1.3 Product Properties
1. When connected to ACC power in the fuse box, it can be used for approximately 33 hours (based on power consumption of less than 3Wh) and can be charged in approximately 70 minutes with fast charging (7A charging).
2. It makes possible to install yourself easily using the cigar-lighter socket power cable provided, and save the installation cost.
3. When using the provided Cigar-lighter socket power cable, it automatically detects the Cigar-lighter socket connection and charges only 5A even if the charging currents is set to HIGH.
4. A micro controller unit (MCU) is built in to control the current, voltage and voltage balance of the battery, and the battery protection circuit module is built in for secondary protection to prevent the over-charge, over-discharge and over-current.
5. The output is automatically switched by the Micro Controller (MCU). This system gives to charge and output simultaneously with vehicle's engine start.
6. When the internal temperature of the battery exceeds 70°C, the battery will automatically stop charging to prevent from problems such as overheating, and when the internal temperature of the battery drops to 60°C it will begins charging. Even if charging is stopped, the output remains normal.
7. When the operating switch is set to OFF, the battery’s self-discharging period is more than 1 year because of the leaked current of the battery is cut-off.
8.The battery will be automatically cut off the current when the reverse voltage input or external short-circuit of the product's connectors occur.
9. The cycle life is improved more three times than the general Li-ion battery because of The lithium- phosphate iron(LiFePO4) battery is used, and we guarantee at least 1,500 cycles.
10. Compact design makes possible to install in confined spaces such as vehicle seat below.

2.0 Installation
※ Please set to the power-off before installation.

Do not install the product in an enclosed space, but install it in a place with good ventilation.
2.1 Cigar-lighter Socket Connection
- When connecting the product using the cigar lighter socket Input cable (5A).
- Connect the Input terminal of the battery and the cigar -lighter socket in the vehicle when using the cigar- lighter
plug power cable provided.


2.2 Fuse-Box Connection
1. When connecting the product using the Fuse-box ACC Input cable (7A).


2.3 Fuse Box

1) With the product’s power switch in the OFF position, connect the Input(charging) cable for the fuse box and output cable to the product’s cable connectors.
2) Open your vehicle’s fuse box, check the fuse standard, and select the correct fuse holder between the included fuse holders.
The fuse box location in the vehicle may vary depending on the manufacturer and model of your vehicle. For more information, refer to your vehicle’s manual.
Inside the fuse box, there's two types of power available, permanent power (BATT) and ACC contact. Since our Cellink battery is charged only when the ACC is on, you must connect only to ACC contact. If you connect to BATT contact with permanent power, the car battery will be drained or cause some error on the dashboard.
2.4 Fuse Connection

1) Insert the input cable into the sleeve at the end of the fuse holder cable, and then secure it by squeezing on the sleeve securely using appropriate tools, such as pliers.
2) Preferably, look for spare ACC contact fuse socket in the fuse box and insert the fuse tap with the included 20A fuse.
3) If you cannot find any spare ACC contact fuse socket, you can look for any existing fuse rated 10A or less with ACC contact. After removing the fuse from the socket, insert it to the fuse tap and plug the fuse tap cable back to the socket.

Before connecting the GND-O-ring cable and the Fuse-Holder cable, be sure to cut the main cable to the required length and connect it. If the main cable is long and the remaining amount is tied up, It can cause the cable heating problem from the tied part.
2.5 Fuse Tap

Insure that the fuse tap is plugged with the correct orientation with INPUT pin to the power source of the socket inside the fuse box.
Fuse supplied with the Cellink B8 is rated 20A, please do not change with other ratings.
1. Do not use mini fuse and mini fuse tap holder.
If using the existing mini fuse in the vehicle change it to small fuse type




2.6 Ground Connection

1) Find a bolt fixed on the vehicle’s and connect the ground (GND) cable to the bolt.
If the vehicle’s bolt is coated, remove the coating before connecting the ground (GND) cable. The power may not be supplied correctly due to the coating.

2.7 Proper Connection
1) Make sure that the product is connected properly.
2) Fix the product using the provided Velcro tape on the car floor such as under the car seat.
3) Turn on the switch and check that the LEDs operate properly (Refer to the LED Display table).
3.0 How to add capacity to CELLINK B8
3.1 Adding 1 unit of NEO7+ Extended to Cellink B8
