Bluetooth range is strongly dependent on the environment and how the Li-ion battery is positioned. Metal parts such as battery boxes, covers and cabling can affect the Bluetooth range and can lead to reduced range. The mentioned range only applies to an “open field situation”, and can be less or more depending on the situation. 3.6.5.

4.4.2. Connecting power cables with cable lugs 1. Remove the automotive power terminals. (Figure 9) 2. Connect the load or charger to the X2 (+) terminal of the Li-ion battery. (Figure 10) Use the included M8 bolt, spring washer and plain washer to connect the Li-ion battery cable. 3. Connect the X1 (-) terminal of the Li-ion battery. (Figure 10) Use the included M8 bolt, spring washer and plain washer to connect the Li-ion battery cable. 4. Ensure both contacts are tightened to 20Nm. 5.

The Li-ion battery has a M6 thread on both terminals that is intended to supply power to small consumers. Below it is described and depicted how to connect small consumers. This is not the accessory power; that one is FASTON 1 underneath the lid (see figure 6, paragraph 3.6.2).
4.5. Communication and FASTON connections All connections, except for the connection terminals, can be made in one central place under the protective lid. This protective lid is mounted and held in place using self-retaining clips, the lid can be easily removed with light force and replaced in the same way. The specific connections and assignment are indicated on the inside of the lid. The connections can be made using standard 4.75mm wide automotive FASTON crimp terminals.
4.6. Connecting to the CAN interface 4.6.1. Connecting the data cables The wired communication interface must be used in a bus network topology (Table 17). Do not use a ring- or a star topology. The wired communication interface specifications restrict the Bus length/Bus speed. Bus length (L) Max. stub length (S) Accumulated stub length 250 m 11 m 55m Table 16.

reflections on the line. The value of this resistor should be +/- 120 ohms. More information on termination resistors can be found in CiA document 303_1 V1.8.0, section 5. 4.7. Connecting to the LIN interface The Li-ion battery includes a LIN interface (Local Interconnect Network). The LIN interface can be used to connect to a LIN master which are often present in (recreational) vehicles or caravans.
4.7.1. CI-BUS protocol To support easy integration within the RV/caravanning industry the LIN bus protocol is configurable. One of the protocols which can be selected is the CI-BUS protocol. When enabled, the LIN bus provides all information necessary for the system using the CI-BUS protocol. For more information about the CI-BUS visit the CIVD website (https://www.civd.de/ en/artikel/ci-bus-board-management-system/). 4.7.2.
4.8. Connecting a charger to the Li-ion battery ! Warning! Ensure you have completed all the previous steps described in chapter 4 before connecting the Li-ion battery to the charger. Battery charger + - Plus (+) X2 X1 Load Minus (-) Figure 17. Connecting a charger to the Li-ion battery 4.9. Connecting Li-ion batteries in parallel ! Caution! Before connecting 2 or more Li-ion batteries in parallel, the Li-ion batteries must be charged to 100% SoC. The max.
OK: Equally divided battery current. All batteries contribute equally to the current into the load. NOT OK: Current not equally divided. Batteries closest to load will have the highest contribution to the current into the load. Whereas batteries further away from load will have lesser current contribution. Wear and tear will be higher on the Li-ion battery close to the load. Never connect the setup like this! 4.10. Disconnecting the Li-ion battery 1.
! booster) is indispensable. Caution! To charge the Li-ion battery, use a charger which follow Super B’s charging profile (see charging manual which can be found on the Super B website). 1. Connect the charger to the Li-ion battery as described in paragraph 4.8. 2. Charge the Li-ion battery immediately in case of an under-voltage shutdown or if the state of charge drops below 20% to preserve the lifespan of the Li-ion battery. 5.2.1.
Caution! The FASTON GND; GND FASTON is fused at a lower rate than the heater consumes. Do not connect the GND for the heaters at the FASTON GND connection. When an external source is connected, it is automatically used to heat the Li-ion battery cells. The BMS detects whether power is available at the FASTON Heater power input. If the user wants to use external power only, heating from terminal power must be disabled (method 1) or method 2 must be used.
Method 3: Keep at charge temperature source independent This method keeps the cell temperature above 0°C from external power supply energy or the Li-ion battery energy itself. If an external source is available, it will be used for heating. If the external source is not present, energy from the Li-ion battery will be used to keep at 0°C. In that case it will keep it at 0°C until the SoC drops below a configurable level. If that level is reached the heaters will stop to prevent draining the Li-ion battery.
SoC shutdown has two settings: • Switch off level (error level) (by default ON at 10% SoC) • Warning level (by default ON at 15% SoC) The warnings are shown on the LEDs on top of the Li-ion battery and also communicated to all the communication channels so that it can be shown on the Be in Charge App / Software or the Display.
5.6. Be In Charge Software and App Super B provides a Be In Charge Software tool which can be used to read out the internal BMS system. The software uses a CAN to USB converter to connect to the communication interface. The software is capable of reading out the actual status like battery / cell voltages and temperature but also statistical information. The Be In Charge software can also be used to update the installed firmware of the Li-ion battery.

Battery history recording The complete Li-ion battery history and statistics can be downloaded using the Be In Charge Software. 5.6.3. Reading the battery’s State of Charge (SoC) The Li-ion battery is equipped with an analogue SoC output, this output provides a voltage between 0 and 10 Volts which reflects the 0-100% state of charge value.
6.2. Inspection 1. Inspect for loose and/or damaged wiring and contacts, cracks, deformations, leakage or damage of any other kind. If damage to the Li-ion battery is found, it must be replaced. Do not attempt to charge or use a damaged Li-ion battery. Do not touch the liquid from a ruptured Li-ion battery. 2. Routinely check the Li-ion battery’s SoC. Lithium Iron Phosphate batteries continue to slowly self-discharge (<3% per month) when not in use or stored. 3.
9. Disposal and recycling Always discharge the Li-ion battery before disposal. Use electrical tape or other approved covering over the Li-ion battery connection points to prevent short circuits. Li-ion battery recycling is encouraged. Dispose of the Li-ion battery in accordance with local, state and federal laws and regulations. 10. Troubleshooting Problem Possible situation Solution Li-ion battery is in operation mode Green LED is lit or flashing.

CAN connections does not seem to work stable or does not work at all. CAN connection errors Make sure to use the right CAN cables. make sure all connections are made and all connectors are screwed down. Make sure to always use two terminator resistors in the CAN bus at both ends of the bus. Make sure that the cables are in good condition and connectors are not broken or damaged. Table 21.
