DIY 18650 Battery Box 30 Cell 25V 42V 60A PCB Charging Circuit Shell for Solar Generator Power Supply

Item Description: This is a battery protection component without the cell core. Meant for the repair and assembly of battery packs, this item is strictly for users experienced with battery handling and pack construction. Key Features: 1. Overheating protection during charging/discharging and low temperature charge protection. 2. External adjustment for thermal settings. 3. Overcharge protection logic. 4. Overdischarge protection logic. 5. Three levels of overcurrent protection. 6. Adjust delay for the first and second overcurrent stages externally. 7. Battery disconnect safeguard. 8. NTC resistor disconnection safeguard. 9. Includes short circuit safety. 10. Fits Mak charger systems. User Note: If there's no voltage output after combining with the battery pack, use a designated charger to activate. For persisting problems, contact technical assistance. Safe handling and assembly: 1. Double-check polarities and connections when soldering battery leads/sampling—errors may cause irreversible circuit board damage, requiring tests before reuse. 2. BMS should not directly rest on cell surfaces; anchor assembly firmly to avoid potential harm. 3. Ground all electronic soldering devices, use electrostatic protection to avoid static/electric damage to the PCB. 4. Caution: Do not touch board components with wires or heated tools to prevent burns or shorting. 5. Maintain proper anti-moisture, waterproof, and anti-static handling at all times.
