Product Description:
Matching resistance estimation method: Estimate the resistance value according to Ohm’s law = battery voltage divided by the expected discharge current; the resistance power selection is more than twice the battery voltage multiplied by the expected discharge current. It should be noted that the full battery voltage is relatively high. Ensure that the current cannot exceed 3.0A at full voltage!
For example. if a 12V battery needs to be tested with a 2A current. the resistance needs to be 6. the power is 50W. and the full voltage of the new 12V battery is about 13.5V. At this time. the corresponding maximum current is 13.5/6=2.25A and less than 3A. so it can be used.
In addition. if you use a bulb test. the maximum current can only be half (1.5A). because the cold resistance of the bulb is very low. and the starting impulse current is very large. If it is selected too large. it may directly burn the circuit.
Note:
Due to the different monitor and light effect. the actual color of the item might be slightly different from the color showed on the pictures. Thank you!
Please allow 1-2cm measuring deviation due to manual measurement.
