When I charge the battery with the onboard charger, the battery does not charge above 87%. With the yellow quick charger, it charges until 100%.

It has the power tank. I read the log files and both batteries are doing well.

What is wrong?

"many electric motors can rev at >10000rpm". All sizes of e-motor exist. The tiny servo-micro-motor can rev at 40000rpm, and the very big nuclear submarine motor maybe 250rpm or so. Somehow size matters. The bigger the slower. Therefore I can imagine that the medium-sized Zero motor is safe at 6k rpm, probably usable at 7k and may explode at 10krpm....

The motor of my BMW i3 revs more than 11,000 rpm. That motor is bigger and stronger than the Zero motor.

Thank you, Terry.

I just bought myself a 2016 KTM 1190 Adventure (next to my Zero and 5 Honda CB750s), so my wife will divorce when I spend more €€€ for a new 2017 SR 

Is it possible to increase the max. rpm from 6,000 to 7,000? I have replaced the front sprocket for a smaller one and I occasionally need a higher speed than 135 km/h. Regards a 2015 Zero DS. If yes, how can I do that?
Many electric motors can rev at a higher rpm, even more than 10,000 rpm. So I can't imagine that the Zero motor cannot occasionally rev at a higher rpm

N'joy. Took my stock sr 2015 for a relaxing midsummer ride with my missus to day. Got 104km and 30% left. All it took was relaxed driving at app 60-70 km/h.

I did 269 km at that speed with my 2015 DS + powertank. With 11 kms left

I am considering to purchase the double and single charger. The double charger can charge through the chargeport, the single through the controller.
My question:

Is it possible to supply the single charger with a charge kabel with connectors to connect to the controller, as show here?: http://zeromanual.com/index.php/Advanced_Modifications#Charging_Through_Sevcon_Controller

I mean instead of the brown Anderson connector.

Second question:
I want to put the chargers in the rear case. What is the length of the charge cables?

In regard to connecting to the controller, the single charger has a short (20cm) DC output cable with an SB50 connector. To be able to connect it into the controller terminals you can make a DC cable using at least 6mm2 gauge wire with an SB50 on one end and suitable sized ring terminals on the other end. Rather than making a cable that is long enough to have the charger permanently connected to the controller while riding, I'd suggest you make the cable from the controller short and add a boot and cover to the SB50 connector for weatherproofing and tuck it out of the way when riding. When stopped, you can pull out the SB50, remove the cover and then connect a DC extension cable from the single charger to the short cable from the controller. While technically, yes, we could make the controller cable and the extension cable to suitable lengths, we have not tested the chargers permanently connected to the controller and so don't want to give the impression that this configuration is supported when we haven't tested it.

The standard DC fast charge cable with SBS75XBRN connector is 1 metre long (noted in the User Manual). We can make a longer cable, say 2 metres if desired. Just add a note to your order or email your requirement to support@evtricity.com.au.

I will connect the cable fixed to the controller and keep the other end of the cable with the SB50 connector under the seat (I have a quick removable seat).
I dill not always need the quick chargers, only when I am on a longer trip. When I make a longer trip, I can take the topcase with the chargers with me and connect these when I have to charge.
It would be great if you can make these ring terminals to the cable as I don't have a crimp tool. Iw ill contact you later with the details.

Great job!

What if I plug this 7.2kW charger into a 5.5kW chargepoint? I mean: this chargepoint is limited to 24Amps (not just the fuse, it tops the current at 24A). Will this work?

The 6.6+kW charger has two AC inputs set to 15A current limit per input. If the charging station only offers a maximum of 24A then you should only plug in one of the two AC inputs and the onboard charger to stay under the 24A limit.

I understand that this will limit the current as well. But if I plug in both chargers to achieve a faster charging, will it also work with a total of 24A input (and obviously also a limited power output)?
