Hi guys, this is my first post, but i have been on here a lot through Facebook. My brother and I are building an electric vehicle. It will feature a WarP 9 motor and a Soliton1 controller. This combination can deliver 1000amps continuous up through 300v. We will not be taking it that high haha. We plan on running 10 batteries in series for a total of 120v. This leaves a lot of room for upgrading when we want it faster and helps keep costs down. We have looked into Lithium already and feel that with our budget (as low as possible!) it is not a viable option. It also has to do with our confidence with on road charging of lithium on a cross country ride we are doing to help benefit Breast Cancer research (more on that at the end).
The controller will be water cooled, thus it can do 1000amps continuous, granted we will never see it for more than about 30 seconds for hard accelerations and speed runs. The vehicle will weigh under 2000lbs so it should haul some serious ass. Math says 180hp and about 200-300ftlbs of torque but that's for another thread haha.
The main question here is would the XP3000 battery work in place of a D3100 and be able to put up with everything? It says on the site max discharge of 3000 amps so we are not close to that. It weighs less and has a higher capacity (both pretty negligible) but the biggest point is the price! They would significantly reduce the cost of the battery pack. Plus we are running them for the 12v aux system anyway (2 of them... got to have a good stereo). If anyone has any experience with these bad boys could you please chime in because we really don't want to make a bad decision... Opinions are welcome too.
On the topic of the Breast Cancer, this vehicle will be dedicated to help finding a cure. Our mother was diagnosed about a year ago and can happily say she is a survivor. It was caught SUPER early and she went through radiation (not chemo) and is now doing better. She is on meds for the next couple of years and has to go get regular checkups to make sure everything is ok. Needless to say, it took a HUGE tole on our family and we would do it all again in a heartbeat if we had to. My brother and I want to see a world one day that doesn't have anyone who has been hurt by Breast Cancer (or any cancer for the matter). We are driving the vehicle from Tampa, FL to Grand Rapids, MN where it will be shown at The Geek Group (non profit organization, www.thegeekgroup.org). Lithium has its issues with continuously being fed current and still isn't safe enough for us to fully trust. Lead is tried and true and its easy to work on, and is VERY forgiving. On this ride we are going to stop though many major cities and hold events to help raise money and EVERY CENT RAISED WILL BE DONATED. We are OK with eating the cost of the trip (requires gas for the EV to run the recharge generator, hotels, food, and for our chase truck... just in case). The panels will be painted black with a pink ribbon raised off of the panels. Anyone is welcome to sign the black areas, and donors are allowed to sign the ribbons, all in permanent marker, which will then be clear coated locking in the signatures forever. Multiple panels will be made so they can be swapped out when they get full. I would LOVE to see six figures at the end of this trip, all going to charity (it will all be documented by the books of course), I know it is a lofty number at best, but we both have shown that you can do ANYTHING if you put your mind to it. It's like this massive inspirational story that I don't want to get into right now haha.
The vehicle is a custom built 4seat tube chassis that uses a VW front and rear end. 1965 Beetle up front and a 1970/72 bus in the rear. It is built to NHRA specs for a roll cage and will protect anyone who is inside in the event of a rollover or crash. 5 point harnesses and Corbeau racing seats at for all 4 people, safety was kind of a big deal. It has a 3rib bus transaxle and should top out a around 100 due to gearing (the bus was geared LOW due to low hp). It should easily smoke the tires (or the clutch haha) in 1-3 with 4th for cruising. Nothing like all of your power and torque at 1rpm!
Sorry for the long post, the really important stuff is in bold for an easier read.
Thanks for the help in advance!
