5.1 ערשט נוצן
It is recommended to fully charge the battery before its first use to ensure optimal performance and calibration of the BMS.
5.2 בלועטוט מאָניטאָרינג
The battery features integrated Bluetooth for real-time monitoring via a smartphone application. Follow these steps to connect:
- Download the official WEIZE battery monitoring application from your device's app store (iOS/Android).
- מאַכן זיכער אַז בלועטאָאָטה איז ענייבאַלד אויף דיין סמאַרטפאָנע.
- Open the WEIZE app and search for available devices.
- Select your battery from the list to connect. The app will display real-time data suchs as voltage, current, state of charge (SOC), temperature, and BMS status.

5.3 BMS Reactivation
If the BMS cuts off the battery due to protection (e.g., over-discharge, low voltage), the battery will automatically reactivate after 1 second once the fault condition is removed. No external higher voltage input is required for reactivation.
6. טשאַרדזשינג ינסטרוקטיאָנס
Always use a dedicated LiFePO4 battery charger. Using chargers designed for other battery chemistries (e.g., lead-acid) can damage the battery and void the warranty.
Recommended Charging Methods:
- Method 1: Dedicated 12V 20A Lithium Charger
A 12V 20A LiFePO4 charger can fully charge the battery in approximately 5 hours.
- Method 2: Generator + 20A DC-DC Charger
Connect a generator to a 20A DC-DC charger for charging. This method also takes approximately 5 hours.
- Method 3: Solar Panel + MPPT Controller (>800W)
For solar charging, use a solar panel array with an MPPT controller capable of delivering over 800W. Charging time will vary depending on sunlight conditions, typically one sunny day for a full charge.

Figure 6.1: Visual representation of three charging methods: a dedicated 12V 20A lithium charger, a generator with a 20A DC-DC charger, and solar panels with an MPPT controller. Each method indicates an approximate charging time.
NOTE: The BMS includes low-temperature charging protection. If the battery temperature is too low, charging will be automatically suspended until the temperature rises to a safe level.
7. וישאַלט
WEIZE LiFePO4 batteries require minimal maintenance compared to lead-acid batteries.
- רעגולער דורכקוק: Periodically check battery terminals for corrosion or loose connections. Clean terminals with a wire brush if necessary.
- סטאָרידזש: If storing the battery for an extended period, ensure it is charged to approximately 50% State of Charge (SOC) and stored in a cool, dry place away from direct sunlight. Recharge every 3-6 months to prevent deep discharge.
