EV Modifications

hi i know this is really out there ,,,,, but wander if possible 4 wheel jeep disconect rear driveshaft ,, rear axle bolt on direct dc motor like the new ones by warp that have direct drive hookup .a hybred in a sense ,, best of both worlds ?? ,, weight may be problem and cramin batteries in it ,,butttttt .. any positive replys ???thx

So I love my E36, but it always ran hot for me. After blowing a couple of terminal connections, some wires finally melted together, and it shorted out. I had always wanted to make it into a 48 volt, so why not now.

I am the proud owner of two Aprilia Enjoys. A few weeks ago a received the Ping battery I ordered to replace the old (6 years) and bad battery which gives 24V and 12V to the controller. Since Ping's battery is 24V, I put a 24V to 12V reducer in my bike, in order to feed the controller both 24V and 12V. This works GREAT for about 30 seconds. Then the reducer stops giving 12V. When I take the current of completely and reconnect, it starts giving 12V again, but when I start riding my bike, the 12V stops after about 30 seconds, and so on........

I have a new eGo cycle2 and I was curious if it is possible to construct a device with a switch that will allow temporary speed/power increase? I know little of electrical engineering, but I can pick up what I need to if someone is willing to help. There is room for more batteries, so could those be activated with a higher voltage running through the system? Will I really achieve higher top speed without changing the gear out to something bigger?

Thanks!

if anybody was able to convert their 36v e-bike to 48v and would like to tell me if they were able to fit in ev global battery compartment with the original charger pack with all the bike original options working ie headlight ,tailight.cruise control. and would like to tell me where to by the battery. i would love to hear from you. i have about a 20 mile trip each way to and from work and would love to make my trip a little faster and have power all the way home

Iv'e had my HCF 707 scooter for a few years, and its the best scoot i have had. I use it every day for 2-5 miles. I hit a mud patch and the thing fried... smoke coming out of the battery box area. I want to UPGRADE the Motor, Controller, and poosibly go to NiMH batteries.
ANYONE HAVE EXPERIENCE WITH THIS UPGRADE / HAVE ANY SUGGESTIONS?
I'd REALLY appreciate any help / advice / experience you may have.
Thanks, Jim

POWER METER
I have a led bar.1cm wide 35 cm long.With 15 led lights on it.Realy nice looking.What I want to do is ,to build a power meter.Like the kind you find on car booster packs.Push a buton ,And depending how many lights lihgt up,tells you how much power you got.1 light dead, 15 lights full.This will be based on a 72 volt pack.

Power converter
I need to convert 72 volts to 30 volts (give or take 4 volts up or down) for my cooling fans . 2 so far, equel 24 volts .2 amp.Will go to 3 fans if it makes it cheaper or easyer.Dont want to use resiters.

Hi,
I'm legally blind and can ride a bike good, but I need some long distance transportation that doesn't require a shower after a few blocks :)
I found a 24v trike. It uses a 750w motor, etc...
I found a Honda 1000 gen inverter to run a dual pro 30 amp charger & batteries to handle that kind of charge...

My question / concern. I want to charge while I run.
do I need a voltage regulator for my controller?

Battery operation is 24v, but if being charged, it could rise up to 30v... ???

My 36volt Heinzmann system works great, and has for many years, I was wondering if I have to change the controler (which i can for $80) to attach a 48 volt power source. I've read that upping the power from 36-48 is doable in a brushed DC motor, which would make this motor just fly. I also don't want it to burn-up right away either, but the system is overbuilt as it is, and only gets warm after 3 hrs of constant use, never hot to the touch.

---------------------------------

Systems so far:
36 volt Heinzmann, ~8yrs old
36 volt Bionx, new
