thanks for the input guys - I think im going for a lightweight quad, ag road registered. It would be nice to build an ultralight, but time and projects intervene.... argh - after swmbo is informed of this salient decision, she has suggested this instead as it allows her to use it too -...

OK - first long term weekend music festival test done. Averaged about 50wh/km does that sound right? Andersons bought and installed - tiny arnt they? batteries - MK gel batteries 22Ah's x 3 x 2 iyswim provided a day and a halfs festival running after a crazy 3yr old across a field before I...

No 250cc farm quad is anything like 50hp - sorry - my butt dyno tells me its sub 20hp - they are torquey, not powerful like motorcycles (yes, a 250cc bike is 50hp ish) from some tinternetweb trawling, Ive found figures from 12 to 20hp being stated as 'fact' - with most being 15 or 17hp

Yes - in the UK you can ride an ATV on the road - no helmet or seat belt. Its also going to be 'agricultural registered' - the same as a tractor, so it requires no annual roadworthiness test (MOT in the UK TUV in germany etc) or annual road fund duty (aka road tax). also requires some lights...

Been sold a brand spanking new goldenmotor HPM5000B watercooled motor and HPC500H controller, and a veritible pile of 48V LiFePo batteries with built in charge controllers, each 10Ah. Well under half price - Im not going to make you sick. ;) I live on a rural small farm in the UK with...

found the fault - transposed throttle wires. doh. :wink: ah - anpaza's thingy is linux? Sorry windoze / android only here Edit. Recieved reply from paul,with wire connection explanations. The two white wires enable regen braking on 9+fet models, and set voltage on 6 fet models. I have the 9...

I have searched - promise! I have go the 'programming' cable from E3EMV with a USB plug on t'end. I cant seem to find the actual software anywhere - the odd reference to a 'flash' product, and a screen shot or two. Any pointers please? My problem - I have plugged it all in and it worked...

Thanks - the throttle I think has a three speed switch iirc. maybe Ill glue it onto #1 ;)

Thanks - there is an additional point that this vehicle will almost exclusivly be used 'from' our base in a RV - which is based on a 10 ton truck - and is all 24V. It has a pair of huge 24v solar panels on the roof, so we can re-charge SLA for free from the solar. No - Im UK based - but I used...

Thanks I dont thin she will be using anything like 30a continuous, as that would equate to a frightening speed in a wheelchair on grass. I have hopefully massivly over specced the drive power to allow for very very brief situations where the extra grunt is required. The normal use is a gentle...

right - back at a proper pooter so I can type better. what Im asking is:- is 3 x 10Ah batteries significantly worse for my application than say 6 x 5Ah wired both options for 36v / 10Ah? (taking 10Ah as a base line for arguments sake - the same applies for 15 or 20 or 30Ah - its just the...

Well, it does with a 200w motor and 7ah battery bank. Just.... Yes, knobblies are a must! I want two, separate banks, as one is to be used whilst the other is being charged up. I cant see how i can do this and keep them together :lol: Probablya typo...10 vs 30ah. Or wine related typing on...

Thanks. Ard you saying that the 30a will be inefficient at lower currents? I went for the slightly bigger controller for the few ten second bursts when she is going uphill through mud. Hopefully she wont be going everywhere at full throttle, considering how crowded these events are...... The...

I know that 99.9999% of the time slas are a bad idea, but in my unique case, they are ideal I have a front wheel drive trike adation for a wheelchair for my wife. She needs this to get around music festivals in a field. the traction is provided by the weight of said sla batteries. I want to...
