Battery safe use warning

•  It is dangerous to work near lead-acid batteries. The battery generates explosive gas during operation. Do not smoke or allow sparks or flames near the battery. Provide adequate ventilation around the battery.

•  Wear eye and clothing protection devices. Avoid touching your eyes when working near the battery. Wash your hands when you are done

•  Be careful when using metal tools near the battery. Dropping a metal tool on the battery may cause a short circuit or even an explosion.

•  When using the battery, remove personal metal objects such as rings, bracelets, necklaces and watches. The battery will generate a high enough short-circuit current to melt objects such as rings, which can cause severe burns.

•  Store this product in a dry environment and a temperature of -40°C to +60°C

3. Wiring

3.1 Basic electrical connections

• Connect the negative terminal of the battery to the M10 bolt on the BATTERY MINUS side of the shunt.(Note that there should be no other connections on this side of the shunt or on the negative terminal of the battery. Any load or charger connected here will be excluded from the calculation of the battery state of charge.)

  

• Connect the negative pole of the electrical system to the M10 bolt on the SYSTEM MINUS side of the shunt. (Make sure that the negative poles of all DC loads, inverters, battery chargers, solar chargers, and other charging sources are connected "behind" the shunt.)

  

• Push the ferrule pin of the red cable with the fuse into the "Vbatt +" terminal, and then connect the M10 terminal at the other end to the positive terminal of the battery.

  

3.2 Auxiliary electrical connections

3.2.1 Monitoring voltage of a second battery

• Push the ferrule pin of the second red cable with a fuse into the "Aux" terminal, and then connect the M10 lug on the other end to the positive pole of the second battery.

  

3.2.2 Monitoring midpoint of a battery bank

The "Aux" terminal can be used to monitor the midpoint voltage of a battery bank that consists of multiple batteries that are wired in series or series/parallel to create a 24 or 48V battery bank.

• Push the ferrule pin of the second red cable with a fuse into the "Aux" terminal, and then connect the M10 lug at the other end to the positive terminal at the midpoint.

  

3.2.3 Monitoring battery temperature

• Push the two pins of the black cable into the "Vbatt+" terminal and the "Aux" terminal respectively, and then connect the M10 cable lug at the other end of the black cable to the positive terminal of the battery.

  

Download and connect TBD-smartshunt

• Download TBD-smartshunt APP and create your account

• Turn on the phone's Bluetooth

 

• Open the TBD-smartshunt APP and connect to the smartshunt device(The smartshunt device connection is shown in 3.1)

 

Make essential settings

• Set the battery capacity(Can be found on the battery)

• Set the charge voltage parameter(Conventional battery parameters are as follows:)

 

 

• Nominal battery voltageCharged voltage setting

 

Additional settings for lithium batteries

• Set the Tail current:When the current is lower than the set threshold, some lithium battery chargers will stop charging. In this case, the tail current must be set higher

• Set the Peukert exponent at 1.05:At high discharge rates, the performance of lithium batteries is much better than that of lead-acid batteries. Unless the battery supplier advises otherwise, set the Peukert index to 1.05

• Set the charge efficiency at 99%：The charging efficiency of lithium batteries is much higher than that of lead-acid batteries. We recommend setting the charging efficiency to 99%.

• Set the discharge floor:discharge floor is used for "remaining time" calculation, and the default setting for lead-acid batteries is 50%. However, lithium batteries can usually discharge more than 50% deep. The discharge limit can be set to a value between 10% and 20%, unless the battery supplier recommends otherwise.
