Unlike standard residential electronics, which operate at around 60 volts, low voltage batteries work with power under 60 volts. The effect of this is an increase in safety, opening doors to applications such as residential backup power, small solar systems, and portable electronics. Low voltage batteries come in various types including lithium-ion, lead-acid, and nickel-cadium batteries. Each battery offers distinct advantages in terms of energy density, cycle life, and cost. As a whole, low voltage batteries are a reliable power access resource even in cases with low power demand.
