Supoort Series And Parallel

1. General information This specification defines the performance of the GUANYU-FF-062 lithium-ion rechargeable battery produced by Shenzhen Guanyu New Energy Technology Co., Ltd., and describes the type, performance, technical characteristics, warnings and precautions of the battery pack. . The battery pack supports Bluetooth communication. Using Android and IOS APP, you can read battery status and information. Especially due to the openness of the Android system, different smart phone manufacturers will have their own different Bluetooth hardware versions and custom Android system functions. Therefore, due to compatibility issues, the application may not work properly on some smartphones (using Android). The customer needs to confirm whether the phone is compatible with the application.

4. Product Performance

NO. Items Criteria Testing method
4.1 Rated Capacity 300Ah Rest for 1 hour after fully charged, then discharge with 0.33C current until the battery reaches the discharge cutoff voltage. Repeat above process for three times, if the discharge time is not less than 120 minutes, you can stop and define the Discharging current*time value (Ah) as battery capacity.
4.2 Minimum Capacity 290Ah
4.3 Internal resistance ≤25mΩ 50% battery SOC state frequency of 1 KHZ ac resistance tester

Cycle life


≥2000cycle Discharge with the current of 0.33C until it can’t discharge, and then rest it for 1h. Charge the battery following CC(0.33C)/CV(14.6V) mode to full capacity, and then rest it for 1h. Repeat above process until full charged capacity is no more than 80% of normal value. Accumulated times is defined as cycle life.

Discharge Temperature


-20℃ ≥70% At 25±5℃ discharge the battery with the current of 0.33C to the cut-off voltage and record charge capacity. Store the battery at various temperatures for 2h and discharge the battery with 0.33C to the cut-off voltage.
-0℃ ≥80%
25℃ ≥100%
55℃ ≥95%
4.7 Charge Retention ability



Charge the battery to full capacity and store it for 28days, and then discharge it with 0.33C to the cut-off voltage.
