12V 100Ah Lithium Battery with Bluetooth

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.

You have three main options for charging your Dyness 12V100Ah battery:

• Solar Panels:
  With 400W solar panels and about 4.5 hours of effective sunshine per day, you can fully charge the battery in one sunny day.
  If using solar panels ≥400W, keep in mind that charging time can vary depending on sunlight duration and intensity. It may take longer than one day to fully charge.
• Generator/Alternator:
  For DC Output Generators/Alternators: You'll need a DC-to-DC charger to connect the battery.
  For AC Output Generators/Alternators: Use a suitable battery charger between the generator and the battery, following our recommendations.
  Important: The recommended charging voltage is 14.2V - 14.6V.
  Charging Current: 20A (0.2C): Full charge in approximately 5 hours. 50A (0.5C): Charges to about 97% capacity in roughly 2 hours.
• LiFePO4 Battery Chargers:
  Use a 14.6V LiFePO4 charger for optimal charging.
  Important: The recommended charging voltage is 14.2V - 14.6V.
  Charging Current: 20A (0.2C): Full charge in approximately 5 hours. 50A (0.5C): Charges to about 97% capacity in roughly 2 hours.

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.

Please follow these steps:

1. Make sure the battery is powered on and its voltage is at least 9V.
2. Tap the Bluetooth icon in the lower‑left corner of the app (labelled “Bluetooth Connection”).
3. The app will automatically scan for nearby devices. When the battery image appears, tap it to connect.

Once connected, you will see real‑time data such as voltage, current, power, capacity, and SOC (State of Charge).
