Ok sorry to jump in here am rereading this thread as I am awaiting a yosepower 36v 350 hub and bits to build batteries, saw this from

Hall sensor wiring 8 or 9 /wires = sinewave
No hall sensor 3 wires only = square wave.

Both controllers are hall sensor & sine wave both give quieter smother operation the only difference is 15a one is for 36v though can be used up to 12s with max 4.15v max cell charge to be on the safe side 4.1v, it has waterproof easy fit wiring.
17a version is a dual voltage model so can be used with 36 or 48v even to the point of using trying up to 15s to a point if so wished.

If the requirement is to use 36v and in need of a few more amps/watts then a simple shunt mod on the 15a controller can increase power output by another 25 or 30% if required.

................MY QUESTION IS ............
What if Ibuilt a 12s (or 11s or13s ) Battery what would that do to the whole setup, just throwing this in here as I am also new to lithium batteries, though a friend has more experience, maybe its not even possible or worthwile??, ok back to rereading 3rd time around
thanks in advance
In battery terms 11s is a non starter if you want to use a bms, 12s makes sense both bms and chargers for 43.2v nom are available.

not going to use a BMS, will charge with a hobby charger that will do balancing, there are 11s BMS available though, but thank you vfr400 for the info about controllers not working well with internediate voltages. will first do it right before playing, was thinking out aloud

AK's KT seems to work well with 12s.

AK is short for forum user 'Anotherkiwi' who lives in France.
KT is for ' Kuenteng 'electronics ' who make controllers/kits, one of the most widely source able bits of kit on the market. They are very good and make controllers in varying sizes with various functions, can be bought with older style wire connectors or Julet waterproof ones.

I heard my name...

I still use 12S because I have a couple of balance chargers on hand but my battery is now 2x6S Li-Ion connected in series. I wanted 12S to reach a certain RPM to prevent back EMF problems I was having.

After some testing I think 13 or 14S and a new 48v controller is probably on the cards. I will probably buy or maybe build a couple of 7S batteries with BMS and chargers. That way I will have 2 x 13S (7 + 6) batteries, handy when I need the two bikes and when want to go far. 14S 48v is ideal for pushing the trike along at between 45 and 50 kph...

What ever did happen to d8veh? I was just looking back at some old posts and it crossed my mind!

A while back I asked about the spacers for the rear hub and if they should be on the outside or inside of the frame. The reason I asked was that after leaving them on the outside all vibrations in from the hub motor disappeared.

Now, after having done another 300 miles I've noticed that this wasn't because of the spacers but rather my new 17A controller that Yose sent me as a replacement. The hub is more or less 100% vibration free and it's a big differene in both feel and sound.

That's how I feel about the after market dolphin mount controller I purchased, I still think the YOSE controller was not the best controller for a 350w system and as mentioned it did however work perfectly on my 250w front hub. Hopefully someone will post on here in the near future after buying a new kit and we can see if they change the controller supplied.

Hi Yes Yosepower 350w 36v Rear hub in silver, ( black was not available) , to be used with a custom built battery, plans are to consruct a battery controller box from Epoxy ply, that fits in the triangle. Cant wait till it arrives
