My lipos have arrived, pre crimped JSTs should be here on Saturday.
I have 0 experience doing literally anything with batteries so I’m hoping to take it slow and ask people to check my work at each step.
I’m going to ping a couple battery builders that have been patient enough to help me in the past @BenjaminF @Pecos @jack.luis
My goal is to setup a BMS to charge my lipo pack, preferably without soldering anything live. The pack consists of 2 cheapo turnigy 6s, 10AH lipo batteries in series. As well as a 12s 20A LLT BMS.
Here’s what I’m currently working with:
BMS underneath the battery. Battery weight supported by more foam. (Planning to add even more foam to keep the bottom flat and support every edge of the lipo pack)
I did my best to route the BMS wires without any overlap or potential for rubbing but I have some concerns here:
The wires coming out of the lipo and into the balance harness are varying lengths that I couldn’t find a way to get them to lay completely flat, is this something to be worried about and spend more time on? I plan to place another piece of foam along the front end where all the wires come out from the lipo+BMS but I’m unsure if that’s enough protection for the wires.
I attempted a bridge with kapton tape where the BMS wires interfere with the lipo balance wires, the bridge I attempted is about 2mm too narrow to cover all of the balance wires.
Should I undo all of this and start over or am I on the right track?
Edit: It’s also probably worth asking if there’s any risk to my over-usage of foam, I have plenty of unused space in the enclosure this is going in but I’m not sure if I’m missing something.
