Wire Sizing Recommendations

Please see our recommendations for cable sizing below. WARNING! Incorrectly sizing your cables can result in damaged equipment and fire hazards. For more information, please see AS/NZS 3008.1:2017, or consult with an expert.

DC WIRE SIZING| 40A| 60A| 80A| 100A| 120A| 140A +
---|---|---|---|---|---|---
Wire cross section area (mm)| 10| 16| 25| 25| 35| 50
Wire AWG| 8| 6| 4| 4| 2| 1

The above recommendation is based on cable lengths of 0-1.8m. If cable is longer than this, go to next AWG size for every 1.8m of added length.
Warnings!
Review this manual thoroughly before attempting installation.
Failure to follow these safety guidelines can result in property damage, personal injury, or worse.

• If damaged upon arrival, please contact vendor for product support.
• Beware of any nearby electrical equipment that may interfere with installing this device.
• If using solar panels to charge the battery, ensure they are isolated, or covered, before connecting to the battery.
• If connecting to a DC/DC charger to charge the battery, ensure that the charger is disconnected or isolated from the house / starter battery prior to connecting it.
• Do not expose to heat, high voltage and direct sunlight.
• Do not short circuit the positive and negative terminals.
• Do not store battery along with metal and other conductive materials.
• Do not disassemble the battery.
• Do not knock, throw or impact the battery.
• Do not throw the battery into water.
• Do notinstall in under bonnet applications.
• Do notinstall in an engine starting application.

Charging Specific Advice

• In order to maximise safety, it is recommended to not charge when the site is unattended.
• When charging, keep the battery in a well-ventilated, dry, free of inflammable and explosive materials, and out of reach of children.
• Always use a battery charger with a lithium profile that does not exceed the charging specifications of the battery (see page 3).
• If you are unsure about which charger to use, please contact Amptron and consider our charger range designed for the batteries.
• Charger must not have an equalisation setting enabled. If this can be disabled then it needs to be turned off.
• When the battery leaves the factory, there is only around 30% capacity in the battery due to freight regulations, please charge the battery before use.

Discharge Specific Advice

• If battery cuts out on low voltage, disconnect load and charge battery before reconnecting the load. Depending on charger brand and model, you may need to apply secondary source of 12V-14.6V to the terminals to reset the BMS.
• A low voltage cut off device is strongly recommended if your inverter / loads do not have a low voltage cut off. Set to the voltage as shown on page 2 of this manual.
• If the battery goes below the over-discharge protection voltage (as indicated on page 3) or the over-discharge protection is activated, charge battery within 15 days.

Storage Advice

• Battery should be charged every 6 months.
• Ideally, prior to storage, charge the battery to 70% SOC.
• Ideal storage temperature is 20°C – 35°C.
• Do not leave battery in low state of charge for long periods of time.
• If battery shows signs of deformation, heat or emits smell,immediately discontinue use.

Parallel Battery Connection

2 Batteries NOTE:
ALL wires MUST be of equal length between all connections to ensure equal resistance.

For detailed instructions on connecting multiple batteries in parallel, please see our white-paper on the topic via the support section of our website.

1. Ensure all batteries to be in the parallel configuration have been fully charged individually by the same charger.
2. Ensure OCV of each battery is within <0.2V of each other.
3. After charging, set aside and allow to rest for 2-3 hours.
4. Utilising wires of circumference large enough to carry required current, connect the batteries in the above configuration.
5. Ensure all connecting cables are of the same length.
6. Be careful not to reverse connect the positive and negative.
7. Ensure correct charge voltage and current is utilised for configuration.
8. It is prohibited to series a paralleled configuration.
9. 0nce in parallel configuration, ensure a full charge is completed a minimum of every 3 months.
10. Once in parallel, the ‘system’ must be charged and discharged as if it were a single battery.

Series Battery Connection

Maximum 4 Batteries

For detailed instructions on connecting multiple batteries in series, please see our white-paper on the topic via the support section of our website.

1. Up to four batteries can be connected in series for higher voltage applications. Alternatively select a higher voltage battery which Amptron has available.

2. Ensure all batteries in the series configuration have been fully charged individually by matched chargers.

3. Ensure OCV of each battery is less than <0.2V of each other.

4. After charging, set aside and allow to rest for 2-3 hours.

5. Utilising wires of circumference large enough to carry required current, connect the batteries in the above configuration. Ensure all connecting cables are of the same length.

6. Be careful not to reverse connect the positive and negative.

7. Ensure correct charge voltage and current is utilised for configuration:
   a) Two batteries in series: 28.4V to 29.2V, recommended 28.6V
   b) Three batteries in series: 42.6V to 43.8V, recommended 42.9V
   c ) Four batteries in series: 56.8V to 58.4V, recommended 57.2V

8. 0nce in series configuration, ensure a full charge is completed a minimum of every 3 months.

9. Once in series configuration, the ‘system’ must be charged and discharged as if it were a single battery.

10. Consider additional balancers to maintain the individual voltage levels of the batteries. Please get in touch with us for recommended options.
