Subsea Battery Operation Guide

Battery Installation
Ensure subsea battery pair has different Node IDs (32/33). Use a silicon–based lubricant when making all subsea connections. If cables are already installed, check connections and skip to step 6.

1.  Remove the float block.
2.  Disconnect port and starboard 5-pin connector chains from the power module and 5-pin extension whip (orange cable on the port side of the submersible).
3.  Locate the connector for the aft vertical thruster in the starboard 5-pin chain. Remove it and add it to the port 5-pin chain.
4.  Add the 5-pin battery connector to the chain of connections. Repeat this process for both 5-pin chains.
5.  Insert the remaining other end of the battery’s 5-pin whips through the openings of the frame above both the horizontal aft thrusters.
6.  Turn submersible on its side or upside down. Use caution if a USBL beacon is attached.
7.  Line up and insert the battery camlocks into the corresponding square openings in the lower frame (skid), ensuring the 5-pin ports are at the aft end of the submersible.
8.  Twist camlocks 90° clockwise to secure both batteries to the frame, then turn submersible right side up.
9.  Connect the battery cables to the open 5-pin battery ports.
10.  If using fiber optic tether, connect the dummy plug to the 8-pin power module whip and secure plug with threaded cap.
11.  Tuck any cable slack into the frame and replace the float block.

Turning on Batteries
When turning on the batteries, powering up one battery will automatically power up the other battery.

1.  Power up the batteries by inserting the included power wand into the center circular opening in the front of one of the batteries. Fully insert the wand into the opening for approximately one second and remove. Two audible tones should be heard from the battery, followed closely by two audible tones from the other battery.
2.  Wait several (5-10) seconds to confirm submersible power by illuminated LEDs on the Power and/or Communications modules. Both batteries are now turned on and providing power.

General Operation

1.  With the batteries mounted below the frame, be cognizant of the submersible’s deeper draft. Increase minimum altitude from bottom to avoid inadvertent grounding on the sea floor.
2.  Li-ion batteries can be used at the default power setting of 1,000 watts or greater if the mission demands it.
3.  If using NiMH batteries, reduce the power setting to 700 watts via the Home tab in the Flight View menu. This power setting will extend the flight time with little effect on piloting and accessories.

Battery Depletion

During extended periods of use, the batteries may experience excessive power drain resulting in insufficient power for continued normal use. In addition to on-screen battery

1. meters indicating low levels , signs and symptoms of insufficient power will become apparent in the control software, to include freezing of the video feed, the ribbon compass going dark, or the video feed going dark.
2. If this occurs, safe recovery of the submersible should now be the priority of the pilot. Recommended actions are as follows:
3.  Disable all Auto controls and turn off LEDs
4.  Reduce power setting to 500 watts
5. Enable all Auto controls
6.  Navigate to safety, disable Auto controls, and recover the submersible

Turning off Batteries

Turning off the batteries requires each battery to be independently powered down.

1. Insert and hold the power wand into the center opening of each battery for approximately one second to turn power off. A single audible tone should be heard when powering down.
2. Confirm power to the ROV is off and that the led lights on the power and communications modules are no longer illuminating.

Charging Batteries

Batteries must be turned off prior to charging. Batteries can be charged while attached to the submersible or while in the battery case.

1. Connect the XLR end of the cable to the XLR cable on the battery charger. Connect the 5-pin end of the cable to the 5-pin socket on the battery.
2. Once plugged in to a power source, the charger will power on. Use the two buttons to cycle through the charging profiles until the desired profile is displayed, either “NiMH sub” or “Lithium sub”. Make sure “sub” is next to the desired profile.
3. Press and hold the bottom button and release when OKAY is displayed.
4.  If CONNECT BATTERY is displayed after releasing the bottom button, press and hold the bottom button again and then release when FORCE START appears.
5. It will take a few seconds for the batteries to begin charging. The battery icon on the left side of the display will then indicate charging status. The batteries turn on while charging and will shut off automatically after 5 minutes once charging is complete.
6. After charging, remove the charging cables from the batteries. Store charger, cables, and batteries in the watertight case after they are rinsed and dry.
