Safety Cautions

⚠ Do not disassemble or modify the battery housing — this may cause leakage, overheating or explosion.
⚠ Do not throw the battery into fire or water, and do not expose it to high temperature above 60°C.
⚠ Always use the matched LiFePO4 dedicated charger (CC/CV mode) — do not charge with the original lead acid GAM charger, and do not over charge or over discharge the battery.
⚠ Stop using the battery immediately if swelling, overheating or abnormal odor occurs, and keep it away from children except under adult supervision during charging.

Frequently Asked Questions

Q1: Is ENL-FP6 a direct replacement for the BL2503 lead acid GAM battery?-

A: Yes, ENL-FP6 is designed as a drop-in replacement for BL2503 lead acid GAM batteries with the same 6V output, matching size of 46*70*100mm and brass silver plated contacts. It fits children electric toy cars, electronic scales, solar lights, warning lights, searching lights and oxygen pumps directly without any modification.

Q2: What are the advantages of LiFePO4 compared with lead acid GAM batteries?+

A: ENL-FP6 delivers 1.5x the working time at only 40% of the weight of an equivalent lead acid GAM battery, and offers up to 10x the cycle life. LiFePO4 chemistry also provides lower self-discharge, stable discharge curve and much longer service life, dramatically reducing replacement frequency and total cost of ownership.

Q3: Can I charge ENL-FP6 with the original lead acid GAM charger?+

A: No. Please always use a dedicated LiFePO4 charger with CC/CV charging profile. Lead acid chargers have a different charging voltage and cut-off logic, which may cause over charge and damage the battery. If you need a matched charger, please contact our sales team.

Q4: What protection functions does the battery have?+

A: The battery is built with a comprehensive protection circuit including over current protection, over charge protection, over discharge protection, temperature sensor and reverse polarity protection, ensuring maximum safety during charging and discharging.

Q5: What is the warranty and can it be customized?+

A: We provide a 12-month full quality warranty. OEM customization including label printing, capacity and connector customization is available for bulk orders. Feel free to send an inquiry below with your requirements.
