What is the charging voltage for a 4.2 V battery
For the charger to be within specifications the charge voltage must be between 4.15 volt and 4.25 volt. Values below 4.15 volt will increase the lifetime of the battery and charge it to a lower capacity.
What does 4.2 V battery mean
For example, almost all lithium polymer batteries are 3.7V or 4.2V batteries. What this means is that the maximum voltage of the cell is 4.2v and that the "nominal" (average) voltage is 3.7V. As the battery is used, the voltage will drop lower and lower until the minimum which is around 3.0V.
Can I charge a 3.7 V battery at 4.2 V
Generally, a 3.7v lithium battery needs a "protection board" for over-charging&discharging. The battery without a protection board can only be charged with 4.2V voltage, because the ideal full charge voltage of a lithium battery is 4.2v, once the voltage exceeds 4.2v, the battery may be damaged.
Can I charge 4.2 V battery with 5V
Yes you can, but the concern is what happens when the voltage exceeds 4.2 volts. In the case of lread acid or NiMH types nothing except a slight outgassing or mild heating, in the case of a li ion ,it could result in a fire. . This type of battery cannot handle extremes and needs to be electronically protected.
Can I charge 18650 to 4.2 V
18650 lithium-ion batteries are charged up to 4.2V and down to between 2V and 3V depending on the cell's specification for cut-off voltage. To be safe, never discharge lower than 3.0V unless you know your cell's specification.
What is the maximum charging voltage for A 4 volt battery
Ideally, you will use a regulated bench power supply to charge your batt properly. limit max V to: 4.84V (±3%) (Note: As the batt charges, V will increase to this level–if the batt is good) limit max current to: 0.8575A (Note: As the batt charges, current will decrease from this level–if the batt is good)

What is the maximum charging voltage for a 4 volt battery
Ideally, you will use a regulated bench power supply to charge your batt properly. limit max V to: 4.84V (±3%) (Note: As the batt charges, V will increase to this level–if the batt is good) limit max current to: 0.8575A (Note: As the batt charges, current will decrease from this level–if the batt is good)
Is 18650 3.7 V or 4.2 V
Not all 18650 batteries have the same voltage – they range from 2.5V to 4.2V. However, when you compare your 18650 battery 4.2V vs 3.7V, the the former can provide longer durations. When charging your 3.7V lithium ion battery, do not use a charger that has more than 4.2V.
What voltage is too low for 18650
18650 lithium-ion batteries are charged up to 4.2V and down to between 2V and 3V depending on the cell's specification for cut-off voltage. To be safe, never discharge lower than 3.0V unless you know your cell's specification.
What is the charging voltage of 4.8 V battery
So on a 4 cell 4.8v Ni-CD battery charging with a voltage of 6v, that is 0 3v per cell above nominal voltage. The charger should stop charging when the voltage reaches 4.8v on a 4 cell Ni-CD battery (1.2v per cell).
What is the voltage of charged 3.7 V battery
4.2V
The maximum voltage your 3.7V lithium ion battery can have is 4.2V, also known as the maximum safe voltage/charge cut-off Voltage.
Does 4 12V batteries make 48v
Note that 4 x 12v batteries are wired in a series to achieve 48v, there can be 2 or more 48v series of 4, wired in parallel to each other. 6v batteries are typically golf cart batteries, which are excellent for solar or DC powered air conditioner applications.
What is the maximum voltage for a 4S battery
16.8v
For example a 4s battery, which contains 4 lipo cells in series, would have a maximum charge of 4.2v x 4, or 16.8v. A 6s battery would have a maximum charged voltage of 25.2v. And the more voltage you have, the faster an electric motor will spin.
Is 4.2 V the same as 3.7 V
3.7V is the rated voltage of the lithium battery, and its upper limit voltage for charging is 4.2V, also known as the limit voltage. In the case of the same size and capacity, a battery with nominal voltage of 3.7V is the same as a battery with a limit voltage of 4.2V, so the former can be used instead of the latter.
At what voltage is a 3.6 V battery dead
Lithium-ion

|---|---|---|
| 3.6V | 2.8–3.0V | 4.2V |
| 3.7V | 2.8–3.0V | 4.2V |
| 3.8V | 2.8–3.0V | 4.35V |
| 3.85V | 2.8–3.0V | 4.4V |
What is the lowest voltage for 3.7 V battery
Your 3.7V lithium ion battery can be considered dead (completely discharged) at a voltage of 3.4V. Your battery mustn't discharge beyond 2.75V (minimum safe voltage), as it could reduce its life.
What is the charging voltage of a 3.8 V battery
4.35V
LiPo Battery 3.8V Series
The high voltage 3.8V lipo battery has more than 10%-15% capacity than the general 3.6V & 3.7 lipo battery. The fully charged voltage is up to 4.35V, and the cut-off voltage is 3.00V.
Can 5v charge 3.7 V
Charging a 3.7v battery with a 5v charger. Here's everything about using a 5 V charger to charge a 3.7 V cell phone battery being safe to use: It's not safe to charge a 3.7 V cell phone battery with a 5 V charger for both the equipment and personal safety.
Can we charge 3.7 V battery with a 4.8 V charger
Lithium ion are often quoted as 3.6 or 3.7v “nominal” or average. Either way, the 4.8v charger is unsuitable. It might overheat, or eventually overcharge the battery, which will cause it to overheat, and possibly worse.
What voltage range is a 48V battery
For example, if you have a 48v battery, 48 volts is the 'nominal' voltage or middle of the range of voltages for that battery. When you charge a 48v battery it actually charges to 54.6 volts and when it is empty it will be somewhere around 40-41 volts.
