Technical description

The advanced LiFePO4 battery offers the desired features like charging below freezing, series connected batteries as well as BLE and CANBUS connectivity. The battery is equipped with a Battery Management System (BMS) that is built in the battery housing. The battery management system is a non-power consuming, passive electronic device that protects the battery against deep discharging, overcharging, over-temperature, and ensures cellbalancing of all serial switched blocks during charging. The battery has the following features:

Communication ports
The two connectors are for inter-battery communication for parallel and series connecting batteries.

Reserve capacity
Reserve capacity of 5 % is provided to allow users to perform emergency actions with the battery even when it is completely discharged. This is accomplished by disconnecting the battery before the battery is completely discharged.

Power button
Button with LED for indicating and controlling the power mode of the battery.
This button allows transition between the following modes:

Heater
There is a heater inside the battery on the bottom side of the cells. This heater is controlled by the BMS and allows the battery to be charged at ambient temperatures as low as -20 °C. The BMS implement three modes for heater control.

Capacitor pre-charge
The pre-charge and pre-discharge circuit in the BMS allows large capacity banks to be charged prior to connecting the cells. This avoids damaging inrush currents.
Fault recovery
If the BMS disconnects the battery due to a fault, it will reset automatically when the conditions return to normal.
For low voltage disconnect, the BMS shall allow up to 10 A of current to be drawn from the battery.

Components

The 100 Ah battery has the following components:

1. Battery Connections
2. Slanted sides prevent batteries from being installed without an air gap between them for cooling
3. Integrated screw holes for easy mounting. This works well for width limited enclosures
4. Communications ports (CANBUS)
5. Power button with status LED
6. Staggered terminals allow parallel/series connections without much wire interference

The 300 Ah battery has the following components:

Easy mounting works well for width limited enclosures.

4| Communication ports (CANBUS)
5| Power button with status LED
6| Staggered terminals allow parallel/series connections without much wire interference
7| Optional brackets for easy mounting to a wall

Installation

Mounting the battery

• Mount the battery either in vertical or upright position with the screws and the mounting bracket to a wall.
• Do not mount the battery on the wall without the mounting bracket.
• Do not mount the battery on the wall with mounting bracket in horizontal position.
• A maximum of 8 batteries can be connected in parallel.
• A maximum of 4 batteries can be connected in series.

Connecting multiple batteries

WARNING! Electrocution hazard
Do not hot-swap the battery pack connection unless necessary, it will cause surge current. If the battery pack needs replacement, it is necessary to turn off all the battery packs by pressing the physical button of one battery pack until the LED lights of all the battery packs are off.
NOTICE! Damage Hazard
The embedded BMS in the battery is designed for a of maximum 4 batteries in series. Do not connect more than 4 batteries in series. Ensure that the batteries are in power OFF mode before connecting.

1. System harness
2. Inter-battery harness
3. Terminator

• To connect multiple batteries connect the batteries as shown.
• The master battery can now communicate with the secondary batteries.

Configuration
The batteries communicate with each other using the CANBUS ports to co- ordinate balancing. The master battery collects the information from the secondary batteries in the bank and relays the information on behalf of the entire bank of up to 32 batteries via BLE and CANBUS.

1. Using the Go Power! Connect app, configure the battery pack as follows:
   • Hold down the power button for 2 seconds or charge to wake up each battery pack, battery enters power ON mode and LED is solid light.
   • Fully charge each battery pack separately. Ensure the voltage difference between battery packs is within 1 V of each other.
   • Assign each battery pack ID one by one via mobile app and setting a master battery pack which communicate with UPS/application system, other battery packs are set for slave.
   • Press and hold power button for more than 15 seconds to shutdown battery pack. LED will turn off.
2. Press one of the battery buttons for 2 s or add a charger to wake up all battery packs.

Operation

• Batteries are in power off mode when unboxed. Press the power button for 3 s to turn on. If the battery doesn’t turn on, charge the battery.
• All batteries need to be configured before they can be used.
• Ensure that the battery pack terminals are correctly installed and connected to the inverter system.

Choose the power mode

1. Press button for more than 3 s and release. The battery will enter into sleep mode. The LED will flash. Power off mode should only be used for long term storage or to reset the BMS. Use the sleep mode to disable output power of batteries.
   Preventing a surge current

2. Ensure that all batteries are in power off mode.

3. Press the power button on one of the battery packs for 3 seconds to wake up all battery packs from Power Off mode.

• The LED indicator turns on.

Using the Advanced Lithium app

1. Download the Go Power Connect! app.
2. Add a device for the GP-ADV-Lithium battery.
3. Setup one master battery by pressing and then configure each individual battery.
4. Press Indicate to blink the power LED for physical reference of the current battery configured.
5. Press Setup for each individual battery to configure it.
6. Press Load System when each battery is configured. Changing the DC Instance will change all the batteries to match for the battery bank.
7. Set the battery instance configuration through the change battery instance (master/ secondary).
   • Set the battery instance to assign different instances for each battery.
   • Batteries in series must have the same series string value. Batteries wired in parallel must be different from each other.
   • There must be only one master per DC source. All other batteries on the DC source must be in secondary.
8. Press Load system to run the main functionalities.
9. Monitor the battery voltage, DC current, power, Ah remaining, time remaining, charge state, and battery temperature.

Charging

WARNING! Damage Hazard

• Do not hot-swap the battery pack connection unless necessary, it will cause surge current.
• Do not charge with higher current than recommended value. It will damage the battery electrical, mechanical and safety performance and could lead to heat generation or leakage.
• Charging current should be less than maximum charging current.
• Charging voltage should be less than 14.6 V. Charging beyond this absolute maximum voltage is strictly prohibited.
• The battery should be charged within the charging temperature range.
• Reverse charging is prohibited.
• The battery should be connected correctly and the polarity should be confirmed to be correct before wiring.
• In case the battery is connected improperly, the battery cannot be charged.
• The reverse charging may cause damage to the battery which may lead to degradation of battery performance and safety, and could cause heat generation or leakage.

Discharging

• The battery should be discharged at less than the maximum discharge current.
• High discharging current may reduce the discharging capacity significantly or cause over-heat.
• The battery should be discharged within the discharging temperature range.
• To prevent over-discharging, the battery should be charged periodically to keep about 60% charge.
• Over-discharging may cause loss of battery performance, characteristics or battery functions.
• The charger prevents the battery from discharging beyond the discharge voltage threshold.

Cleaning

• The lithium batteries are maintenance-free.
• Occasionally clean the product with a damp cloth.
