What Should Battery Pack Voltage Be When Fully Charged? A

Ideal Voltage for a Fully Charged 48-Volt Battery Pack. For a 48-volt battery pack, the ideal voltage when fully charged is approximately 50.93 volts. This figure represents the

Why does current still flow with no voltage?

If the wire (or whatever you use to make the short circuit), has zero resistance, then placing a volt meter across the battery terminals will show no voltage, although a current

SOLVED: Is it Normal For BMS Voltage Reads Less Than Battery Pack

I do have the same problem. Batt voltage 54.32V, BMS output only 45V. Connecting the B- lead on top op the black balancing lead or not I do have the same result. it did not solve a thing. all

Battery Pack Sizing

There may also be a requirement to size a battery pack to have a passive thermal system, as such the heat capacity of the pack would need to be sized to suit the typical usage cycle. The

Battery problem, voltage but no current

Now it''s reading around 49 volts, but there is no current. As soon as I turn the display on it drops to zero volts and shuts off. Does anyone know what is causing this?

6 FAQs about [The battery pack only has voltage but no current]

What determines the maximum current a battery can supply?

It only determines how long the battery can supply a current for (that is, how much energy is can output over a period of time). The max current is determined by it's internal resistance. Many 4.2V lipo batteries can supply much more current than 9V batteries since they tend have lower internal resistances.

How much current can a LiPo battery supply?

The max current is determined by it's internal resistance. Many 4.2V lipo batteries can supply much more current than 9V batteries since they tend have lower internal resistances. That being said, the maximum current you can safely draw from a battery is often related to its capacity (see C ratings), but this varies battery to battery.

Why does my car battery have volts but no amps?

Another common reason behind a car battery having volts but no amps are bad contact somewhere between the rectifier and the load of the battery. You need to between the load and the anode bar to know if this is the case. If you see a drop in voltage when testing it, you can confirm that there’s a bad connection.

Do batteries go bad?

Batteries aren’t meant to last forever. Like all things, they also have a life span and they’ll go bad when the time comes. If your battery has voltage but no amps, it’s a sign that it’s reaching the end of its intended use. The battery dies due to sulfation of the plates inside or the acid or both.

How do I know if my battery is shorted out?

You are talking of a situation such as a shorted out battery. If the wire (or whatever you use to make the short circuit), has zero resistance, then placing a volt meter across the battery terminals will show no voltage, although a current flows through the wire.

Why is my 2p5s battery not working?

It sounds like you're dealing with a potential issue in one of the 5 parallel groups within your 2P5S (2 parallel, 5 series) lithium-ion battery pack. The voltage on one of the parallel groups is higher than it should be, and there is no continuity within that group.
