Powering the SoundAdvisor Model NMS044

The SoundAdvisor Portable System is offered with a choice of a traditional lead acid (SLA) battery or a Lithium Iron Phosphate (LiFePo) battery. LiFePo batteries recognize a significant improvement over Lithium ion technology, offering extended life of over 2500 recharge cycles and safer automation. The LiFePo battery provides high capacity at half the weight of a comparable SLA battery with a longer life and great low temperature performance.

To accommodate use in both common and harsh solar conditions, the SoundAdvisor Kit can be configured with one of two different portable solar panels.
