WARNING
Do not expose the Flex System battery pack to
high-temperature locations greater than 140°F
(60°C). This includes intensive sunlight. Doing
so may cause the Flex Pack to overheat and may
result in a loss of performance and/or a shortened
life expectancy.
Cold Temperature Operation
The Volta System is capable of powering electrical
systems below freezing temperatures� However, if the
Flex Pack temperature is too low, the system does not
charge� For system operation in cold environments,
and to maintain the Flex Pack at charge-accepting
temperatures, the energy storage modules inside the
Flex Pack are equipped with internal heating pads�
The internal heating system operates automatically
when the Volta System is turned on (by the Battery
Power Pushbutton) or connected to shoreline power
in Charge Only Mode and when sufficient energy is
available from the Flex Pack�
For tips on how to operate the system in cold
temperatures, refer to the Volta Flex System User
Manual in your Owner’s Packet, and see Cold
Temperature Operating Strategies �
Ceiling and Directional Lighting
All lighting in the touring coach is LED and most
will require a replacement fixture should it go out or
malfunction� Some lighting will be operated from a
rocker switch located under the galley roof locker�
This switch will operate the water pump, accent lights,
galley lights, and the wet bath light� A rocker switch at
the rear of the lounge, operates the exterior docking
lights� A push light is located above the table, behind
the driver’s seat and adjustable, push button lights with
integrated USB ports, can be found above the rear
lounge seats� The main ceiling lights can be adjusted
using the dimmer control switch at the end of the
galley�
Entry Door Switches
The two main switch panels on the end of the galley, at
the main entry door, operate the interior ceiling lights
and exterior lighting�
NOTE
The Battery Power On/Off Pushbutton (battery
disconnect) must be ON for all switches to operate.
• The shore power connection does not meet the
charging requirements controlled by the Flex Pack
BMS� When plugged into shore power, the Flex
Pack samples incoming power for a few seconds
to ensure uniformity requirements are met� If
incoming power meets the requirements, the Volta
System turns on and begins charging the Flex
Pack� If the Volta System does not turn on, or the
Flex Pack does not begin to charge, the incoming
power is likely not meeting the Volta System
requirements� This feature protects the vehicle
from brown outs due to insufficient power.
• The selected charge rate is not appropriate for the
shore power connection� You may need to raise
or lower the Charge Rate Selection; see Inverter/
Charger Screen on page 5-16�
• If you’re using a plug-in surge protector, but you’re
experiencing problems with your Volta System not
connecting to the attached shore power, attempt
the following test: Remove the surge protector and
plug the shore cord directly into your vehicle� If
your system is now able to receive shore power, it
may be that your surge protector is not compatible
with the Volta System�
Power System Temperature Limits
The Volta System is programmed with several
operational temperature limits to protect the pack and
prolong its life� For temperature limitations see Volta
System Temperature Limits on page 9-26 and see
Volta System Temperature Ranges on page 9-27�
The Volta touchscreen displays temperature indicators,
heating pad usage, alerts, and the Flex Pack
temperature� To learn about System Indicators, see
Home Screen on page 5-15�
High Temperature Operation
The Flex Pack is designed with passive cooling� The
BMS shuts down the Flex Pack or prevents charging at
elevated temperatures to allow the Flex Pack to cool�
The Volta System charges normally and distributes
power normally up to 116°F (47°C)� At or above
116°F (47°C), the Battery Management System
(BMS) prevents charging� At or above 134°F (57°C)
the BMS shuts down the system� To protect the Flex
Pack, avoid using or storing the Flex Pack at or above
134°F (57°C)� Storage of the Flex Pack at elevated
temperatures is not recommended, as it will reduce the
lifetime and capacity of the Flex Pack�
