www.forkenswift.com - Just for fun... Q how long does it take to swap out the car's 8 batteries with a fresh set? A: a lot less time than it takes to recharge them!
#7) Project ForkenSwift electric car: battery pack hot swap!

So easy, even a Canadian can do it.
30 to 35 km at city speeds. See the web site for more speed / distance info: ForkenSwift-dot-com
So how far is it practical to drive with this car ?
No – we intentionally chose the cheapest & lightest car we could find (both criteria happen to align frequently with old Metros). FYI, it weighs in at around 1700 lbs in gas engine form.
They’re Exide GC-5 225Ah 6volt flooded lead acid golf cart batteries.
Did you concider the old corolla, with its heavy iron block weighing in at 2200lbs.
Theres a lot of weight to be saved on this vehicle also.
Would you say, a Fork Lift motor would be best electric motor of choice?
Are you using a Long FDR or Short?
Keep looking out, Solars becoming increasingly inexpensive.
Do any body know what type of battery and what is the voltage and ah for each battery.
It is only chaps like you who will, eventually, manage to shame the cynical establishment (‘OIL Co’, GMC.etc ..and ‘their’ Government.) into offering appropriate products at a sensible cost ….. a technology which YOU have proven is quite possible as it’s already here. Keep fighting the good fight.
“Evil prevails when good men do nothing”.
Well done sir.
Great sequence of videos… you truly show it can be done and that as the project progressed more and more safety and acceptance for home builders is happening.. Nice work
I must commend you on your ingenuity. Keep up the good work. I’m about to do a similar project with a dunebuggy.
You’re welcome! And you’re right: need to post some details about performance. It’s pretty unimpressive on 48v with a 400A controller – 25 seconds to 50 km/h (30 mph). Solar would be sweet – super expensive, and won’t contribute much to the total distance driven, but fun nonetheless.
The “new” batteries are really just a set of slightly less dead, used batteries. In warm weather we’re getting around 25 km per charge from them. No plans to upgrade the motor – it can handle much more voltage. We *may* up the pack voltage a little.
That is simply amazing. Thank you so much for the inspiration to get my project started. Great job. Pehaps a chapter on performance(Speeds, distances, etc). Ever thought about adding some solar panels to help keep that charge? Excellent !!!!
VERY COOL!
Have you gaged the total distance for driving and road time yet with new batteries? Also, will you ever change out to a bigger motor? Keep us posted
Haha! Because my chauffeur stayed in the car while I swapped batteries!
But why did you get out of the passenger side? Hehehe.
Nice Job. Sergio form Brazil
Yup. There was only one big one – we’re using it as the emergency disconnect via the clutch pedal.
Did you save those big battery connectors from the forklift? (C:
Friggin great idea dude!!!
Very nice! just need to get some quick disconnections on it like a paintball gun and u can cut ur time in half
awesome job!
The new li-on batteries coming out can be charged from flat to 80% charge in a few minutes, so won’t be necessary. Its that last 20% that will take the time, that can be done at home.
Very cool! In the future there could be a network of places to swap batteries and rent them and this would greatly increase range. Thanks for the vid.
