Rechargeable Li-FePO4 Batteries (6x)

These are our recommended rechargeable lithium batteries for standard use. 

These lithium iron-phosphate (Li-FePO4) have great discharge characteristics and cycle life.  They are also more stable than lithium-ion batteries.  A single set of six batteries will give OpenROV 2-3 hours of continuous operation.  For multiple back-to-back or extended dives, additional sets or high capacity batteries are recommended. 

We strongly advise that you review this Battery Safety Information Page prior to handling Lithium-containing batteries.
