5.4 ELECTROPUMP BATTERY REQUIREMENTS :
When choosing the type of batteries needed for your thruster’s battery bank, keep in mind
that it is the CCA (Cold Cranking Amps) capacity that is the most important and not the Ah
(Amp-hour) capacity. This is because thrusters draw high currents, but only for very short
periods of time (maximum 3 min.)
Max Power would recommend using Exide, Maxxima 900 type batteries, which have an
800CCA and 50Ah capacity.

If the dedicated batteries are charged by the alternator, the reference of the charge must be
taken after the diode-splitting block (if in doubt, consult a marine electrician).
If the batteries or cables are inferior to those recommended, the VIP will not reach its
potential thrust. The greater the batteries and cables size, the better the thrust.
Do not ground the VIP.
5.5 BATTERY ISOLATOR:
A manual battery isolator, of the correct size, should be installed in the positive supply cable,
as close as possible to the thruster battery bank and should be easily accessible and clearly
marked.
An electrical battery isolator, as supplied by Max Power, may also be installed in the positive
supply cable, as close as possible to the thruster battery bank, in order to benefit from all
automatic safety features of the electronic control system.
