I''m using LTC4015 to charge a 2 cell 7.4V Li-ion battery. When the Input power (12V DC) is connected I am able to read the charge current and is approximately correct, but when I turn on

Zero Current vs. No Voltage It''s crucial to distinguish between zero current and zero voltage. While they can sometimes occur together, they are distinct concepts. Zero current implies no net flow of charge,

To make a zero current calibration disconnect the loads and charger from the BMV so no current is able to flow through the BMV''s shunt but leave the battery connected to the shunt.

Voltmeters draw some extra current, whereas ammeters reduce current flow. Null measurements balance voltages so that there is no current flowing through the

It sort of makes sense if you simplify that in practice any voltage divided by infinity results in zero current. However, it also means that infinite

When the circuit is open, it is assumed that there is an electric field between the two poles of the power supply, such as the positive and negative poles of the battery.

Seeing “0.0A” on your battery tester can be confusing, but it''s important to understand what this reading actually represents. Here''s a breakdown of the key meanings: The “0.0A” reading

Voltage is a measure of potential. You don''t need a flowing current for it to exist. Every charged battery, for example has a voltage which can be measured
