IHave tried every conceivable combination of quote, reply, copy and paste but yet I cannot get it to come up as a quote. I am stumped.

Here you've just overlooked to add the red bracket (no spaces before and after).

As above and the text has to be between the middle brackets; like that:

Thank you for trying but now I am more confused. Could someone give me a link to where it is explained in step by step fashion. I just do not get it, I need the steps in order. I have no problem over on whirlpool adding a quote.

Cheers and thank you for trying

I think I am over complicating it

Yes, you seem to have it now tony .
PS i added a couple of photo's of my controller internal back on the previous page,..
..and for anyone who is curious here is a pic of the Aprilia Motor armature..
..after several years of 1200W powering running on 40+ volts. !

Thanks HH

I still haven't gotten on to replacing my gears. I have two bikes here needing fixing and no time. Anybody want to buy a silver city with lipo batts and the parts for circa $750 AUD? It's not so hard to do...

I am up to bike number 7, so I might be risking divorce if I bought it. Good luck Sam.

Cheers,

7 !! I've just started changing the controller on the 2nd bike I have after 2 years. The first one is still running well even if the motor does get quite hot at times. The battery did get badly out of balance on one cell but seems to have recovered.

I have 4 Aprilias and they all still work, they are just different versions in different colours.

Another Aprilia racing model for sale in Sydney. At $800 and not working by the sound of it, it is way overpriced but seller is negotiable.

Two batteries makes it more interesting. But $800 is still a bit too much.

The batteries will be the old NMH and they have probably had it. I have got 3 or 4 of these old NMH battery packs (taken out of their cases) if anyone wants them. The fact that he says the PAS isn't working probably means the controller has stopped working.

No doubt they would be the old NiMH. But having extra battery cases I think can be handy and you never know your luck one of the batteries may still be useable. I thought both of mine were stuffed but one at least came back to being at least useful.Still being used but have no idea of the range of it anymore. Just a matter of time till the conversion though I would have liked to have a spare case so that I could continue to use both bikes in the interim.

Just waiting on the throttle and the voltmeter to finish the controller conversion on my second bike. Hopefully sometime this week

G'day HH,
I have opted to order a 36v , 800w YK 31 controller this time ... it seems better matched to the battery.

So, are you going to replace the controller with the one above ?

I am looking at replacing my 8s battery pack with 10s and thought I might beef up the controller .

G'day Tony, sorry I missed you in Moruya. Google found a secret road to get there. The sharp stones between Araluen and Moruya chopped the rear tyre to the point it was getting flats every 50km or so. Had to be replaced.

The reason I didn't opt for a 36 volt controller is the low voltage cut off is set too high for my 10s LiFePO4 battery pack. It will also be too low for your 8s pack. A 36 volt controller is not any beefier in terms of current and 36V will not exceed the voltage rating of the components in the 24V controller. The only difference as far as I can tell is the low voltage cut off setting. I use the BMS rather than the controller for that purpose. I've also noticed that buying the same model controller from a different supplier gets you a different controller. Same functionality and connections but a different dimensioned box and different internals.

I've ridden in the rain with the changed controller placement detailed previously and not lost power so that is a nice improvement. Basically, make sure the wires exiting the controller point down and not up because water coming off the front wheel is like spraying it with a garden hose.

Thanks for that info Ken and what a bugger about the tyre. Next time you go for a long ride and maybe make it to Kianga, the offer to stay is always open.
Cheers,
Tony.

Ken, you are spot on that the 36v controller has similar current limits to the 24v version.. (so probably the same power handling), and that the 31v LVC is too low for 8s lipo, but that is exactly one reason i wanted to use it...a little extra battery protection fo my 10s lipo pack.
And again, yes these controllers are different depending on where you get them.
My original YK40 24v (pictures back on pg 34) had only 3 power FETs, but i noticed that yours had 4 FET's, and now this 36v YK31C has 5 FET's ?. ..And all seem to have 50v rated components.( so dont try more than 12s ! :lol: )
but damm, its board size is even smaller than the YK40..literally it doesnt even half fill that tiny controller box. !

I note also that this one doesnt have any of the rubber sealing gaskets on the end covers that the YK40 has ?

I've noticed the difference in size. I just bought another 24v controller and its noticeably smaller than the first one I bought. It ends up being a better fit. Has anyone tried modifying the cutoff voltage of one of these units. I'm going to use one of those Hobby King 2 wire low voltage alarms and try and change the alarm setting value but having the controller cutoff at a reasonable value would be a handy backup. At the moment I use the alarm that plugs into the balance leads but its too easy to forget to put it in or take it off. I certainly don't trust the kids to remember.

Guys,..cheap lipo power !

9s (33-37v) 3.3Ahr zippy lipo packs for $20 from the Au HK warehouse !
6 of those ($120 ) in parallel would give a nice 20Ahr 36v pack that easily fits in the battery compartment.

A controller low voltage cut off is better than nothing and at one stage I was thinking of modifying a hobbyking alarm to do low voltage cuttoff using the brake switch input. The parts are cheap but it's not a great solution. One low voltage cell can go too low while others are high enough to avoid the sum of the cell voltages tripping the LVC. It is better to monitor every cell.

I'm sold on a BMS which does LVC, over current cut off which is essential for avoiding explosive LiPo fires in the case of a short circuit, high voltage cut off and continuous cell balancing. I've found BMS battery protection to be set and forget but I wish they incorporated a fuel gauge that showed the state of charge of the battery. A gauge on the battery is more accurate than on the bike because it would see all charging and discharge current. There should be a liquid crystal display on every battery pack displaying its state and properties.

When I go to this link it takes me to the international warehouse and when I go to the AUS warehouse it says these 9s batteries are not available?
I must be doing something wrong.
I have an accucel 8s charger so what would I need to buy to charge/ballance these 9s batteries and would that defeat the savings on these 9s batteries?

Tony.

I know what you are saying about the risk of one cell going low and not being picked up by that sort of setup. Its more a case of just another warning system. As I'm not the only one who is riding these bikes the more protection/warning the better. I would still use the alarm monitoring for each cell but I just know the kids will forget. I haven't come across a BMS for a 6s setup but admittedly I haven't looked too hard.

The throttle arrived today so I have now been able to confirm operation . Motor runs, brake cutout works and theres a nice satisfying beep when turning the key. But I'm still waiting on the voltmeter before I can put it all together properly. Its a slow wait out of China
