The participating Volvo Ocean 65 boats are each powered by two MLI
Ultra 24/5000 Lithium Ion batteries, giving a total battery power of 10
The batteries have a primary source of charging via two 24/150 A
Mastervolt alternators, regulated by two Alpha Pro charge regulators,
which can fully charge the Li-ion batteries in one hour. In addition, all
boats are equipped with a water-powered charging system.
Each boat is equipped with a DC distribution 500, that fuses the DC cables
and can generate an alarm over the network, when a fuse blows.
Battery monitoring is provided via the MasterShunt and the internal
shunts fitted within the batteries. These components provide critical
system data that is communicated via MasterBus and the CZone Bridge
onto the CZone Touch 5, and the displays located at the navigation
station and in the cockpit.
There is comprehensive system monitoring provided via the CZone
network, which will also emit audible and visual alarms when actions are
The CZone network also powers the navigation, communication and
hydraulic systems fitted within the vessel.
When the boats are in port, charging is provided by a Mastervolt
ChargeMaster 24/30-3. Regardless of the available mains (90-265 V,
50 or 60 Hz), the ChargeMaster can charge the batteries anywhere in
Detailed system diagnosis and troubleshooting are provided remotely
by the Mastervolt technical team, via Master Adjust, CZone Configuration
Tool and Mastervolt QS.

“As a Dutchman, I’m extra pleased to have
Mastervolt on board, a Dutch brand like
AkzoNobel. From experience on my own boat,
I know that Mastervolt is super-reliable, which
is exactly what we need in the Volvo Ocean
Race. Rather than worrying about the electrical
system we need to be able to fully focus on the
sailing itself. With Mastervolt on board, I am
sure that will be the case.”
