Klvr is launching in the United States with a professional-grade rechargeable battery solution designed to cut costs and improve performance across live entertainment and pro AV markets. Klvr Charger Pro enables stage managers, audio engineers and AV professionals in music venues, houses of worship, broadcast studios, conference halls and universities to eliminate the cost of single-use batteries. The solution is now available across the country from pro audio rental and AV integration partners including MBH Solutions, The Penn Group, and YAP Technologies.
Tracy Dietrich, COO of specialist audio, visual and lighting distributor MBH Solutions says, “We’re very excited about partnering with Klvr. We feel the brand will be a strong addition to our offerings, providing customers a simple, flexible and cost-effective way to power multiple pro audio devices while reducing battery waste. We look forward to building the relationship.”
Founded by sound engineers and music artists, Klvr’s rechargeable battery solution is purpose-built for professional audio. It offers venues and AV teams a cost-effective way to power wireless microphones, in-ear monitoring and other devices that are widely compatible with standard AA/ AAA batteries. It has been deployed by a range of organizations to eliminate the costs of thousands of disposable batteries while increasing performance and efficiency, including Norwegian state broadcaster NRK – Norwegian Radio Orchestra (KORK), Greek broadcaster Alpha TV, UK audio rental specialist Handheld Audio, and Mikael Svensson, backline engineer at Overkill Backline for artists including Per Gessle and the four-time US Billboard Hot 100 number one single chart-topping pop rock duo Roxette.
“We've had problems getting full value out of alkaline batteries – they often get thrown away when they're only half empty. We looked at proprietary chargers, but they're often very expensive and lock us into a single brand,” says Knut Fredrik Valsgård, technical advisor at OKS Romerikskirken, Oslo Kristne Senter (Oslo Christian Center). “The Klvr system gives us confidence that we're always putting in fully charged batteries that will last through both soundcheck and the full service. We're saving over 2,000 batteries from landfill every single year.”
“While proprietary solutions from major manufacturers can be costly and incompatible with devices from different suppliers, commonly available consumer-grade rechargeables fail to deliver the reliability and voltage required in professional environments,” the announcement states. “Klvr Charger Pro provides a simple, flexible and affordable solution, comprising a lightweight, 19” rack-mounted charger with capacity for 48 high-performance, standard-sized AA and AAA batteries for any device.”
Klvr’s custom 1.5V Li-Ion batteries are each designed for 1200 charging cycles and a 30% higher runtime than regular commercial rechargeables. “By using one pack of 48 Klvr batteries to their full lifetime capacity, AV professionals can power pro audio devices every day for over 3 years and eliminate the cost of up to 57,600 single-use batteries – delivering significant financial savings over time,” the announcement continues.
“Houses of worship, concert halls and corporate venues rely on wireless mics and other devices every day, but using thousands of disposable batteries to keep them powered is expensive, unreliable and a constant headache," says Stian Sagholen, CEO and Founder, Klvr. “AV teams need pro-grade batteries they can trust in critical live environments – and that work across different devices from their favourite audio brands. Our customers in the US and globally are cutting costs, lowering their environmental footprint, and delivering flawless shows with Klvr rechargeables.”
Klvr batteries’ long runtime and linear discharge curve eliminate the guesswork of consumer-grade rechargeables. Its Klvr Control system provides full visibility into battery life, helping AV professionals smoothly check battery levels, recharge times and adjust settings from connected laptops. Klvr Charger Pro also includes a 48-battery capacity Klvr Pouch for touring, air travel, or transport to remote production locations.
The company’s US expansion builds on growing end user deployment and multiple new distributor agreements across major global markets. Klvr Charger Pro is available to purchase here: https://klvr.no/quote
