How to reduce the current of livestock battery voltage

These regulators have a dropout limit of 2 V (typical.) Incidentally, series regulators are the worst choice as the excess voltage has to be dissipated as heat. Perhaps you can proceed more skillfully and not regulate the voltage, …

How do you charge a battery with a current limiter?

There are two ways to provide a current-limited supply to charge a battery. a) The current limiter way. Use an active current limiter. The simplest of these, if you have the voltage headroom, is an LM317, which maintains 1.2v between its output and adjust terminals. If you connect (for instance) 12ohms between them, it will limit at 100mA.

How do I reduce my battery voltage to 6 volts?

To reduce the voltage down to 6, there's a number of possibilities, depending upon how precise the voltage needs to be. Voltage regulator (s) are the way to go here. Adjustable regulators that provide 6V at 3A are quite common, but you'll need more components to set them up. This might even cost you more than those batteries did.

Why do buck regulators have a negative current limit?

The negative current limit prevents the inductor current from reversing direction and flowing out of the load. Soft Start: It is important for buck regulators to have an internal soft-start function that ramps the output voltage in a controlled manner upon startup to limit the inrush current.

How much power does a Li-ion battery need?

Figure 1 shows a typical low-power system operating with a Li-Ion battery. The battery’s usable output varies from 3 V to 4.2V, while the ICs require 0.8 V, 1.8 V, 2.5 V, and 2.8 V. A simple way to reduce the battery voltage to a lower dc voltage is to use a low-dropout regulator (LDO).

How do I charge a LiPo battery with a resistor?

If you are actually using this to charge a lipo battery -- a resistor in between the power supply and your battery is the simplest way to do it, but it's not active current limiting. Your current will be the highest when the battery is at the lowest voltage. – Schematic created using

How much voltage does a battery need?

The battery’s usable output varies from 3 V to 4.2V, while the ICs require 0.8 V, 1.8 V, 2.5 V, and 2.8 V. A simple way to reduce the battery voltage to a lower dc voltage is to use a low-dropout regulator (LDO). Unfortunately, power not delivered to the load is lost as heat, making LDOs inefficient when V IN is much greater than V OUT.

How Much Current Is available in Series-Connected Batteries?

Connecting batteries in parallel will increase the current and keep voltage constant. Vtotal = single battery voltage (e.g. 1.5V) Itotal capacity = Summation of all batteries current capacity (e.g. 2+2+2=6A) You can use combination of connecting batteries in series or parallel to achieve your desired current capacity and voltage margin.

What is the easiest way to lower the DC output (reduce voltage)?

You are looking for a voltage regulator. Switching ones are more power efficient. The most practical solution will be a device sold as a battery eliminator or universal AC adaptor. Often they have a switch allowing you to choose an output voltage from a selection of multiples of 1.5V.

How to Reduce Voltage with Resistors

Let''s do one more example. Say if you have the same circuit above with 5V but only want 1V. If we use a 10KΩ as our R1 resistor, plugging in the values, we get R2= (V)(R1)/(VIN - V)= (1V)(10KΩ)/(5V - 1V)= 2.5KΩ. So we can use a 2.5KΩ …

A simple way to drop the voltage is …

How can I reduce voltage on a battery. | Forum for Electronics

Have you tried dropping battery voltage a few volts artificially as you switch on the tool? A few diodes in series is the obvious way to do this. Say 4 diodes rated for 10 Amperes. However this method of resistive drop wastes a few tens of Watts as heat.

Battery

Unfortunately a 12 V lead-acid battery will drop to 12.6 V very quickly unless the discharge rate is very low. At 2 A it would be below 12.6 V in minutes. It would likely use a power transistor and an op amp along with a voltage reference. If you need current limiting, additional circuitry would be required. Lynn
