4D & 8D BATTERIES
Communication:
The battery has two RJ45 ports for communication with Volthium-compatible accessories. Both ports offer RS485 communication, so it doesn’t matter which port you choose to connect your Volthium accessory to.
Waterproofing:
The battery is fitted with black (or yellow) rubber caps which are essential
to maintain the battery’s watertight integrity.
They must be installed correctly to prevent water infiltrations.
Note that there is still a sealant on the inside (epoxy / Silicone) of the connectors to provide a safety barrier, but external protection remains essential.
If the battery is installed in a humid environment prone to condensation, or where rain is likely to reach the battery, please apply a dielectric sealant around the RJ45 ports.
If you are permanently plugging in an RJ45 cable, then fill the port completely with dielectric grease and then plug in the cable. Be generous, it has to overflow.
Dielectric grease is not harmful when injected into the RJ45 connector.
Volthium keeps Permatex dielectric grease in stock.
SKU: ACC-PMT81150
If the battery is to be used in a salty air environment, please also cover the stainless-steel switch, and apply an even more generous coat to seal the battery.
Switch:
The battery is fitted with a switch that disables discharging, while allowing charging current to enter. When the switch is depressed, the battery can be discharged and recharged for normal use. If the switch is not pressed, then the voltage on the terminals will be below 6V, and the battery cannot be discharged, but can still be charged. The self-heating system will also be functional if the switch is in the OFF position.
Heating system and use of the H+ Connector:
Batteries with yellow tops have a small connector called H+. This provides access to the manual heating system for industry professionals only. Only batteries with the self-heating function will have a functional H+ port. For batteries with the self-heating function, the automatic self-heating system is systematically implemented. It is activated when sufficient current is applied to the battery, and when the battery is below 0 degrees Celsius.
For the manual system, simply connect an energy source to the H+ terminal and close the circuit with the negative terminal, and the internal heating pads will activate. Note that the manual system is 100% manual, and no thermostat is installed. That’s why it’s reserved for experts.
Load parameter:
Please refer to the technical data sheet for charging instruc9ons.
Warning:
– Never exceed 60V on a series connection
– Do not use to start engines
– Always use a protective device when an alternator is in the electrical
circuit (DC-DC).
– Never store the battery when it is flat.
– Be sure to precharge the circuit capacitors before connecting the lithium
battery (unless the battery includes the Soft-Start feature, available on
certain Volthium products).
– Cycle batteries thoroughly at least twice a year to keep cells balanced and
healthy
