Its durable and quiet operation makes it an essential addition for any battery-powered setup. ## Description Lead-acid batteries produce hydrogen gas when charging. But if the battery box is left open to vent gas in cold climates, the batteries get too cold and battery capacity is significantly reduced. A vent that solves this problem is especially important when battery boxes are placed in basements, garages and sheds. When heat rises in the structure, a low pressure area forms around the box, cool air flows into the box and gases vent into the structure. The Power Vent controls battery box venting, removing dangerous hydrogen gas while reducing cold air infiltration into the box. The Power Vent contains a gravity-operated damper that normally stays closed. When connected to a voltage-controlled relay, the fan operates only when the batteries are being charged and blows gas vapors out. Designed for battery banks under 2200 Ah and charge rates under 125 amps. Fan can be operated from the auxiliary relay on a Xantrex XW inverter, from the auxiliary relay of an OutBack FX inverter (use 12 volt-fan for all OutBack inverter voltages) or by a voltage controlled switch. The 12/24-volt unit uses 3 watts and pushes air at 6 CFM with a 360° maximum change of direction. Dimensions: 4" diameter x 7.25" with a 2" PVC pipe socket on the inlet and outlet. The 48-volt unit uses 6 watts and pushes 8 CFM with a 360° maximum change of direction. Dimensions: 4" diameter x 10" long, with a 3" PVC pipe socket on the inlet and outlet. ## Features - The Power Vent controls battery box venting, removing dangerous hydrogen gas while reducing cold air infiltration into the battery box. ## Product Details - **Brand:** Power Vent - **Color:** White - **Power Source:** Battery Powered - **Style:** Modern - **Wattage:** 3 watts - **Included Components:** Cord - **Blade Material:** Plastic - **Manufacturer:** Zephyr Industries ## Images ![Zephyr Power Battery Box Vent Fan - 12 Volt DC White - Image 1](https://m.media-amazon.com/images/I/4187q6blzgL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Works great with an Outback FLEXmax 60/80 charge controller *by H***K on Reviewed in the United States on June 17, 2018* I purchased the Zephyr Power Vent for a 24V off-grid solar battery bank, which consists of eight flooded deep cycle batteries. Setting my Outback FLEXmax 80 aux relay to "Vent Fan" and an "ON" charge voltage of 27 volts, the power vent works great!NOTE: if you are buying a Zephyr power vent fan for an Outback FLEXmax charge controller, make sure to purchase the 12V fan. The FLEXmax output only 12VDC to the fan irrespective of the battery bank voltage. ### ⭐⭐⭐⭐ 4.0 out of 5 stars Smooth, quiet and powerful. *by S***I on Reviewed in the United States on March 12, 2019* Quiet operation. Moves plenty of air.The flapper inside was rendered inoperable due to mounting upside down to direct ducting downwards. Works well so far though. ### ⭐ 1.0 out of 5 stars Didn’t last long *by K***L on Reviewed in the United States on October 3, 2022* I had one of these specific vents added to my battery boxes for my solar, it didn’t last twelve months. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/64419637-zephyr-power-battery-box-vent-fan-12-volt-dc-white](https://www.desertcart.be/products/64419637-zephyr-power-battery-box-vent-fan-12-volt-dc-white) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-10-26*
