  You want to increase current without changing battery? And right now battery current capacity is 5 amp?

  crazy john

  yes....is it possible to do so ??
• 

  Harshad Italiya

  Battery is constant current source. 😔 seems difficult.
• 

  crazy john

  Is there any other alternative to achieve this amount ??

  Once i heard about some chip which used to amplify current have to check all spec of that. I'll try to get exact part number of that chip.

  thank you godfather .

  But if we try to harness more current than the rated from a battery, it would collapse, right? Its designed to reach only that maximum value.

  Yes we can't draw more than its rated current but we can use some chip if available which convert voltage into current.

  Like a step down transformer decreasing the voltage but stepping up the current.

  Yes exactly like that. 👍

  1. If tried to do so the mAH rating would be proprtionally reduced to half.
  2. If u stepdown the voltage to increase the current , to achieve its double capacity i.e 10 Amps., the voltage would wear down to 12 volts making it useless for the given appliance.

  Agree in this case first have to check if that lower voltage is not problematic then we can use such step down chip which gives higher current.

  I want to increase the amount of current from 5amps to 18amps.....am using 24V battery as a source . Please help me to deal with this problem .

  That mean you are using 12V battery in series to have 24V(i think).
  If you want to increase the current connect same voltage rating battery current will not matter.
  and if you don't want to connect more battery in this case the current values always depends on the load resistance,too...!!

  There is only one battery of 24V, and yes current depends on load resistance but you can't draw more than its rated capacity.

  Now this is a question that the asker of this question can answer. Whether 12 volts is ok with him. And whether he wants the battery too be used on the same appliance or what?

  I read somewhere in another section by the same user he might want to use this battery in the process in which they are generating Hydrogen.

  like a small projectwork. a full schematic circuit sdrawing would help me to explain every aspect clearly

  Is this possible with DC source? As, AC can be amplified or transformed... 😀

  We can use high speed DC switching.

  Power converetor ics can be used. I am sorry to use the word transformer

  Can't we use Transistor as a Current Amplifier?

  Transistor is practically more of a current limiter than an amplifier. In the links given by you what happens is that you are giving a minute current in the base emitter part. Whereas on the other hand you have a battery connected which is capable of giving some current , lets say 5 A (max.) . you can control it between the range 0 to 5 ampere { only in the mesh collector , emitter and the battery}. you are practically amplifying nothing but just controlling the current by a small amount of current in the base emitter junction.

  Then it seems only possibility is the transformer as it can do with it turns ratio but even though it does, the losses will be pretty high as well as the losses depend on current!
  
  However, cannot we cannot draw more current than rated though since power will always remain constant as these Voltage and current values will vary depending on P=VI.
