Is there a draw tester available for LiOn batteries similar to a draw tester for lead acid car batteries?

Just got a new G020 Bafang front hub motor from Ali Express to replace my old SWX02. I was planning on just swapping the guts from the new motor to the old but the casing on the new is thinner than the old. The new one is 48V 500W like the old one. I saw something about this being a new model...

Thanks

I checked the red to black wires and did not get 5 volts.

In BC the law says an ebike can have a motor with a maximum of 500 watts. If my controller says 500 watts, then I think I'm legal. I'm an old man. I don't drive hard or fast. Only use it for short rides and picking up groceries. Trike has loads of power for me. Cornering is a little weird but I...

That's what it says on the controller. I think it's 750 peak watts…? Misleading marketing says 750 watts.

Thank you. Cheers!

Thank you. Cheers!

I have a new-to-me BPM R-750 trike. The model is 750 and the literature says its a 750 watt motor. My controller is rated at 500 watts. I don't see any markings on the motor itself. So do I have a 750 watt motor or a 500 watt motor? Cheers.

Are you thinking that the voltage from the controller is too low? Are the values you mentioned a minimum? New controller is on its way. So is a new display. Like I said, I like spare parts. It will take some time to get the parts from Amazon but I will update you after I install the new one. Cheers!

I agree, I do deserve a new bike. Should I send you my address for the delivery?

I'm getting a little over 2.2 volts at the controller when I power up the display. ? I will go ahead and jump the display connector now. I've bypassed the display but not sure I did it properly. I jumped the red and blue and with the connector connected, the display turned on but I still didn't...

I'll buy a new one if you finance it.

Does napa rebuild them or sell them or just recycle them?

The one on the left is like mine. Reseated the round connector multiple times. Reseated the 5 wire connector. The temp icon does not change. Speed does not show when I spin the wheel. This bike uses pedal assist. The motor wheel rotated both ways with power on and off. I went through all the...

Thanks for the info. I will check this out.

Thanks for the reply. It has a brake indicator that worked before.

The brake icon is not on and does not come on when pulling the brake levers.

I will remember that in the future. Thank you. That is the same display that I have. The walk assist does nothing.
