4. Product Performance


NO.ItemsCriteriaTesting method
4.1Rated Capacity12Ah

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.

4.2Minimum Capacity11.4Ah
4.3Internal resistance≤80mΩ50% battery SOC state frequency of 1 KHZ ac resistance tester
4.4Short circuit protectionYesConnect the positive and negative of this battery pack through a lead with the resistance less than 5mΩ.

Cycle life

(DOD100%)

≥2000cycleDischarge 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.
