Product details

The battery is charged by the specified charger. The single-cell battery charging current is <2.5a, and the charging voltage is 4.2 (+0.03)v. If the battery voltage is lower than 3.0v, the battery is charged with 0.25a current. When the battery voltage reaches 3.0v. Then, the standard current is used for charging. If the battery voltage is always lower than 3.0v, the charging is stopped. The battery pack is designed with a protective circuit board to ensure the battery is safe from misuse. The voltage is greater than 4.35 ± 0.05v overcharge protection circuit, the charging current is turned off. When the voltage is between 2.20 and 2.40v, the overdischarge protection starts, the discharge current is turned off, and the current consumption is less than 10μA.When the discharge current exceeds 5.0A, the overdischarge current protection function is activated and the discharge current is turned off. 12.2.3 The battery pack charging temperature range is -20-60 °c; the battery pack discharge temperature range is -40-70 °c; the battery pack storage temperature is -55-80 °c; the battery pack working environment humidity is less than 70%.

Product qualification

All sensors either are EX type or are intrinsically safe. Zone barriers are installed in the Unit. Using well-known brand products at home and abroad, the sensors of mud logging unit have the advantage of technical and performance indicators. At the same time, the service life is long. 6.Delivery shipping and services CNPS can ship the goods to you by Express, Air, or sea .
