So I just picked up my first Volt battery. I've been a Volt driver for a year now and love the car and now I wanted to tinker with the battery. I'm sure I'm not knowledgeable enough to really dive too far into it yet but it was a good price and I plan on doing my research before getting touching too much of it. I was told the car only had 10,000 miles on it but the battery had been sitting for quite some time. I dragged it home and pulled the fiberglass cover off and noticed that it's missing some of the cables and what I assume are the BMS parts that plug into the top of each module. I got the battery for 1200 dollars which seemed like a good deal but if I want to run a BMS in the future am I going to have a hard time locating those plugs? I have the 4 from the back section of the battery but not the front. I measured each 48v module at 45.5 on the nose and all the cells measured 3.801-3.803 volts. Without knowing everything there is to know I think that's in the acceptable range without being over discharged I hope. I realize I'm behind the curve to grab such a powerful battery but I've got a decent background in DC electronics but never with lithium and never anything this powerful. Should I call and complain about not getting the entire assembly or was my deal good enough that I should just be thankful for what I got?

Thanks! I have been gorging on info since picking that pack up. Safely broken down and into my workshop for further review now. As they warmed up(it was 20 degrees this morning) they showed a little higher voltage. I plan on configuring some of them(the 24 volt modules) for an electric bicycle and the others for a house battery in my RV.

Not to over simplify this whole thing as it's incredibly dangerous but the way this whole battery is built is pretty awesome. I already got it broken down into the smaller packs. Can't wait to tinker more with this! I'm already looking for my next battery! Now that batteries are becoming affordable I can't wait to build my dream electric motorcycle! A perfect dinghy for my motorhome.

I don't think I'll ever draw too much off of them in my motorhome. Just some LED lights, small water pump, a few amps for a DC refrigerator and maybe a couple other random things. I really just want to minimize the need for a generator and solar. Since I'm not worried about leaving these batteries in a partial state of charge it doesn't matter as much if they aren't replenished every day. Or at least that's my theory, if I'm wrong hopefully someone will tell me. What do you do to maintain that 80 degrees in the winter? I suppose if I built a box to store them and had an inverter running inside it might keep them warm. I would like to set up the liquid cooling/warming option but I haven't seen any good setups for that.
