[* black] The two battery packs are wired in parallel through theto the OpenROV Controller Board, so the power from each pack can be measures separately on the DB-25 connector. It's important to make sure you've wired these correctlyBoard.
[* black] Place three fully-charged 26650 batteriesbatteries in each tube, positive end forward, into one offorward.
[* black] Close
the battery tubestube and verify that voltage (should be around 12v for freshly charged batteries) is going to the correct pinssecure it with the correct polarityan extra 157 O-ring.
[* black] DoUsing a digital multimeter, measure the same test withvoltage across each battery tube at the other battery pack to beDB-25 connector. You should have around 12 volts dc.
[* icon_caution] Make
sure both packs are connected correctlythe polarity is correct! Refer to the DB-25 connectorwiring diagram.
[* black] The ROV is turned on and off by the topside adapter, so batteries can be placed insideleft in the ROVbattery tube safely and without it turning on. Use extra 157 o-rings to securebeing drained because the battery tube endcaps in placeOpenROV is turned "on" by plugging the mini-USB cable into the Topside Adapter. (We will do that later).
