NexSens Buoy Battery Capacities


NexSens data buoys will have differing battery capacities depending on the buoy size and integrated battery harness. One or multiple batteries (connected in parallel) can be installed. Multiple batteries wired in parallel provide the same 12.0-14.9V required to power NexSens data loggers and external sensors. However, the Amp hour capacity increases by 28A-hr with each added battery. NexSens offers three standard types of battery harnesses that include: sealed lead acid batteries, a solar regulator, mounting bracket posts, and a data logger connection cable pigtail (UW-6 connector).

*Since all batteries are wired in parallel, the nominal voltage is 12VDC for all battery harnesses.
**Approximate weight only includes the total weight of the batteries.
***The length and width of harnesses with multiple batteries will remain the same as the batteries are stacked.
(CB-A01-2: Length = 5.94″/150.9mm ; Width = ~6.5″/165.1mm), (CB-A05-x: Length= 6.64″/168.7mm; Width = 7.05″/179.1mm).
