2.1.4 Announcements of parallel connection before start-up
1. Install and pile the batteries correctly, and then turn the switch to ‘ON’ position, start up the
batteries. When the batteries are installed wrongly, it would lead to startup error. After starting up
the system normally, the batteries would distribute the address automatically. The main control
box at the top would judge through the data sent from the below batteries.If the data sent from
the batteries are judged to be normal, the batteries would be started up successfully, otherwise
startup would fail.
2. Shut down. When the battery is not charged or discharged, then you can shut down the battery.
The switch can be used to cut-off the circuit when the battery is powering the loads. But to protect
outer devices, we suggest to firstly shutdown the loads and stop charging/discharging and then
turn the switch to ‘Off’, and make sure that the indicators are OFF, so that the battery is shut down.

4. Management System (BMS) Function
BMS has following function: Over-charging protection, over-discharging protection, high-voltage
protection, low-voltage protection, charging over-current protection, over-temperature protection,
low-temperature protection, short-circuit protection, battery cell balance function.
5. Product exterior Requirement
Battery exterior keeps clean, and installer need to firstly clean dusts and scrap iron before
installation and power on. And installer shall keep the area clean.
6. Data Storage Requirement
The battery test data must be stored in the database. So that the data can be checked with SN
number.
7. Packing, Transportation, Storage Requirements
7.1 Product Package Packing Requirements
Battery module precharge to 60%~70% SOC or deliver according to customer requirement. The
battery remaining SOC after going on boat depends on the storage time and storage condition.
1. Battery Module meets UN38.3 Certificate Standard.
2. Especially, the package must follow Revised Special Rule of Road Cargo Transportation and
Existing Dangerous Goods Act.
7.2 Product Transportation Requirements
Battery must be prevented from strong shaking, impact, extrusion, and must be prevented from
sunlight and rain. The battery can be transported through car, train, boat, air etc. for transportation.
The battery shall be lightly moved during assembly and disassembly, and cannot be dropped, rolled
and pressed hardly.
7.3 Product Storage Requirement
Battery shall avoid exposure to corrosive matters, and shall be away from fire and heat source.
Suggestion for storage:
a)Long-time Storage (more than 3 months), battery shall be stored under 5~45℃, relative
humidity 65%, without corrosive air. Battery module shall be stored under 5~45℃, dry, clean,
with good ventilation. Battery shall be charge to 50~55% SOC. And it is suggested to do a
chemical active charging and discharging every 3 months. The maximum time interval cannot be
longer than 6 months.
Note: If the battery is not long-time stored in the correct way mentioned above, the battery life
cycle would be decreased greatly.

8. 【Regular Maintenance】Check the Battery Voltage through Monitoring. Check whether the
system voltage is normal or not. For example: Cell voltage is abnormally high/low.
8.1 SOC Check:
Use Monitoring system to check Battery System SOC status, and check the battery SOC is normal
or not.
8.2 Cable Check:
Check all the cables with eyes. Check whether there is breakage, aging, loosing.
8.3 Balance:
Long-time of not fully charged would lead to battery module unbalance. Solution: Do balance
maintenance every three months (Charge to 100% SOC). Generally speaking, this process can be
achieved automatically through communication between system and outer devices.
8.4 Output Relay Check:
When load is small (low current), control the switch of output relay, to hear the sound from the
relay, so that you will know that the relay is working normally.
8.5 History Check:
Analyze history records, check whether there is accident (warning, protection), and analyze on
the reasons.
8.6 Maintenance:
For the functions that needs maintenance during restarting, it is suggested to do maintenance
every 6 months. need recycle,
Destroyed batteries could have electrolyte leakage or generate combustible gas. If there is fire,
please call local Fire Alarm Number. If the destroyed batteriesthe recycling process shall follow
the local rules to achieve the recycle of related items.
If there is any further question, please contact us.
