The charger output is approximately 3A, which equates to a 0.3C charge rate on the Genesis 600
and a 0.15C charge rate on the Genesis 1200. This means that during the bulk charge period (first
90% of capacity), the 600 batteries will increase about 30% of the total capacity per hour up to
approximately 90% and the 1200 batteries will increase about 15% per hour, up to approximately
90%. During the last 10% of the charge, the current decreases as it approaches full charge and the
final 10% of charge takes approximately 1.5 and 3.0 hours to finish, respectively. As an example
for the Genesis 600, if during a dive, you used 50% of the battery capacity and then recharged it
for one hour during your surface interval, the battery capacity would be at approximately 80% for
the next dive.

Battery Reset Instructions
The Battery Management System (BMS) in the Genesis DPV batteries can go into “sleep” mode,
when the nose plug that enables the motor is accidentally left installed for days or weeks or the
scooter is stored for long periods (months) without use.
The proper operation of the batteries
can be identified easiest by ensuring that the green LEDs on the charger both turn red when the
batteries begin charging.
If one or both LEDs remain green for more than 60 seconds after
connecting the charger, it is an indication that one or both of the batteries may be in “sleep” mode.
The following instructions detail how to reset the BMS to “wake” the battery up. If a battery goes
into sleep mode frequently or not for one of the reasons stated above, contact the factory.
First, it is recommended that you check the voltage of each battery with a quality Digital Voltage
Meter (DVM). Low quality meters may not read the voltage correctly when a battery is shut off.
Fully charged voltage will be 33.2 – 33.6VDC. The shutdown voltage is approximately 24.5VDC. A
voltage below 20.0VDC should be returned to the factory for an evaluation of the cells and a low
current recovery charge.
To reset the BMS:
1. Remove the propeller from the tail. The magnets on the propeller coupling will be used to
activate the reed switch in the battery.
