Hello,
I am very sorry to ask this basic question. Also, sorry for bad English.
I want to make my project portable. For this I want to use Li-ion batteries in it. My project draws a max current of 4Amps at 5V ( I am using lot of LEDs). So, I wanted to use 2 2300mAh Li-ion batteries in parallel which will give me 4.6Ah. Now, I had to convert the 3.7v-4.2v from the battery into constant 5v. For this I had to use a step up buck converter. But I could not find any which could provide a max 4Amp current. The maximum I could find was 2A.
At this point I am stuck and do not know what to do. Are there any other options for converting the battery voltage into constant 5v without losing the current ? Also are there other portable power supply for projects with high current usage ?
Pololu.com has a whole range of boost (step-up), buck (step-down), and buck/boost (both) converters.
Buck seems have the highest efficiency (longest battery life), assuming you can put the batteries in series. This one might do.

Thanks for your help. I have a little idea. I was hoping you could answer my question. I am thinking to use 2 step up converters and connect one to each of the batteries separately. Then I can connect their(step up modules) outputs in parallel so that I can get a maximum of 4Amps current.
Will this work? Will their be any major problems ?
