  1. Best smartphone/desktop navigation for EVs?

    All EV Conversions and Builds
    Hi Everyone, I recently bought a KIA Soul (2017), and I've been wondering if there are any reliable navigational softwares or sites that I could use for planning my future trips, maybe even calculate what range I can cover. So far, I've been using abetterrouteplanner. However, I just...
  2. EV total range variation based on motor size

    EV Performance
    A friend of mine had an E-trike that worked on a 1 KW motor and had a curb weight of 350KG and had a range of rougly 40 miles using 48V/100Ah Lead acid batteries at 20-25 mph. Is it safe to assume if I have a similar build but replace the 1 KW motor with a 5 KW motor that I should still get...
  3. EV total range variation based on motor size

    Technical Discussion
    The e-rickshaws in India come with 1kW motors and have a curb weight of 350KG and regularly do 70-80kms using 48V/100Ah Lead acid batteries at 20-30kmph Will it be safe to assume that if we replace the 1kW motor with 5kW, we should get the same range if we drive at similar speeds and everything...
  4. New to the concept

    New Member Introductions
    My thoughts of converting a car to electric power began when I couldn't get my 93 Geo Metro running right. While searching for tips on youtube, I watched several videos featuring them being converted. I have since corrected the problem and am once again happy with my pregnant roller skate...
  5. Putting batteries in parallel to give you a bigger range?

    Batteries and Charging
    Hi, I am thinking a little ahead to when I get the batteries and controller. Currently I intend on getting a 72V controller due to the fact that they are cheap and easy to get (probably a Curtis one) according to my ebay searches. I also intend to get 12 fairly cheap and cheerful 110 Ah...
  6. Range and performance of My EV

    EV Performance
    Performance can mean different things to different people. Spinning the tires and running the batteries out in seconds will impress some. For me the challenge is to go the distance on as little energy as possible. So, this weekend I broke a new personal record with my homebuilt EV. I drove...

    Hey guys i have a quick question about my electric scooter, so i purchased a razor ecosmart metro 36 volt 21amp electric scooter 2 years ago and the battery used to last me about 5miles but now it only lasts about 1 and a half :( i was wondering how i could increase the range (and hopefully...
  8. My Electric Saturn with new Lifepo4 batteries

    All EV Conversions and Builds
    This last Winter I was busy installing new Lifepo4 batteries in my Saturn SC2. These replace the nine lead acid batteries that gave the car a range of 12 miles. Last weekend I drove the car 40.4 miles. I was thrilled to get that close to my estimate of 42 miles with the 36, 100 Ah cells that I...
  9. back seat/trunk battery

    Batteries and Charging
    Does anyone know if I can wire a secondary battery to my existing battery for an EV or directly to a motor and flip a switch to draw power from it when my EV battery is out of juice? So if I am in a remote area with no charger, and my car is a full EV, can I use a battery sitting in the...
  10. Wheego Whip review

    Production EVs
    Wheego Report: 3 Months After several years of wanting, planning & shopping for an EV, I found what seemed like a good deal on a 4 year old unsold new Wheego. The important features to me included an HPEVS motor & controller and Air Conditioning. After driving it for 3 months, I don’t have any...
  11. higher voltage vs. more amp hours

    Batteries and Charging
    I have a Warp9, a Soliton Controller feeded by 47 CALB 130Ah cells. First we had 36 cells, than 45, now 47. But it seems that the more voltage doesn't mean that we consume significant less amperage. So if I want to increase the range, would "more cells" and higher voltage or bigger cells with...
  12. Peugeot 205 GTev

    All EV Conversions and Builds
    OK, here goes. I'm currently trawling the internet for the best way to convert a 1988 Peugeot 205 GTI into an EV (hence the probably obvious reason why I'm now a member of this Forum) The plan is to use it as a day to day car commuting to work and to the shops etc. I'm lucky enough to own...
  13. More Range

    Technical Discussion
    I'll use this 288V 160A/h battery pack, how could I get better range? using it like a two 144V packs in paralell, so I'll have 320A/h, so I'll have more output Amperage, or using it like one 288V battery pack? or is the same? (Batteryes are Lipo)
  14. What motor and amperage should I use?

    Technical Discussion
    Hi,I'm trying to convert a Mitsubishi Lancer, because it is not a heavy car, and also I like it and it has enough space for the batteryes. My question is what kind of motor should I use? I've seen a FB1 4001A or a Warp 9 (they are almost the same), as you see I'll use a DC system. Are those ok...
  15. Diminished range on new battery pack!!

    EV Performance
    Hi All, Scratchin my head here....just installed a new set of Interstate 8volt GC8-HD-UTL batteries (9) and have about 500 miles on them. I originally had a range of about 25 miles, but this last week it has dipped to about 8 miles, which is luckily my total commute, but barely made it...
  16. adding more batteries questions.

    Batteries and Charging
    I currently have a 96 VDC system with a curtis 1231C controller and a Prestolite MTC 4001 Series Wound DC 20 hp motor, lester 96VDC charger. I plan on adding 4 additional 6VDC 232aH batteries under the back seat of my car. I am adding the same brand and model of batteries. Also my current...
  17. Wayland's 350Mile per Charge Honda Insight BEV

    EV Performance
    Heads up here comes Silver Streak: See Link for details. Crazy Highlights. John Wayland's Gen-1 Honda Insight is being rebuilt for long range BEV. 350 Miles per charge at highway speeds of 55 to 70 MPH. 71.5 kwh battery rated for up to 715 kw of discharge power. He is expecting to get about...
  18. 48V or 72V? Watt/hr + Peukert, etc.

    Batteries and Charging
    I was going to go with 48V for my motorcycle. 48V X 55ah = 2640 watt/hr. If I go with 72V X 38ah, I get 2738 watt/hr, roughly the same. I am assuming that purely from a range standpoint, the 72V system will go farther because of less current draw and therefore less Peukert effect. Or do I just...
  19. Trying to Diagnose my poor range

    Batteries and Charging
    I've got a 72v system using 9 8-v Eveready golf cart batteries and an Alltrax controller and a D&D motor on a 1971 Beetle -- basically a Wilderness EV setup that I bought almost finished. I'm finding a maximum range of 10 miles in mixed driving, which seems low. Since I don't know the car or...
