Alligator Clips to Powerpole Connector
For connecting the ROV power cord (with powerpole connectors) to a car or marine battery:
12 volt Deep-Cycle Marine/RV car battery:
Large lead acid batteries are another way to power the ROV. MATE recommends the Deep-Cycle Marine / RV battery, as they are designed to be run down and recharged many times (a standard 12 volt car battery is not designed for this). The battery should be able to run a PufferFish ROV for 4 to 6 hours or you can run 3 ROVs at a time for an hour or more. The battery will need to be recharged after that. To recharge a car type battery, you will need to purchase a charger.
The battery will also need an adapter for the Powerpole connectors from your ROV to plug into. This adapter has Alligator clips that connect to the battery posts on one end and has Powerpole connectors at the other end.
