Well, due to some weird stuff and bad luck happening on my 2WD project, (see my recent posts in the photos &videos section for info, if you are curious) I've decided to go with a single high amp controller instead of using the dual WE brushed hubmotor OEM controllers.
Since I know that I need at least 80 Amps and will be running a nominal 40V (rather than 36 or 48) I'm going to have to go with something pretty "beefy" The question is: which would make more sense, Modifying a YiYun or just buying a Kelly??
I have some experience and success in modifying a YiYun for high voltage, but considering the horrible luck I have had on everything related to this 2WD project, I'm a little hesitant to do anything that isn't idiot proof.... Plus by the time I order all the parts from Digikey (4110 MOSFETS, 40100 Schottkys, Capacitors, and assorted other items (I would order more than I actually need, for spares, future projects and to get the price breaks), I'd be spending nearly $100 and wasting another day in labor.) At least I already have the controller to modify, so I wouldn't have to spend any extra getting one of them....
If I order a Kelly, I can save the labor, probably some frustration and probably get something more reliable, for a fairly reasonable amount of money.
Under consideration are four of the Kelly's: the KDS48200 for $170; the KDS48100 is only $130, but is kind of borderline for the 80A I may need for more than a minute at a time, occasionally.. and the KD48200 for $200. or the KD48201 (regen) for $230
I could save a little money by going with the 36 volt models of the above, but with a fresh charge on the batteries, I'd exceed the max voltage for a few moments on startup, and who knows, I might eventually decide to run 48V when I can afford to buy more batteries.
On the KD48200, the electrical specs are about the same as the KDS48200, but it has the programmability function... which I like, but is twice the size of the KDS units, ....And I'm trying to be as compact and stealthy as possible.
Same with the 48201; plus, I don't know if the regen would be of any use to me at all... I get the idea from other threads that I have read around here that regen for the sake of extending range on bikes is by far more trouble than it is worth, especially if you are running lithiums.... And while I like the idea of regen braking assist, I don't know if it is worth the extra money and the extra hassle.
So, what do you guys think?
