Using Multiple Batteries
Do not connect batteries in series.

Connecting Batteries in Parallel

Must connect the batteries in parallel when the batteries are fully charged, and the voltage difference must not exceed 2V.
When batteries are connected in parallel, the battery’s CAN-IN port must be connected to a remote switch or a communication terminator (purchased separately)

Connecting two or more batteries in parallel can will expand their capacity. E-Series Batteries support up to 16 batteries of the same type in parallel. Use battery bridging cables and E battery communication cables (purchased separately) to connect the batteries. Use the E battery communication cable to connect the CAN-OUT port of the 1# battery (refer to figure 2-5) and the CAN- IN port of the 2# battery and so on. Please refer to the figure below.

Connecting Parallel Batteries to the Machine

When the parallel batteries are connected to the ePropulsion outboard motor, it needs to connect the outboard motor to 1# battery with the communication cable (refer to figure 2-6). And the outboard motor can only be connected with 1# battery.
When connected in parallel, the CAN-IN port must be connected to a remote switch or a communication terminator.

Refer to Section 2.2.1 to connect the 1# battery to the machine. The figure below is the connection between the parallel batteries and ePropulsion outboard motor.

$EPROPULSION-E-Series-Lithium-Iron-Phosphate-Battery-fig- $8$$

The maximum continuous discharging current of the battery is 70A (E60)/150A (E163). Only the machine with load current less than this value can be connected.

Transportation and Storage

Transportation

Check and ensure the package is intact without any damage.
Avoid violent vibration, strike or squeeze during transport. Get adequate damping protection measures before transport.
Do not expose the battery to the sun or rain during transport.
Check applicable local, national or international laws and regulations before transport.

The below figure displays how to pack the battery with ePropulsion original packing material. For long-distance transport, it’s recommended to apply ePropulsion original package to pack the outboard before delivery.

Storage

When the battery is not in use, make sure that the battery’s connectors are covered well with the waterproof caps.
Disconnect all connections to the battery and check that all connectors are clean.
Before storage, make sure the battery level is around 45%~50%, and stored at an ambient temperature of 15°C ~ 25°C, relative humidity not more than 75%, clean, dry and ventilated place, to avoid contact with corrosive contact, away from fire and heat sources.
Protect against moisture, dust, water, shock and heat.
Every 3 months of storage, the battery should be recharged with an appropriate ePropulsion charger.

Disposal and environment
All products bearing this symbol are waste electrical and electronic equipment (WEEE as in directive 2012/19/EU) which should not be mixed with unsorted household waste. Instead, you should protect human health and the environment by handing over your waste equipment to a designated collection point for the recycling of waste electrical and electronic equipment, appointed by the government or local authorities. Correct disposal and recycling will help prevent potential negative consequences to the environment and human health. Please contact the installer or local authorities for more information about the location as well as terms and conditions of such collection points.

Routine Maintenance

Various factors like operation environment (such as temperature, humidity, dust, etc.), aging and wear of internal components, will increase the possibilities of battery failure. In order to avoid this, keep your battery in optimal operating state, and eventually extend the service lifespan of the battery. Therefore, routine maintenance is very important.

Before long-term storage, please disconnect the communication cable and the power cable between batteries and machines.
Before the first time use or reuse after long-term storage, charge the battery to its full capacity in order to achieve the best performance. Only use ePropulsion charger designed for E-Series Battery to charge the battery. Other chargers may lead to reduced battery capacity, premature battery failure, fire or explosion. Avoid over-charging, which may cause fire or explosion.
Use the battery in moderate temperature to avoid negative effects of extreme temperature posed on battery lifespan and useful cycles.
If a fault occurs, deal with the problem in a timely manner to avoid any further damage. If necessary, consult the ePropulsion authorized dealer for repair or parts replacement.
During storage, strictly follow the instructions in Section 4.2 Storage. Pay special attention to the residual charge and check the battery state in a regular manner.
Use a clean & dry towel to keep the battery surface away from oil, dirt and water. Avoid touching metal contacts. All the contacts need to be kept clean for best performance. When carrying batteries around, do not touch the contacts with metal objects such as keys or tools to avoid short circuit, battery damage, and potential fire or explosion.
To improve functionality and prolong lifespan of the battery, avoid direct sunshine or radiation exposure. Meanwhile, avoid liquid, dust or dirt entering the battery.
Do not leave the battery at a low state of charge.
It is advised to check the battery state of charge on a regular basis.
Clean all electrical contacts with electrical contacts cleaner, e.g. WD40, every two months, and clean immediately once there is rusty show up or splashed with sea water. And for long-term storage, please use conductive gel to protect electrical pins.
