Feel free to talk me out of this.
I have access to several hybrid battery packs from a customer who dismantles cars. The two I have sitting here are 300v and 5.5ah. They are made up of mutiple 6 volt sticks in series. If I took them apart to create a 12v system I end up with about 137ah right...
It has on OBD2 port? Then you're good to go. That talks to both the ECU and the TCM. Using HP tuners software and cable you can link up to it. The software is free but you have to buy the cable and pay per VIN.
Yes if that engine and trans use the normal GM computers, every single aspect of how it runs and shifts can be altered. Those engines are also very turbo friendly. Double the HP, easy.
I get it now. Nothing to prevent any number of mods though once it is sold to the customer. Some states have their DOT inspection but many don't. I won't even have to emissions test my NPR in Tennessee because it's a diesel and I can register it as an RV no problem
Should be really easy to do. Just take the paneling off and have a look at how the latch works and go from there. A cable hooked up to pull on the latch mechanism usually works really well.
I don't mind really but this could make another good thread all on it's own. Mine is currently around 3* but haven't had it up to much speed. What little I've driven up and down the block has felt great though.
I drove it a few weeks ago. Ran well and was not slow. Not fast either but.... Anyway I had to move it out today to get a customers 69 Mustang fastback on the chassis table so I took it out back and did a little flex test. Not too bad for now. It will improve with more load on the back and some...
See I got myself mixed up. I know the stuff about absorption rate going down as soc goes up. I just forgot.
So to avoid having to idle for hours on end at times, seems like I need more solar than 200W and most likely as you said, the dcdc charger isn't needed. I'll just do a relay setup or even...
Thanks for this. Definitely learning here and it's not helping me to randomly google info either. It's all over the place....
Just checked the idle voltage and it's 14.2. I will do the half drained test like mentioned above and post back about that.
I see what you're saying now. It would take much longer to charge the bank with the dcdc charger than without. So when I am doing the math, I should use half my Ah right as I wouldn't want to drain the batteries past 50%. Doing that with a 450ah bank discharged 50% I get a charge time of 2.4hrs...
Great info and thanks for your help everyone. To add missing info... I’m planning on space for at least 4, 6 volt 225ah golf cart batteries and at least 200w solar. Alternator is a Prestolite idlepro 190a. Capable of 60% of max amps at 650rpm. Voltage I don’t know. I’ll measure it next time I...
