect the battery as the very last step of your installation.
Q: How long will the battery backup last during a power outage?
A: Backup duration depends on the capacity (mAh) of your battery pack and the power draw of your connected devices. A larger-capacity 3S battery pack will provide longer runtime. For example, a 3S 5000mAh pack powering a 10W router could sustain several hours of operation.
Q: Can I monitor the charge status of the battery?
A: Yes — the board supports standard 3mm common-anode red/green LEDs (not included). A red LED indicates the battery is currently charging, while a green LED indicates the battery is fully charged, giving you at-a-glance status monitoring.
