The "Y-cable" arrived yesterday. It is called "Super Soco Battery Paralleler". It's huge! (about DIN A6 postcard; 11.1 cm x 14.8 cm) It's thick! (5.0 cm). It's heavy! (904 g).
It's filled with resin which covers the circuit board completely.
It has 3 cable connectors: to battery #1 (~30 cm), to battery #2 (~30 cm), to charging outlet (~50 cm, 2x 0.75mm²), and has one socket (to controller/motor).
It's function is as far as I could test it yesterday:
1. Connect the battery with the highest voltage to motor
2. Connect the battery with the lowest voltage to charger (connector below the seat)
3. Toggle every 15 seconds the 2 battery CAN-BUS's so that the display reads the different SOC's every 15 seconds
It's very smooth use: the motor is a bit stronger because it stays longer on a higher voltage (always optimal battery). No increased power apart from that. The charging also goes very smooth (saves time because you cannot forget the change the charger). The battery connectors get much less warm.
The connector cables are a bit short and the box is really bulky. It does not like when the two batteries are both charged to 100% manually (then the display flickers to 0%, that is just a cosmetic issue). This does not happen if you charge the batteries with the paralleler box or when the SOC is below 100%

So most importantly is the range is increased with less wear on batteries and also where does the paralleler mount into on the bike? Do you have to remove panels to install it?
the range stays the same
key benefits are:
* ease of use, you do not have to swap batteries
* the power of the motor is stronger during a longer distance because the battery voltage stays high for a longer time >65 V
* there is no wear on the fragile battery connectors because you do not unplug them anymore
* on a minute average, the mean current over the battery connectors is cut in half to 20A (if both batteries have about the same SOC). This prevents overheating and molten connectors (Super Soco France has just modified the firmware of the controller cutting the current from 40A to 35A in order to prevent overheating, beware of this firmware if you want power)
* connects always the emptier battery to the charger, you do not have to change the charger (cutting charging current to half which is better for the battery)
But: Your Super Soco does not get more range, does not get faster and does not get up on steepter hills (even it stays fast for a longer time because SOC does not fall off so quickly).
The module is installed on top of the batteries (without tray)
OR
below the right side panel which has 4,8 cm of air space (so it fits extremely tightly there) + you need to turn the socket on the upper battery + you can use the tray
OR
below the left side panel with a cut out tray
Key disadvantages are:
* price
* it has a software bug and reports 0% SOC to the display if both batteries are at 100% (cosmetic issue)
* it increases the weight of your bike 0,9 kg
Great thanks for the post... very interesting! So does that mean you could technically connect a battery at 50% and the other at say 90%? Is it using both battery at the same time?
I wonder how it draws power from both if this is the case? Its weight must be part of the reason....
it just discharges the battery with the higher voltage and connects the other one to the charging port
usually higher voltage = higher SOC but there may build up up to 3% difference between the batteies before they are switched electronically
I wonder that the circuit of the paralleler box needs some power for its own and might discarge the battery faster when not in use, not sure.
Hi
Can anyone tell me were to buy the battery paralleller if you live in Europe?
I guess that this is NOT the right one?

The "Y-Cable" from Outdoordreams is the "Battery Paralleler". Correct.
I have installed mine below the right panel. I had to open with a Dremel multifunction tool the plastic container of the battery compartment so that the cables fit without bending the box. I also re-routed the main power cable (to the motor) to have more room to place the battery paralleler. I had to open some screws for that in order to have enough wiggle room to re-route the cable. I fixed the battery paralleler to the frame with a rubber band and the power cable to the socket of the paralleler with another rubber band (the socket does not hold well the plug, the data pins have a loose connection).
I also had to turn the socket of the 2nd battery. You need to apply gentle force, it may take 15 minutes or so until it comes free. (I broke a kitchen knife during my intents - so do not apply big force, the socket comes free with wiggle, it is only glued with kitchen silicone).
The paralleler gets warm during use and during charging, so it reduces a bit the efficiency of the bike. The charging time with the standard charger from 30% to 100% is about 11 hours.
If you have 0% in the display permanently, then it is the loose data pins at the socket of the paralleler. You may have to fix the cable with a rubber band so that this does not happen.
Without the paralleler I need 51 minutes from my house to my work. With the paralleler I need 50 minutes (no stop over for battery change). As you can see there is no power increase of the bike. Without the paralleler I got back from work with 122% battery use, now it is 133%. I do not know if it is the paralleler or the lower temperatures now (15°C instead of 20°C a week ago)
