Re: My Dusty 71 GMCe Electruck
for safety reasons you can't just hook up a Multimeter to a high voltage battery pack, you essentially need a car battery to turn on this battery

Re: My Dusty 71 GMCe Electruck
that's why we remove the lid and bypass the Pre Charge Circuit which contains contactors that otherwise have to be powered up, but this being a German product it ain't all that easy without fandangling with the BMS first I think, so forget that
not bad, that's 346 out of 351 vultures |

Re: My Dusty 71 GMCe Electruck
I did the same to only one of the six cell modules that are inside that battery pack
57.7 out of 58.5 that's pretty darn good |

Re: My Dusty 71 GMCe Electruck
I also took the opportunity to weigh one of them, and it came in at 27.7 pounds
so six of them only weigh 166 lbs, so if I double that it will be 332 pounds anybody know what a fully dressed Small Block Chevy weighs for a stare and compare? |

Re: My Dusty 71 GMCe Electruck
I’m seeing weights from 530-575 pounds.

Re: My Dusty 71 GMCe Electruck
thanks so that covers three of these packs which adds up to 498 pounds.
I am thinking we could add another 100 pound allowance for a full 16 gallon fuel tank full of gasoline (16 gallons x 6 lbs = 96 pounds) plus 10 lbs for 6 quarts of oil, plus the weight of the exhaust system and I think we are breaking even, even with four battery packs at 665 pounds. |

Re: My Dusty 71 GMCe Electruck
Think it is cool what you are doing. Electric performance and torque is real.
None the less I would never own an electric or do a conversion myself except for a local driver. Curious if you know what the motor/trans weighs. My aluminum block LSA 6.2 with 6l90 is in 700lb range. The 31 gallon tank I am installing full is around 200lbs. 31 gallons should allow over 400 miles range as long as I keep my foot out of it. What is the range you are expecting?

Re: My Dusty 71 GMCe Electruck
Nice video. I did not realize the batteries were in series but I suppose that makes sense to get the higher potential. What is the voltage and variance that the motors are rated for?

Re: My Dusty 71 GMCe Electruck

the pack I am using is from a different plug in hybrid car a BMW 530e which had a 350 volt battery pack. Based on the world's #1 best selling electric car, the Tesla Model 3 and the world's #2 best selling electric car the Nissan Leaf that's all we need as they both run 350 volt packs. It's what I call a full voltage pack. Of course they have a much larger fuel tank capacity if you will than my little 9.1 kWh one. hope that answers your question Last edited by Gregski; 12-12-2021 at 01:18 PM. |

of course you are talking about power and I am focusing on capacity, I get that but the thought of doubling the voltage to over 700 volts did enter my mind if for nothing else a shot down a drag strip [Note To Self: upgrade front drum brakes to disc, lol] |

Re: My Dusty 71 GMCe Electruck
What range will you get with 4 packs?

Re: My Dusty 71 GMCe Electruck
thought you guys might enjoy this video of Jerry installing the same electric Tesla brake booster I am about to use in my EV Conversion in his 1995 electric Hummer

Re: My Dusty 71 GMCe Electruck
I got a chance to completely disassembly my BMW 530e high voltage battery pack and would like to share a video with you

Re: My Dusty 71 GMCe Electruck
those pics are on top of a 2 foot by 4 foot piece of plywood for a size reference, looks like I can fit 9 batteries in that space

Re: My Dusty 71 GMCe Electruck
yeah, it's winter and I am procrastinating, but when these brand new German (pronounced: "Expensive") BMW high voltage battery cables showed up, I decided to treat 'em right

Re: My Dusty 71 GMCe Electruck
Why you ask? well we are trying to connect this German BMW 530e high voltage battery pack to a United Statesian Tesla Model S battery charger so that we can charge it and it's like fitting a square peg in a hole that's round

Re: My Dusty 71 GMCe Electruck
now we can provision a much more civilized connector such as this handsome Anderson SB120 in crimson red
