Hello bright minds, First off I apologize for my terrible drawing, its a gift I was never blessed with but it gets the point across. I have 3 batteries that are already in a 13S configuration (they came from Audi Q5 hybrid vehicles) they are in a nice metal enclosure and you just have your two...

Hello bright minds, I have a really dumb question, but I figured I would ask just in-case it IS an issue, I don't want to find out when its too late! I'm designing some custom enclosures for some of my battery packs. Is there any issue or safety hazard by mounting a JK BMS sideways? So say you...

The batteries: I have 3 Audi Q5 hybrid batteries that are brand new. They are Li-ion (Lithium Coltbalt Magnesium, like your 18650's) chemistry. They are 13S for 48V. I bought 3 JK BMS's: JK-BD6A17S6P I want to use these three batteries in parallel. However I am unsure the the safest and best way...

Ok so my setup currently is 2x 100watt 12V panels. I build portable 24V battery packs for use around the house to power small things. Meaning there is never batteries attached to my solar charge controller when I am not actively charging something. I got to thinking about the LOAD + = ports. I...

This cable comes from my JBD BMS system. I need to buy/create one that mates with it to complete the connection. I have no idea what this cable is called, and rather than scour the web I figured I would ask here. Looks like I need the "male version" for it to plug into. Thanks!!!

Hello brilliant minds, I have been dabbling with solar, in particular building portable 24V packs. I have two 100 watt panels in series to give me the 24v. So far so good, I'm getting the full rated amperage from the panels (just shy of 6 amps) and they fill up my diffent packs no problem. I...

Hello brilliant minds, I'm working on a prototype for providing a lot more power than what current dive lights provide for cave diving. It's clear they are using a 4S Li-ion setup that lasts about 5 hours. The price is crazy for what it is. I wanted to see if I could build my own pack with a...

Greetings bright minds from Florida, I am an electronics enthusiast for some time now, it started with micro controllers and programming simple sensors to a full blow electronics room! I have everything necessary (or mostly everything) for working and building projects. Many of the equipment is...
