battery

Hello! Thanks to this forum I have been making great progress and I am feeling more confident in completing this seemingly impossible Gamecube Portable project! However, one question that still troubles me is the choice of battery. I am thinking of keeping everything 12V to ensure stability...

I have a bunch of 18650s from various sources. Is there a method I should use to test their health before I use them together? Any rules about matching capacity? Also, is there a BMS (like the ebay "red battery boards") that would be suited to using many cells together? I'm not really sure...

I am completely inexperienced working with batteries and making them, I want to be as cheap as possible with my Wii Portable build, and have a relatively small battery pack. If someone who knows more about this could help me out, It'd be very appreciated. What I need to know: What's the most...

I've got a question on the feasibility of taking a portable charger, say an Anker power pack, disassembling the pack to improve form factor, and using it for a power source. Is this possible? I've realized that spending $20 on a battery pack that already comes with a protection circuit might be...

So I discovered that you can buy "18650" 3.7V Li-ion cells (5800mah/per cell apparently) for really cheap here in Canada, plus they're quite small. Four of them wired in series can supply 14.8V... a good amount to give to a Wii portable, no? Wondering if any of you have done this or if it's a...

After doing my research on powering the wii, I have to decide on batteries and came across something I haven't seen yet. The cool part about the custom regulators is that you seem to be able to power it with whatever voltage you want (above 5v I believe). So that means that it's within the...

I am referring to the circuit inside of the portable and how can you add a battery life indicator to tell if the battery is charged or dead? SOLVED:

So I have 100% decided that I will be making a Wii Laptop as my first portable. I have little to no experience with electronics, but i know the things I need to know, and all thanks to you! So, I will NOT be making a laptop case for this, instead, I am mounting a screen in a wii. Even though i...
