Keeps battery cables free from the E-POD housing and sharp
Connect all negative conductors! A floating negative causes
system faults!
A (system) voltage higher than 60 V causes irreparable da-
mage to the installation!
4.2 MCVB boosted charge function
Using the MCVB boosted charge function, the 48 Volt E-POD motor
can be used in an (existing) 24 V onboard network.
By connecting a 24 Volt battery bank to the MCVB boosted charge
connection, the 48 Volt, E-POD, battery bank is charged. An addition-
al charging facility is not required. See page 60 for the connection
diagram.

4.3 Batteries
The battery voltage should be 48 V nominal, with an operating range
between ≥44 V and ≤59 V. With an absolute maximum of 60 V.

The integrated motor controller limits the output as from 44 V and
stops at 40 V. This prevents excessive battery discharge.
Starter batteries are not suitable for an electric propulsion system.
Instead, semi-traction or traction batteries should be used.
VETUS can supply various maintenance-free batteries. For example
type AGM (Absorbed Glass Mat), DeepCycle or lithium 4-cell LiFePO4
are suitable for electric propulsion.
Balance the voltage of batteries connected in series. Check
individual battery blocks and make sure the voltage between
them is equal.
4.4 Battery capacity
The following points play an important role in determining the bat-
tery capacity:
- Boat characteristics (length of waterline, weight, hull shape)
- Sailing style
- Desired range
- Battery type
Table 'Power consumption indication displacement vessel' gives an
indication of the power consumption (energy consumption) of a
displacement vessel at different lengths and speeds. The power con-
sumption can then be used to calculate the sailing time. See example
below:
1. Determining battery capacity
For a boat with a length of 6 meters and a desired sailing speed of
8.8 km/h (4.7 knots) an indicative power input of 2.1 kW applies.
The desired sailing time is set at a minimum of 6 hours, continuous
sailing. This results in a required battery capacity of 2.1 x 6 = 12.6
kWh.
2. Determine battery pack
A battery pack of eight AGM batteries, maximum deep discharge
of 70%, C20 value 220 Ah, 12 V series parallel (4 x 12 V and 2 x 220
Ah) switched to a 48 V battery pack gives a usable battery capacity
of ((220 x 2) x (4 x12) x 70%) = 14.8 kWh.
3. Sailing time calculation (indication)
Based on the energy consumption of 2.1 kW, this gives a sailing
time of (14.8 / 2.1) more than 7 hours.
