How much voltage/current is "dangerous"?
A shock from a circuit protected with an ELCB / GFI device will be felt but will USUALLY not be fatal. A 9 V battery on the tongue almost certainly won''t kill. A 9 V battery across the chest with saline solution (or sweat) just might - probably not. A 12 V "car battery" or any high current source from a few volts up MAY kill in the very worst

Using Ultracapacitors for Voltage Stabilization | DigiKey
Ultracapacitors, which can economically supply high currents and deliver large amounts of power in time frames as long as a few minutes, can thus act as a supplemental power supply to stabilize the network voltage during the start of a machine. Therefore, the main power supply will be minimally affected.

BQ25606: Failure to provide enough current
If this is significant, changing your resistors to higher charge current setting may force the charger into early CV/Termination, while not actually charging the battery fully. Try this test without a real battery first; i.e. using a power supply with the ability to sink current, or a constant voltage E-Load.

It sounds like the question is whether there is some sort of hysteresis in a lithium (ion) battery such that a load this too resistive will not draw current. In general the answer is no, there is no minimum supply current needed to stabilize the output of a battery. (Switching power supplies do have a minimum current.) Experimentally, a

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 can I maintain a fix voltage until my battery is almost dead?
A battery''s voltage naturally drops as it discharges. To get a stable voltage out of it, you want a voltage regulator. Voltage regulators come in two flavors, linear and switching. If you want the output voltage of the regulator to ever be higher than the battery voltage, you need a switching regulator. You''ll also get higher efficiency that

Get a quote6 FAQs about [The current is not enough to stabilize the battery]
Is there a minimum supply current needed to stabilize a battery?
In general the answer is no, there is no minimum supply current needed to stabilize the output of a battery. (Switching power supplies do have a minimum current.) Experimentally, a voltmeter across the battery terminals will have a typical input impedance of 10 MΩ, so it would draw only 0.3 µA of current at 4 V.
Why are batteries not suitable for voltage stabilization?
Moreover, batteries do not perform well in cold weather. These factors limit the acceptable battery applications for voltage stabilization. Notice that the machine start is a short process, usually lasting less than a few seconds. During this process, a large amount of power is required.
What happens if a lithium ion battery is not stable?
The symmetric pulses cause side reactions if a battery is not stable. The amount of side reactions is quantitatively extracted as a coulombic efficiency. Evaluating the stability of a lithium ion battery (LiB) typically involves the measurement of a few hundred charge and discharge cycles during the development stage before mass production.
What determines the current of a battery?
The current is a function of the difference in potential between battery voltage and alternator output voltage. The current is a result proportional to that voltage delta and the resistance of the charging circuit. The "hunger" of the battery ultimately determines the current, up to the capacity of the alternator.
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.
Why is a voltage stabilizer necessary?
Therefore, a voltage stabilizer is necessary to maintain a stable supply of voltage to the load and overcome fluctuations so that electrical equipment can be protected from over or under voltage.
