    Looking for a motor for an EV conversion

    gruntguru - I've looked at EV batteries and I really wish they came with a warranty. To solder these batteries, looking at other videos of people making them, I'm looking at around 180 hours of work at around 15-20$ per hour; the price jump from the next cheapest pre-built option which are the...

    Looking for a motor for an EV conversion

    edit: nice, i didn't see your last post when i first read this. Yeah, definitely, i'm stoked to try and wire the batteries myself. I'm really concerned about the weight, especially with the current size of the engine. Yeah, I know the housing will take up some weight but i still think it'll...

    Looking for a motor for an EV conversion

    ok, cool, this helps a lot. I'm told I'm supposed to have a 300 volt architecture. Nominal voltage for each cell is 3.6 volts so thats around 84 cells per segment. I plugged the voltage architecture into the calculator and the number of cells into the amp section (i'm guessing one amp each)...

    Looking for a motor for an EV conversion

    I sent Elaphe an email. I have a feeling they may be out of my price range but it looks cool and is definitely worth checking on. I have a serious question. I'm looking at buying a hell of a lot of 18650 cells and connecting them together for a large battery system for the build. I heard...

    Looking for a motor for an EV conversion

    the batteries i'm looking at have a density of 61 watts per pound. I'm going to be putting around 80kw of batteries so that's around 1300 pounds. nowhere near a ton. With my weight i should get close to 200 miles on a charge (atleast thats my estimate unless you see differently) I'm also...

    Looking for a motor for an EV conversion

    I grant you I haven't found anything that seems to fit the size of my motor currently, however, it took me 20 seconds to find a larger EV transmission for commercial vehicles and truck applications. https://www.eaton.com/us/en-us/catalog/emobility/4-speed-ev.html I also found a 2 speed...

    Looking for a motor for an EV conversion

    Yeah, i realize going 55 on the highway isn't ideal. I'm looking at the high roof 144 wheelbase which i think is like ~5000 lbs curb weight depending on year. I'm thinking 2k lbs load is safe. And i can always avoid the steepest paved road in utah. I just need to make sure i can go slow up...

    Looking for a motor for an EV conversion

    Well the good news is the curb of the sprinter is 4500 lbs and i probably won't be adding more than 1500 lbs including passengers. I also need to be able to get up the 13% grade i-80 outside slc. so thats: 2700 kg x 9.807 x 0.13 x 25 = 86kw Does anyone know where i'd start trying to put a...

    Looking for a motor for an EV conversion

    Hey Brian, your response has been very helpful. Bill, thanks for the idea for the Tesla motor. I didn't know that some EV conversions don't have transmissions until i saw jehu garcia's youtube channel and started getting responses here. I understand that vw busses would be cool. It's changes...

    Looking for a motor for an EV conversion

    I'm going to be converting a class b motorhome, most likely a sprinter, into an ev vehicle. I heard the new electric Mercedes have a 84kw motor (120hp) with 300 newtons (220f/lbs) torque so i thought I would model my needs off their specs. I found a few motors that were close on the hp but not...
