Although the schottky has a power surge loading, it is still good practice to have battery voltage fairly much aligned. How much voltage drop one see's will depend on unit temp and current drawn.

Ferro fluid use to be used and only approx. 30mls is req'd. A thread on de.forum one guy pulled over 2000w from a 250w Bafang swxk hub use don a tadpole trike and he ran it very successfully.

Personally I would parallel making sure the voltages pretty much matched (within .0.02v before connecting together. Not sure if the Orbea does any handshaking, but I would extend the discharge wiring out of the battery base/controller and in line on each battery feed place a shottky diode...

If more power/torque is needed for cargo towing then use coolant in a 250w hub and give it 30/35a, one then will have ample power.

Can anyone tell me the available parameters viewable on the screen, for instance does it have a voltage readout like the KT lcd3 ?

I use dc 6 - 80v lights F&R on my main bike wired via the battery/controller, other wise I use usb lights for my needs.

The Red discharge connection is a Deans connector, the charger port is a dc 5.5mm x 2.1mm female one. I would not use the same type connector for charge and discharge. Simply change the charge jack to one of these type below. 1x FEMALE +1x Male 2.1MM X 5.5MM DC POWER JACK PLUG for CCTV/REPAIRS...

Pleased you are now sorted and happy with the upgrade, most folks are tempted to go for the cheaper brainpower stuff but they are simply not as good or user friendly as the KT. Plus KT are so universal nearly everyone seems to sell them on Aliexpress as well as all the china.coms.

What I would say is play with speed limit % on 6 - 9, esp if the high current limit is for hill climbing. The lower the speed limit the better the torque should be for climbing.

Battery should be fine it will use the Panny GA cell, a 10a rated one though 5 -7 a max is it's mark. They are good for up to 25a continuous, check the battery specs from the seller to be sure.

Mooch rates the M35 cell from Moli as an equal to the GA, keep the current draw at 5 - 7a max for longevity/life cycle.

You will want vfr to fit it next having done most of the work.

Have you tried the self learn procedure ? There is no need to change any of the motor/hall wires. We seem to almost get this same issue nearly every month or two with users buying the cheap crappy DD kits, we had one just recently. The procedure has been explained so many time son here that it...

If it is a a three wire connection then any throttle with three wires should work, one has to make sure the wire sequence is correct so tell us the wire colours on both sides to see if you have them connected correctly. E08 is simply throttle error, so wire issue, hall sensor or a 5v issue...

If sq drive cranks they will be a standard tapered sq drive so one can use any generic tapered crank, nothing non standard about them at all. Sq drive generically replaced the old cotter pin set up we had as kids and is found on all the cheap end bikes and after market mid drive e kits.

DLG is another China brand, ES cycle testing again at 3a showed the 3000ah cell being tested was quite poor and and 100cycles over 11% capacity was lost.

When tightening spokes one needs to ensure the wheel remains true, always best to attach a cable tie to the stay and trim the tail so it touches the rim, then one can use it as a gauge for true and tensioning the spokes. I used to rely on plucking for tension but nowadays do also use a...

8a rated may mean 15/16a max current so go with 14awg, if one uses wire rating to small then it causes a current bottle neck as well as losing watts due to over heating. 15cm lengthening is nothing to worry about.

Had a Mooch on ES and found someone cycle tested the BAK N18650CK at 3a the results weren't to shabby 2.26% capacity loss after 50 cycles.

At less then £2 a cell the BAK 20A N18650CNP has to be a no brainer to try out and may well be on my to do list as soon or before spring I will be wanting a small 7 - 9ah 13s 2 or 3p in a bottle battery, it is a whole £1. 20 cheaper then the excellent molycel p26a. As has been mentioned the...
