Battery currant regulation ?

I'm trying to replace this 380 mAh 3.7v battery with a much larger mAh battery, but I'm guessing I need to know or have some kind of regulator between the battery and the device.

This photo shows what I guessing is the regulator of this small battery.

Is there a way I can figure out what kind of regulation or resistance I will need on the next battery or can I just use this very same regulator (if that's what it is ? ) ?

Thank you.

If you do a search on the Net, you may find much higher mAh batteries at the same voltage.  So there  would be know reason to be concerned about changing a regulator.  Unless there's not regulator on the board in question.  Check: banggood.com and Aliexpress.com  also Amazon.com

The 380 maH is the batteries current rating, it just determines how long it will last. So, in this case, your battery can provide 380 milliamperes for one hour at the rated voltage. It could also provide 190 milliamperes for two hours, or 760 milliamperes for half an hour.

Replacing the battery with one that has a higher current rating WON'T cause your device to consume more current. The new battery will just last longer than the old one did. As long as it has the same voltage rating, 3.7 volts in your case, it will work.

However, one thing you will need to determine is how to charge it. The battery you pictured is a LiPo (Lithium Polymer) battery and they have very stringent charging requirements. I'd strongly recommend that you read up on this before you attempt to charge it.

I'll actually be doing a video and article about this soon, as I'll be using LiPo batteries for a few projects I have planned. But that will not be for a couple of months.

Thanks for responding Bill.

I should have included that the battery in the photo is a Li-po. I'm thinking I want to go with a Li-Ion bat instead.  And no matter which type of bat I chose to go with I'm still going to have to know or have the proper regulator between the bat and device am I not ? This is also why I am trying to I.D. the plug connector for size and fit. If I knew the exact connector I have on this battery it would help me in deciding on the next battery. If I have to cannibalize this bat I could but I only want to if I'm sure it's going to work correctly. And I don't want to buy or build another bat with out knowing what is the correct regulation needed  or should I be concerned ? I guessing the currant circuit board on the photo battery is a regulator.

The reason I want to upgrade to a higher mAh rated battery is to get more run or stand by time. The photo bat is from a small camera I use. But I come across this issue all the time where I have a device that I want to modify for a given application but I need more run time. Then I have to figure how to correctly charge it. I've been searching for video instructions on how to do this but no luck so far.  If you know of a or some video's that provide this info please let me know. Or if you decide to do this type of video that would be very useful since your good at through explanation. Maybe if you gave several different examples, that would be very useful.  I'm sure I'm not the only person who has this interest and needs to know all the proper considerations to be calculated for a custom up grade application.
