Do not connect batteries with different chemistries, rated capacities, nominal voltages, brands, or models in parallel or in series. This can result in potential damage to the batteries and the connected devices, and can also pose safety risks.
Avoid connecting batteries that have been purchased for more than half a year. Over time, batteries can degrade and their performance may decrease, which can affect their ability to deliver reliable power and may lead to safety hazards.
The cables between each connected battery should be of equal length to ensure that all batteries can work equally together.
You can connect up to 16 batteries in parallel.
Balance Batteries Prior to Connection
Before connecting batteries in parallel, it is important to balance them to reduce voltage differences and optimize their performance. Follow these three steps: Step 1: Charge each battery individually to its full capacity using a suitable charger.

Battery Fuse

Charge Controller

Step 2: Use a voltmeter to measure the voltage of each battery. It is best to keep the voltage difference of each battery less than 0.2V.

Step 3: Connect all the batteries in parallel and allow them to rest together for 12 to 24 hours.

It is recommended to periodically rebalance the battery voltages every six months when connecting multiple batteries as a battery system. Slight voltage differences can occur among batteries over time due to factors like battery chemistry, capacity, temperature, and usage patterns.
Parallel Connection -- Installation Steps
You can choose suitable busbars in parallel connections. Busbars help handle high currents and are typically arranged in a parallel or stacked configuration to distribute electrical power efficiently.
Note that the cable connection methods provided below are for reference purposes only, as the optimal approach may vary depending on the specific situation. It is essential to consider various factors, such as the cable size, equipment used, and environmental conditions.

Battery Cell Balancing
The battery employs bypass circuit to maintain the balance between each battery cell group. Each battery cell group is connected with a bypass resistor and a switch in parallel. During the charging process, if the highest-voltage battery cell group reaches the set balancing starting voltage and the voltage difference between the highest-voltage and the lowest-voltage battery cell group exceeds the set voltage difference, the switch connected to the highest-voltage battery cell group will be closed to shunt the charge current around the highest-voltage battery cell group through the bypass resistor until the voltage difference drops below the set value. To avoid excessive energy loss, the battery cell balancing is only performed during the charging process.

Battery Charging and Discharging Logic

The battery may be received at a partial state of charge (SOC) depending on the time between manufacturing and shipping. It is crucial to fully charge the battery before its initial use. In case the battery shuts off due to low SOC, promptly disconnect it from loads and charge it to prevent irreversible damage. Follow the instructions in this user manual for proper charging and usage to ensure optimal battery performance and longevity.

Charging Logic

The standard charging process for the battery involves charging at a constant current of 50A until the battery voltage reaches 54V, followed by charging at a constant voltage of 54V while tapering the charge current. The charging process is considered complete when the charge current is less than 2.5A (also known as tail current).

The standard charging process typically takes 1.5 hours and requires battery temperatures to be between 32°F and 131°F (0°C and 55°C) for safe charging. Leaving the battery on float will continue to balance the battery cells without damaging the battery.

Lithium batteries are compatible with various charging methods, including MPPT charge controller, AC charger, and DC-DC charger. The crucial parameter setting for these chargers is to set the charge voltage, boost voltage, or bulk voltage at 54V (±0.2V). Do not overcharge or overdischarge the battery. Do not discharge the battery at high temperatures above 140°F (60°C). Only charge the battery with a battery charger or charge controller that is compatible with lithium iron phosphate batteries. Do not exceed the maximum continuous charge current (50A) of the battery.

-- 11 --

Discharging Logic
During standard discharging, the battery is discharged at a constant current of 50A until the voltage drops to 42V. To ensure safe discharging, the battery temperature should be between -4°F (-20°C) and 131°F (60°C).
To ensure safe and optimal battery usage, it is recommended to pair the battery with discharge equipment that features a low voltage disconnect (LVD) function. Do not connect large loads to the battery when it is running low.
Do not exceed the maximum continuous discharge current (50A) of the battery.

How to Estimate the Battery SOC?

The SOC values listed below are estimated based on the resting voltage when the battery is at rest for 30 minutes, not in charging or discharging state.

SOC 100% 99% 90% 70% 40%

Open Circult Voltage 51.0V 50.3V 49.5V 49.1V 48.8V

SOC 30% 20% 14% 9% 0%

Open Circult Voltage 48.4V 48.0V 47.6V 47.2V 42.0V

The table above is for reference only because slight variations in battery voltage may occur among different batteries.

Self-heating Function

The normal operation of the self-heating function requires a stable charge current greater than 3.5A for each battery in the parallel battery bank. The self-heating function will start at optimal performance once the battery temperature drops below 32°F (0°C) and stop operating automatically once the battery temperature rises above 41°F (5°C) with a full power of 200W.

Battery Management System

The battery is equipped with a Battery Management System (BMS) that provides warnings and protections against overvoltage, undervoltage, overcurrent, short circuit, high temperature, and low temperature conditions. Refer to the table below for the triggering and recovery conditions of each warning and protection.
