2. Інформація про безпеку
Always read and understand all safety instructions before installing or operating the battery. Failure to follow these instructions may result in serious injury, property damage, or voiding of the warranty.
Загальні заходи безпеки:
- Не розбирайте, не модифікуйте та не проколюйте акумулятор.
- Тримайте акумулятор подалі від вогню, джерел тепла та прямих сонячних променів.
- Не занурюйте акумулятор у воду чи інші рідини.
- Use only compatible chargers specifically designed for LiFePO4 batteries.
- Забезпечте належну вентиляцію під час заряджання та розряджання.
- Використовуйте відповідні засоби індивідуального захисту (ЗІЗ), такі як рукавички та захист для очей, під час роботи з акумулятором.
- Уникайте короткого замикання клем акумулятора.
- Зберігати в недоступному для дітей місці.
Захист від низької температури:
The Dyness LiFePO4 battery includes a low-temperature charging protection feature. Charging will automatically disconnect when the battery's temperature drops below 32°F (0°C) and will resume at 41°F (5°C). Discharging will automatically cut off power at -4°F (-20°C) to protect the battery from damage.

4. Налаштування
Середовище встановлення:
- Install the battery in a dry, well-ventilated area, away from direct sunlight and heat sources.
- Ensure the installation surface is stable and can support the battery's weight.
Connecting Batteries (Series and Parallel):
The Dyness 12V 100Ah LiFePO4 battery can be connected in series (up to 4 batteries for 48V systems) and in parallel (up to 4 batteries for increased capacity) to meet various energy requirements. Always ensure all batteries are of the same type, capacity, and state of charge before connecting them.
- Паралельне підключення: Connect positive terminals to positive terminals and negative terminals to negative terminals. This increases the total capacity (Ah) while maintaining the voltage (12 В).
- Послідовне підключення: Підключіть позитивний вивід одного акумулятора до негативного виводу наступного. Це збільшить загальний об'єм.tage (V) while maintaining the capacity (Ah).

Термінальне підключення:
The battery uses M8 terminals. Ensure all connections are secure and properly torqued to prevent loose connections and potential arcing.
5. Інструкція з експлуатації
Зарядка:
For optimal battery health and fastest/safest charging, it is highly recommended to use a LiFePO4-specific charger. Recharging at a 0.2C rate (20A for a 100Ah battery) is recommended for optimal battery longevity.
- Connect the charger's positive lead to the battery's positive terminal and the negative lead to the battery's negative terminal.
- Ensure the charger settings are appropriate for a 12.8V LiFePO4 battery.
- Monitor the charging process, especially for the first few charges.
Розрядка:
The battery's built-in BMS protects against over-discharging. However, it is good practice to avoid consistently discharging the battery to its absolute minimum to maximize its lifespan.
- Connect your load to the battery terminals, ensuring correct polarity.
- Do not exceed the maximum continuous discharge current specified in the specifications.
6. Технічне обслуговування
Регулярні перевірки:
- Periodically inspect the battery terminals for corrosion or loose connections. Clean as necessary.
- Ensure the battery is kept clean and free of dust and debris.
- Check the battery casing for any signs of damage or swelling. If damage is observed, discontinue use and contact support.
Зберігання:
- If storing the battery for an extended period, ensure it is charged to approximately 50% State of Charge (SOC).
- Зберігайте акумулятор у прохолодному, сухому місці, подалі від прямих сонячних променів та екстремальних температур.
- Під час тривалого зберігання заряджайте акумулятор кожні 3-6 місяців, щоб запобігти глибокому розряду.
7. Вирішення проблем
The built-in 100A BMS provides extensive protection, which may cause the battery to shut down under certain conditions. Refer to the table below for common issues and their solutions.
| проблема | Можлива причина | Рішення |
|---|---|---|
| Акумулятор не заряджається | Over-discharge protection activated, low-temperature charging protection, charger issue, loose connection. | Check battery temperature (must be above 0°C/32°F). Verify charger functionality and connections. If deeply discharged, a specialized charger might be needed to reactivate. |
| Акумулятор не розряджається (немає вихідної потужності) | Over-discharge protection, over-current protection, short circuit protection, low-temperature discharging protection. | Reduce load. Check for short circuits in the system. Ensure battery temperature is above -20°C/-4°F. Disconnect load for a few minutes to allow BMS to reset. |
| Перегрів батареї | Excessive load, poor ventilation, high ambient temperature. | Reduce load. Ensure adequate ventilation around the battery. Move battery to a cooler environment if possible. The BMS will activate over-temperature protection. |
| Незвичайні запахи або набряк | Internal cell damage. | Immediately disconnect the battery from all loads and chargers. Do not attempt to use or repair. Contact Dyness customer support immediately. |
