5.3 Charging the Battery Systems (Q-Boat 1800P)
The Q-Boat 1800P is normally equipped with three 24V 10Ah NiMH battery packs and a smaller
battery pack inside the handheld RC transmitter. It is important that the user fully charge each
battery system before deployment.
The propulsion batteries’ operating endurance between charges ranges from 30 minutes to 90
minutes, depending on operating speed and use of steering.
Once each month, the propulsion battery(s) should be fully discharged before recharging to
avoid memory problems that may be caused by repeatedly charging partially discharged
batteries.
To charge the remote control transmitter’s battery pack, refer to the transmitter manufacturer’s
instruction manual.
1.
Disconnect all shipboard connections to the batteries and remove the battery(s) from the
boat.
2.
Place the batteries in a well-ventilated area away from flammable hazards ensuring the
batteries are spaced sufficiently to allow proper airflow during charging.
3.
Ensure the 3-to-1 adapter cable has been disconnected from all three white Molex
connectors, or “discharge terminals”, as shown. (See figure 5.9)
Important:
The battery charge terminals consist of three Tamiya connectors that are tinted
greenish-yellow. These are the connectors that will be used for charging. The white Molex
connectors are used for discharge (runtime operation) only and should
never
be used to
charge the battery. Depending on the battery, one of both types of these connectors may
have identifying labels. (See figure 5.10)
4.
Connect the three charging adapters to each port on the 12V battery charger. Each adapter
is a 2-piece assembly. Ensure all adapters terminate in greenish-yellow Tamiya connectors
that match each battery’s charge terminals. (See figure 5.11)
5.
Select the desired charging rate on each port via switches on the panel. Choose either a
0.9A or 1.8A charging rate (slow and fast charge respectively). By default, the chargers ship
with a 1.8A charging rate selected.
6.
Connect the three greenish-yellow charge terminals on the battery to the three charging
adapters on the charger. (See figure 5.12)
7.
Verify that the charger’s input power requirements are compatible with your region’s line
voltage before proceeding. Connect the charger’s AC cord to the outlet and turn on the fron
power switch to begin charging. The charger indicator lights will show red during charge and
green when charging is complete. (See figure 5.13)
