Looking at new bulk charging option for 18650

Hey Folks,

Found this interesting thing on ebay. Apparently you can link multiple casings together (series) and has built-in protection circuit...

I'm new to Li-Ion balance charge thing and was curious about these. I'm not looking for something super efficient. After all, I'm working with recycled laptop batteries.

I wouldn't trust the pcm on that thing but if you only had a bulk charger this is definitely the way to go.

Yeah, not too concerned about that. I get the batteries free. I wish they had a 12s. Looks like I'll need to do 3 x 4s to get my 48v. I may just buy one for testing and see how well it functions.
