Battery Connection
Safe and reliable installation requires trained and certified technicians. Therefore, the purpose of this section is only to serve as a guideline as all scenarios cannot be covered.
Preparation
Before the installation and operation of the battery, it is recommended to have the following equipment or tools available:
· Proper Protective Equipment · Insulated Tool(s) · Multimeter · Battery Cable · Battery Charger / Charge Controller
Inspection
Please check for visible damage including cracks, dents, deformation, and other visible abnormalities. The top of the battery and terminal connections should be clean, free of dirt and corrosion, and dry. If any problems are detected with the battery, please contact us for assistance. Refer to the last page of the manual for contact information.
Cable Sizing
Battery cables (sold separately) should be appropriately sized to handle the expected load. Please refer to the following table for the ampacities of copper cables with different gauge sizes.

Copper Cable Gauge Size (AWG/mm) (.) (.) (.) (.) (.) (.) (.) (.) / (.) / (.) / ()

Ampacity (A)

The above values are from the NEC Table .(B) for copper cables rated at °C (°F), operating at an ambient temperature of no more than °C (°F). Lengths in excess of feet ( mm) may require heavier gauge cable to avoid excess voltage drop in undersized wiring.

Battery Terminal
The depths of the female battery terminal threads are no more than mm. Consider this when determining the proper bolt length to secure bus bars, cable lugs, and any washers that will be affixed to the terminal connection pad. If too much torque is applied to a bolt, the female threads of the battery terminal will be stripped and the damage will not be covered under warranty due to misuse of the product. Consider the mm thread depth when selecting your bolts so that they do not bottom-out. Conversely, a minimum of threads must be engaged before applying lb-ft of torque so as to not damage the threads.

Connecting Batteries in Banks

CAUTION

The batteries pack support max S or P, but in practical applications, consumers need to calculate

based on their own load situation.

The maximum voltage after series and parallel connection of battery packs should less load voltage.

The load current should be less than the recommended current of the battery pack after series and parallel connection.

It is recommended to balance the voltage before using it in series or parallel. DO NOT string batteries with different chemistries, brands, models, rated capacities, or nominal voltages in parallel.

In parallel battery banks, the cables between each battery should be of equal length to ensure that all batteries in the system can work equally together.

The built-in BMS of the battery pack only protect and balance the internal battery cells. If the battery pack is connected in series or parallel, if you want to achieve better protection and balance, you can additionally install an external BMS control.

Battery Charging
LiFePO Batteries perform a -stage charging algorithm called “Constant Current/Constant Voltage” (CC/CV). The standard LiFePO profile is .C CC charge to .V, and then, CV at .V charge until the charge current declines to <=.C. The recommended max. charging current for a Ah LiFePO battery is A (.C). A faster charge of A (C) may be used as necessary, however, regularly charging your battery this way may shorten its life and subsequently its total capacity due to the extra heat generated during this process. We do not recommend using any other types of chargers for LiFePO batteries, such as SLA and Gel chargers.
Battery Storage
Temperature
The battery can be operated at temperatures of -~°C (~°F), and a temperature between to ( to ) is ideal for long-term storage. Store in a fireproof container and away from children.
Capacity
For a longer-lasting product, it is best to store your battery at a % charge level and recharge every three months if it is not going to be used for a long time.
Troubleshooting
If any problems occur during the battery operation, please refer to the following instructions or contact us for assistance
