Have the part at 27.3. ordered and on 20.4. since it is provided from Singapure came as no surprise. On the supply equal to 5 parts lists have therefore only 1 chosen, thought one goes 4 are not OK For the price you will not take any risks. Unfortunately, the display is not very accurate. At 8 volts it shows 0.2V to too little, at 12.7 V, there are already 0.5 V less. One should examine the characteristics. To check the battery level in the winter, it is quite useful in the determined deviations. Maybe I should have ordered 5 pieces and the most accurate of verwenden.Daher 4 stars.
