charging

So basically i found an old CTV and thought why I shouldn't just put a Wii in it. There was enough space to fit an untrimmed board which made things way easier. I want to use 8 batteries in 4s2p but I need a BMS. I've been thinking using this one but im not sure. Here the questions: 1. Can I...

starting work on a portable Wii, last time I was active modding in Wii was a decade ago, 4.2U. Never dabbled in portablizing or board trims, so this is all really cool exciting stuff to me, but I'm not sure on best practices for power control. I have an OLD wii (-01 motherboard, I still have...

I thought about creating my own 3s Li-ion balancing/charging circuit to place on my recent projects pcb. But after some research, I havent found any solid leads on how to approach something like this. For comparison, if you search for "DIY audio amp circuit", you get truckloads of great designs...

So I hooked up the famous Red Board™ to my batteries, double checked the connections, and plugged it in. Problem is, one charger didn't charge them at all and the second one caused the red light to flicker quickly and the voltage to drop relatively quickly. The AC adapters have the same ratings...

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...

Hello, I have an internal 4 cell 18650 battery pack in my portable, I was wondering the best way to unify them so that they are all charged and regulated from one charge input, and then have a cumulative battery output voltage. I was looking at this board here but I am unsure which points to...

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 imagine you have yourself a portable Wii with a built in GC controller. BUT, you retain the stock cable for the controller, and it plugs into the console. (This would basically be if you used a GC keyboard controller shell for the whole system). In this manner, you could plug your portable...
