Product Usage Instructions

Before using the batteries, make sure to read and understand the user manual for proper usage and safety instructions.
Ensure that the terminals are torqued and bolts are not bottomed out to maximize battery longevity and safety. Failure to do so may shorten the lifespan of the batteries and void the warranty.
To check the realtime status of the battery data, download and use the Smart Bluetooth app.
The battery will provide an audible/visual alarm for 60 seconds when it reaches approximately 10% state of charge before a trip.
The LiFePO4 Smart Batteries have an IP66 rating, providing protection against high-pressure water and complete dust protection due to the machine sealing of the battery.
Ensure proper wiring as per Figure 1 for maximum number of parallel batteries and Figure 2 for maximum number of series batteries.
Keep the batteries balanced by monitoring voltage differences.
If a voltage difference appears between two sets of batteries, the balancer will move the charge from one battery to the other.
Follow the specified parameters for charging and discharging the batteries. The low voltage trip is set at 10V, and the high voltage trip is set at 14.6V.
When charging, make sure to turn off the battery via the On/Off/Reset button. The button position is up.
Ensure proper clearance (10mm) on all sides when storing or using the batteries.
For optimal storage conditions, follow the ideal storage conditions mentioned in the specifications.
Battery ventilation is required to maintain proper operation and prevent overheating.

INSTRUCTION

LiFePO4 Smart Batteries

Smart Bluetooth
Use the app to check the real-time status of the battery data

On / Off / Reset Button

Don’t have a dark-start charger handy? Just press the reset button twice to reset.
Avoid the need of an isolation switch by simply turning off at the button

Pre-trip Alarm
The battery will provide an audible/visual alarm for 60s at approximately 10% state of charge

Water / Dustproof
IP66 provide protection against high-pressure water and complete dust protection thanks to the machine sealing of the battery

Safe and Reliable

JBD BMS with full protections
Prismatic aluminium cased GFB cells with rupture vent
Vibration tested

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, either press the On/Off/Reset Button twice to reset, or 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 recommened 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 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 sea water
Do not install near heat sources
Always fuse the output positive of the battery with a fuse no greater than 2C

Before connection/disconnection, turn off the battery via the On/Off/Reset button Button position – up

Wiring Notes

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.

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.
