Accumulator box
• Aluminium accumulator box is highly resistant to
seawater for direct water cooling; encased in wa-
tertight shell constructed of fibreglass-reinforced
high-grade epoxy composite materials; can with-
stand pressures of up to 12 bar.
• Integrated microprocessor-controlled accumula-
tor management system for controlled charging /
discharging and easy operation
• Accumulator Change System (SEABOB CAYAGO
VX2 and SEABOB CAYAGO F7 models):
replaceable accumulator box
ACS makes it possible to change the accumulator
box. High-current contacts equipped with a spe-
cial seal system are used to establish the connec-
tion to the motor‘s electronic system.
Accumulators / power
SEABOB RAVEJET:
3 HP using 8 High-Energy Lithium-Ion accumula-
tor cells; approx. 1.2 kW/h; 32 V; 40 Ah
SEABOB JET 4.12:
4 HP using 12 High-Energy Lithium-Ion accumu-
lator cells; approx. 1.8 kW/h; 48 V; 40 Ah
SEABOB CAYAGO VX2:
5 HP using 12 High-Energy Lithium-Ion accumu-
lator cells; approx. 1.8 kW/h; 48 V; 40 Ah
SEABOB CAYAGO F7:
7 HP using 14 High-Energy Lithium-Ion accumu-
lator cells; approx. 2.1 kW/h; 56 V; 40 Ah
• No memory effect; long life, high performance
and high energy density
• Weight: only 1.07 kg per High-Energy Lithium-
Ion accumulator cell
• Temperature range for transport / storage:
-40 to +60 °C / -40 to +140 °F
• Recommended storage temperature:
+10 to +25 °C / +50 to +77 °F
• Operating temperature range:
-10 to +45 °C / +14 to +113 °F
Threshold values for Li-Ion accumulator cells moni-
tored by the accumulator management system
• 2.5 V: minimum cell voltage for charging (Falling
below this limit results in irreparable total dis-
charge: Charging is no longer possible!)
• 4.0 V: maximum charging voltage (charging is
stopped)
• 2.7 V: minimum discharging voltage under load
(motor stops)
• 3.0 V: minimum discharging voltage without load
(motor stops)
• 40 °C / 104 °F: charging temperature warning
(temperature display and accumulator symbol
flashing)
• 45 °C / 113 °F: maximum charging temperature
(charging is stopped)
• 55 °C / 131 °F: discharging temperature warning
(power limited to 30 %)
• 60 °C / 140 °F: maximum discharging tempera-
ture (motor stops)
• 140 A: maximum permissible momentary dis-
charging current (motor stops)
• 30 A: maximum charging current
Charging time
• SEABOB RAVEJET (8 accumulator cells):
approx. 6-8 hours
• SEABOB JET 4.12 (12 accumulator cells):
approx. 8-10 hours
• SEABOB CAYAGO VX2 (12 accumulator cells):
approx. 8-10 hours
• SEABOB CAYAGO F7 (14 accumulator cells):
approx. 10-12 hours
Using the optionally available quick charger reduces the
charging time to only approx. 90-110 minutes (charg-
ing time may be longer if mains voltage is under 230 V).
