4.1 প্যাকিং এবং পরিদর্শন

Carefully remove the battery from its packaging. Inspect the battery for any signs of physical damage, such as cracks, dents, or swelling. If any damage is observed, do not proceed with installation and contact customer support immediately.

4.2 প্রাথমিক চার্জ

It is recommended to fully charge the battery before its first use to ensure optimal performance and calibration of the Battery Management System (BMS).

4.3 সংযোগ

Ensure all connections are secure and properly tightened to prevent resistance and potential hazards.

• Connect the positive (+) terminal of the battery to the positive (+) terminal of your load/charger.
• Connect the negative (-) terminal of the battery to the negative (-) terminal of your load/charger.

For Multiple Batteries:

• সমান্তরাল সংযোগ: To increase total capacity (Ampere-hours) while maintaining the nominal voltage (12.8V), connect positive terminals together and negative terminals together.
• সিরিজ সংযোগ: To increase total voltage, connect the positive terminal of one battery to the negative terminal of the next battery.

The Dyness 12V 100Ah battery supports connecting up to 16 modules (4 in series x 4 in parallel) for a maximum system of 51.2V 400Ah (20,480 Wh).
