36V 55Ah Marine Trolling Motor Lithium Battery

They offer 4000 cycles at 100% Depth of Discharge (DOD), 6000 cycles at 80% DOD, and up to 15,000 cycles

To connect in series or parallel, batteries should meet the below conditions:
identical batteries with the same battery capacity (Ah) and BMS (A);
from the same brand (as lithium battery from different brands has their special BMS);
purchased in near time (within one month).

Because of the different BMS, it's not recommended to connect these 2 types of battery in series or parallel.

For versatile system configurations, you can connect multiple Dyness 12V 100Ah Trolling Motor LiFePO4 batteries.
You can expand your battery bank's voltage and capacity by connecting identical batteries:
Series: Connect up to four batteries in series to create a higher voltage system (e.g., 24V, 36V, or 48V).
Parallel: Connect up to four batteries in parallel to increase the total capacity (Ah) to 400Ah.
Series-Parallel: Build a larger bank of up to 16 batteries in a 4S4P configuration (4 in series and 4 in parallel) for maximum power and capacity.

⚠️ Critical Connection Requirements
To ensure safety, performance, and longevity, all batteries in a connected bank must meet these conditions:
Identical Model: Use the exact same battery model (e.g., Dyness 12V 100Ah Trolling Motor Bluetooth) with the same capacity (Ah) and BMS rating (A).
Same Brand: Never mix batteries from different brands. Each brand uses a unique Battery Management System (BMS) that is not compatible with others.
Recent Purchase: The batteries should be purchased close together, ideally within one month, to ensure they are from the same manufacturing batch for balanced performance.
Voltage Matched: Before connecting, ensure all batteries are fully charged and their voltages are balanced to within 0.1V of each other. This prevents large inrush currents that can damage the batteries.

As you are storing the battery for a long period of time, here are some suggestions for long-term storage for your reference.
1.Temperature: A temperature between 10°C to 35°C / 50°F to 95°F is ideal for long-term storage. Store in a fireproof container and away from children.
2. Capacity: For a longer-lasting product, it is best to store your battery at a 50% charge level and recharge every three months if it is not going to be used for a long time.
