DIY battery setup help Answered
Hi, I'm a first time DIY-er and would like to build a useful, long lasting battery pack for my *new* laptop (late summer). I'm 17, and this would be a perfect project for me to finish in the next few months. I'll be working with my dad and asking my physics teacher, who seems very all-knowing, for advice. My teacher understands electricity and batteries better than anyone else locally and is leading our STEM team, of which I am a member and need this experience. Keep in mind that I'm not just doing this to have a (much needed) battery pack for my laptop.
I got most of my information from here and will most likely be purchasing new batteries.
As far as the housing of the components, I have a hard plastic, 10+ year old lightly used blue lego container in the shape of a kid-sized briefcase.
Old blue lego carrying case, 11” x 7.5”(9 including curved front) x 3.5”
Battery holders: (x4)
PCB: (protected voltage is higher, balance charger required)
Wire terminals (for organization)
Balance charge cords:
I heard about these being inefficient, so I'm not sure about it.
Please inform me if there are any other parts that I'll need or if I've left out any information.
Also Inform me if everything I'll need for a lithium battery pack is on this list.
P.S. The case was chosen based on the fact that it will fit in my backpack with my books and looks much less alarming and more like a DIY battery than a black box or briefcase. especially with the fuel gauge and plugged in laptop.
