Witch fuse I best uses When I have Battery 30 Amp do I use 30 Amp fuse? Or 40 Amp fuse? With battery 17s and motor 4300 watt, do I use 70 A or 80 Amp fuse?

To transport the current from the battery to the controller What thickness of the cable do I best use The charts about it awg max Amp give me an indication You have power transmission awg 10 is 15Amp, multiple cables. use by Chassis wiring awg10 is 55 Amp one cable better cooling For bike use...

The old phaserunners can't, the thermistor line goes to ca. I saw in ca manual step in; limiting temperature values of Temp->ThrshTemp = 90 Deg and Temp->MaxTemp = 130 Deg we use an upper calibration temp of (90°C+130°C)/2 = 110°C, It's says not that it's's for bafang motors but maybe good...

For use with phaserunner and bafang mid motors to prevent the motor from overheating, I want the phaserunner CA to step in and limit the power. the main thing is what temperature is maximum that is sustainable for the engine? I read at Bafang 80C° and sometimes 120C°. where to best place the...

I removed the inside of the motor and with wooden hammer in the front ge starts moving down, and after a while up and down he become looser and looser after grinding the front, its already for the bin, and a lot of penetring oil, in and out and after a hour he was loose. :) The motor housing...

I don't get it out of the frame the bafang bbs02 Place it a couple of months ago when i remove the bolt I used more the 100 nm I use penetrating oil I used soft hammer, to get it out, but even that don't change anything I hammer so much that even the thread of the motor is damaged I use cowbar...

Suddenly complete shutdown. I changed battery pack. When I connect,  I saw sparks coming out the phaserunner. Home I disconnected the phaserunner , the phase connector is melted to the phaserunner.  I can't disconnected.  Inside the phaserunner I see black, see picture.  I use now only 60V...

I was making a battery pack with Samsung INR18650-35E, I was short of batteries. are not available anywhere. My supplier had them refurbished. I bought this one, there appear to be two dots on the contact points. Spot weld that were not good and this was refurbished. I contacted the supplier and...

I charge always as low as possible, sometimes 20 hours for pack the lifespam in the first example is this 2 times more then second or not 2 times from 3.6 to 4V lets say 2 times every week, lifespam 2 years and second example, one time from 3V to 4V one time every week, lifespam 4 years or not...

The question is not so clear what I mean is, I load 18650 battery to 4V (80%) Battery discharged to 3.6V then charge battery again to 4V (here I charge two times) Or is it better let the battery to go to 3V and then charge to 4V (in this example charge one time) battery live 1000 charges...

Mine back battery pack is made of alluminium that is also conductive, and only two heatshrink folie away from battery. I want made two cases, one for in the bike frame and one for back pack. 21700 cells. For Backrack I use 10P x 21S, I have made the case. Aluminium, carbon, plastic or 3D...

A case made of carbon. Is that not good and strong material for battery case?

Electric cars , they say the battery can work 10 years. Like Tesla. Li-ion battery can 500 to 1000 cycles (100%, 90% or 80% full charged)? Example drive to work 50km Battery full 100% after 50km 90% full On work, Charge again to 100% (not good I think but every body does it.) Drive to home...

Jerking when I lose throttle is gone. But now is when I start fast, full throttle, jerking. When I lose throttle then open again, jerking. When I open little bit throttle, jerk a little bit and sometimes it starts up. When I peddle hard, it's happens not. Very annoying controller. :cry:

I have a better name for the phaserunner, the jerking motor controller. I have thousands of euros worth of products at grin technolgies, but they don't get any service. They answer sorry for the long wait and then a solution that does not work or I do not receive an answer. Most problems have...
