L1019 to JST & Bullet plugs?

[CMo44]

So, I got a ezee hub motor from Grin that comes with an L1019 on it. I'm trying to connect it to an old ebikeling controller that uses 3x phase (green, yellow, blue) bullet connectors in conjunction with a 5-pin block JST for motor connection (I believe it's the same as this one: Shop eBikeling's 36V 500W Brushless Controller with LED/LCD - Precision & Performance!).

What is the easiest or most logical way to connect these? I only need the basic motor to controller connection for this (no regen, reverse, cycle analyst etc). Just whichever makes the motor turn and that's it. Seems the multiple thin wires on the controller JST will be a pain to cut and re-terminate. Should I cut the L1019 off of the motor and convert somehow from that end?

I bought Grin's adapter to JST thinking it was what I needed, but of course it doesn't match (L10-Controller to Anderson+JST Motor Adapter).

Depends on the size of the bullets, but usually bullets can handle higher amps than L1019. L1019 is probably more waterproof than JST. So depends on your usage. I routinely run a 750w motor at 2850w and it only rains here like once a year, so I know what I'd pick.

When I get heating or continuity problems from a motor plug, I swap in Anderson PP75 phase plugs and a JST-SM 5 or 6 pin connector. It isn't elegant, but it never makes me fix it later.

Thanks to both of you who replied! Just a little queasy about chopping off a L1019 off of a brand new motor for some reason.

So I assume the colors just match up to the new connectors when I do cut off the L1019?
Like I said the controller has the 5-pin (in 6 holes, middle top is empty) white JST* as well as 3 bullets for motor connection.
(*is this actually a "Molex/Spade" connector and not JST? That's what the grin/ebikes .ca connectors page seems to point towards)


I'd prefer to just replace one end to match the other (aka if I cut off the L1019, I'd prefer if possible to match what's already on the controller). But, maybe I'm just being lazy about it.
If you've had success with the Anderson PP75 and JST-SM 5/6 maybe I'll go that way. Now I just need to find those connectors!



And @lnanek, the bullets are decent size (as shown in the image). They're a thicker wire unlike what's going to the JST's and other block connectors. However, this project is lower speed/higher torque and isn't going to run crazy power. The controller and battery are from my 500w/36v e-bike (and I got spares of each trying to diagnose a problem that turned out to not be related to these parts).

You'd think so. You can even start with that assumption. But there's no reason that any of the wire colors have to correspond. Ultimately it's big y/g/b wires to each other in no specific pattern, small y/g/b wires to each other in no specific pattern, red to +5V, black to GND. Maybe you luck out and the colors match up.

I would cut that L1019 plug off the adapter that you already bought and wire that to the controller. Grin has the wiring diagram for the L10 plug on their website.
I pull up to 1400 watts at relatively short periods through it on a 52v system and have had no problems.

Oooh that's a good idea. So basically snip off the JST ends of that adapter and wire it (the remaining cable with to the female L10) to the controller so that female L10 is now the controller motor connection? Thus I'll have male L10 at the motor and female L10 at the controller without having to search for and re crimp/splice cables! Amazing! Thanks @gromike !
