preface

Previously, after the battery transaction, we introduced the 18650 wide temperature range battery cell produced by Uteli, which has played a good role in the actual test. This time, we continue to introduce another Uteli ULN18650C2 battery cell. Compared with C1, it has not only increased its capacity to 2500mAh, but also increased its charging capacity to 6A. The following section will introduce Uteli ULN18650C2 in detail Appearance and specification information of the cell.

Specification introduction

The basic information can be learned from the specification. The rated capacity of this ULN18650C2 cell 2500mAh@0.2C The nominal voltage is 3.6V, the internal resistance is ≤ 20m Ω, the standard charging current is 1250mA (0.5C), the maximum continuous charging current is 5000mA (2C), the standard discharge current is 500mA (0.2C), the maximum continuous discharge current is 30000mA (12C, stop discharging when the cell temperature is ≥ 75 ℃), and the charge discharge cut-off voltage is 4.2V/2.5V.

Uteli ULN18650C2 cell

As usual, let's take a look at the appearance of this cell first.

Uteli ULN18650C2 electric core is designed as a cylinder and adopts the color of purple electric core sheath film, which can be adjusted according to the requirements to meet the diversified needs of customers.

Uteli ULN18650C2 cell has code printing on the other side:

"ULN18650C2/2500mAh" and "+", "-" positive and negative pole identification;
