3.3 Parallel Connections

INVICTA 48V GOLF CART allows up to 10 batteries to be used in parallel. Before parallel connection of batteries, use a multimeter to test the voltage at both ends of the positive and negative electrodes of the batteries, and ensure that the voltage difference between batteries does not exceed 2V. If the voltage difference between batteries exceeds 2V, each battery shall be fully charged separately and then used in parallel.

1. Precautions for parallel connection

A. The parallel battery pack must have the parallel function; The parallel connected battery packs must be products of the same model and part number.
B. Ensure the length of all parallel wires is consistent;
C. We suggest using 0.5C for charging, that is, charging current=battery rated capacity * 0.5C
D. When the battery packs are used in parallel, the open circuit voltage of each group of batteries must be highly consistent. It is recommended that the voltage difference between battery packs be:
Voltage difference 2000mV (@ 0%~95% SOC)
When the voltage difference is less than 1500mV (@ 96%~100% SOC), the battery pack will be charged and discharged as a whole after being connected in parallel. If one of the batteries needs to be replaced, it is recommended that all battery packs be replaced at the same time

Two 51.2V batteries rated at 30Ah connected in parallel

System Voltage: 51.2V
System Capacity: 30Ah + 30Ah = 60Ah

! Do not use the battery in series, which may permanently damage battery.

! Do not output positive and negative poles on the same battery, which may damage the battery.

3.4 Connection mode of battery communication port

1.CAN
The battery includes a Controller Area Network (CAN) bus communication interface. Two round M8 DIN connectors are located on the top of the battery to connect one battery to the other using CAN bus cables in a simple daisy chain format.

The CAN bus function is not required for normal battery operation. Automatic operation and protection of battery; It does not require any CAN bus communication or external devices (such as external controllers) or other batteries connected to the CAN bus to work. Keep the two black covers installed on the two M12 connectors to protect them from the environment when not in use.

On-site service can retrieve the battery use history and view the status through the can bus interface for diagnostic assistance.

1. Communication wiring diagram

Each group of batteries is equipped with a special communication line, which is connected by CAN busthis ensures the battery can communicate with the load or charger for more efficient use of the battery. This alsocan allow a service assistant to better understand the battery failure. If you have more questions about the CAN bus, please contact Invicta’s engineers for technical support.

4. Charging requirements

We recommend using an Invicta Lithium Charger that meets the charging requirements below for maximum performance and lifespan of the INVICTA series battery.

Discharge: -20~65℃

4.1 Charging with an AC-DC Battery Charger

Check the AC-DC battery charger you intend to use has a dedicated lithium charge setting that meets the above charging requirements. A lot of battery chargers are designed for charging lead-acid batteries only and may not have a suitable charge setting for lithium. If unsure always contact an expert for advice.

4.2 Charging with Solar

Check the solar regulator you intend to use has a dedicated lithium charge setting that meets the above charging requirements. A solar regulator without a lithium charge setting may be used to charge the INVICTA series battery. However, it must be set to charge no higher than 58.4V and then MUST be switched off once the INVICTA series battery is fully charged. DO NOT leave a solar regulator switched on without a suitable lithium charge setting once the battery is fully charged.

4.3 Charging with an Alternator via a DC-DC Charger

Check the DC-DC Charger you intend to use has a dedicated lithium charge setting that meets the above charging requirements. A DC-DC charger without a lithium charge setting may be used to charge the INVICTA series battery. However, it must be set to charge no higher than 58.4V and then MUST be switched off once the INVICTA series battery is fully charged. DO NOT leave a DC-DC charger switched on without a suitable lithium charge setting once the battery is fully charged.

4.4 Recommended charging voltage

The recommended charging voltage is set between 55.2V and 57.6V. It is strongly recommended an Invicta Lithium Charger is used to charge the battery.

5. Battery Monitoring (wired/wireless)

To monitor your battery information there are two options available which connect to the CAN communication ports.

1. Invicta digital CAN monitor (wired)
The Invicta digital monitor gauge can be connected to a CAN communication port on one of your batteries via a wired connection. The gauge can then be installed in a suitable location which is easily visible to the user. Ensure the CAN bus resistor is installed on the battery.
