Product Usage Instructions

Smart Bluetooth Features

Use the dedicated app to check the real-time status of the battery data conveniently.

On / Off Button Functionality

Avoid the need for an isolation switch by simply turning off the battery using the On/Off button. To turn off the battery, press the button in the downward position.

Pre-trip Alarm

The battery will provide an audible/visual alarm for 60 seconds at approximately 10% state of charge to alert you before a potential trip or power loss.

Water / Dustproof Feature (IP66)

The battery offers protection against high-pressure water and complete dust protection thanks to the machine sealing of the battery. Ensure the battery is securely sealed to maintain its IP66 rating.

Notes & Limitations – Warning

To maximize the longevity and safety of your lithium batteries, ensure you follow the specified parameters provided in the manual. Make sure terminals are torqued correctly, and bolts are not bottomed out to prevent any issues that could shorten the lifespan of the battery and void your warranty.

Notes & Limitations

The State of Charge monitor cannot read current below ~1A and can drift out of several weeks of no use. Complete a full charge cycle to re-calibrate
After a trip, connect to a suitable power supply or charger to restart the BMS.
After long periods of no use, or if continuously fast charging, the cells may get out of balance. The active balancer will correct this issue, to allow the balancer time to work, trickle/slow charge the battery to 14.2-14.4V and allow to hold that voltage until balanced.
Charge at least once every 3 months
If the battery trips on low voltage, and is left unattended for several weeks, the cells will continue to drop voltage and the battery may become unrecoverable – the battery must be charged within 72 hours after a low voltage trip.
To extend the service life, it is recommended to use the battery between 10 and 90%State of Charge.
Over-current trips will automatically reset after 30s.

Warning

To maximise the longevity and safety of your new lithium batteries, please ensure you follow and stay within the specified parameters. Ensure terminals are torqued and bolts are not bottomed out. Failure to do so could result in shortened lifespan and void your warranty.

Risk of Fire / Explosion

Do not short-circuit the battery or allow excess dust/moisture between terminals
Always check polarity before powering equipment on
Do not expose to direct sunlight or seawater
Do not install near heat sources
Always fuse the output positive of the battery with a fuse no greater than 1.5C
Before connection/disconnection, turn off the battery via the On/Off button Button position – down

Wiring Notes

Parallel Wiring

It is essential that all loads and chargers from the batteries evenly distribute current through the batteries, otherwise, the batteries will not wear evenly, and excessive differences may cause a battery to fail under heavy loads, such as a large inverter loading one battery most. If using an inverter or charger greater than a single battery is rated for, it is recommended that a third battery is installed, reducing the risk of a cascading failure mode.

Series Wiring

NEVER wire ANY loads from the 12V, 24V or 36V terminals, if other voltages are required, you must use a converter, i.e. a 48/36, 48/24 or 48/12 converter across the string of batteries.
Battery balancers serve two purposes:

Keep batteries balanced: Each two sets of batteries will be monitored and if a voltage difference appears, the balancer will move the charge from one battery to the other
Alarm if out of balance: If the voltage difference is too great, battery balancers will make an audible alarm to allow you to intervene before damage to the batteries occurs.

FAQ

Q: How should I wire the batteries for parallel or series connection?

A: For parallel connection, wire up to four batteries of the same model following Figure 1 in the manual. For series connection, wire up to four batteries of the same model following Figure 2.

Q: What is the ideal storage condition for the battery?

A: The ideal storage conditions for the battery include maintaining a temperature range within the specified operating temperatures and ensuring proper ventilation around the battery with a 10mm clearance on all sides.
