hi all, is it possible to convert a 72v crystalyte controller down to 48v,,,can the LVC simply be removed or is there more to it than that, is there pics showing where the LVC is and how to go about that type of mod?

is it possible to have 72v40amp controllers built without LVC therefore allowing any volts to be used,,,so i can use anywhere from 36v to 72v....of course i know the batteries will not be protected,,,, if in fact i were to have 36v - 72v controllers would there be reliability issues? is it...

Hi all, I got an email from one of my clients this afternoon pointing me to this thread, up until this time there were a few people who were asking me about the CA plug on the new sensorless controllers, I honestly thought it was just a matter of calibrating the shunt, but obviously it is not...

hi everyone,maxwell65 here, i just found out about the issues with the controller as one of my other clients found this posting about it and asked for my help,otherwise i would not have known. first to rechargeourfuture,i really appreciate the fact that your so nice about the whole experience...

well of course you did,it all goes towards a worthy cause,a betterment to the world so to speak, :wink: i make no secret to the fact that the only motor i've used so far is the 5303,and of course i know about the fact that the higher the # the more torque less speed factor,however i still have...

is a 5304 more efficient, then a 5303? is a 5303 harder on the batteries upon takeoff,whereas the 5304 is easier on the batteries as well as the controller.and is the 5305 even more efficient than the 5304?would better range be accomplished with the higher torque less speed 5305 than lets say...

is there a problem to have 72v80ah lifepo4 battery pack with a 72v50 amp controller, i suspect not as the 80ah is representative of the amount of power stored in the cell,but i have to ask. :oops:

i just want to say im not suggesting not to use a bms,as i have every intention of installing one,im just saying that if a bms stops working properly the possibility exists to keep on charging by other means.

well now you know about the prismatic's and why there a lot better :) forgive my sense of humor kim ,of course im just kidding,yes the duct taped ones are lighter and less bulky,but the prismatics are easier to maintain in terms of replacing a dead cell if need be,and as for me i like to be in...

the fact that my BMS died over 2 years ago and i was left having to go back to SLA for about a month until i was able to gather the information that in fact i was able to charge manually,and the fact that i have been charging manually for the last 2 years and my pack is still perfect,is the...

This article is in 2 parts: part 1:direct comparison of sealed lead acid batteries & lifepo4 part 2:BMS facts and how to charge lifepo4 without it! This article is about batteries and my personal experience with both sealed lead acid (SLA) and lifepo4 batteries, and most importantly how to...

hi doc thats really weird cause the M switch is suppossed to be medium,,,the H switch is supposed to be high,,,and normally the H switch is neutral,,,in other words the H is not doing nothing except letting the full current through,,,so the controller with or without the switch it should be H...

hi all here is a diagram of the hall sensor wires i got from ebikes .ca ,,,hope it helps i have used it to swap out my old plug on my 5303 to the new mini xlr and it is accurate
