25A Controller NOT compatible with Thin

[paxtana]

Wire nuts are not a reliable strong connection suitable for long term use in high power transportation.

FolsomRider Have you had any issues with the battery or motor since splicing the 4-pin battery connector to the new controller? I know lunacycle advises that people use an XT-90S connector (https://lunacycle.com/batteries/conn...with-pigtails/))

FolsomRider What's the downside to using wire nuts and electrical tape? I noticed you said you "Wire nuts are temporary until I can pick up some butt splice crimp connectors..". Just curious why you wouldn't just stick with the wire nuts?

[FolsomRider]

this screen and controller option should work. http://lunacycle.com/batteries/gauge...ammed-kt-lcd3/
you will need to cut the battery connector off the original controller (Sondors uses a unique aircraft 4 pin connector to the battery) and splice it on the Luna controller but it is simple. You can use butt splice crimps, Solder, or even wire nuts if you want. PM me if you need help.

[FolsomRider]

Yes it fits perfectly. The round black rubber pads in the pics are to enough leave space for the battery. It clicks in place like it would otherwise.

You will need to get the matching LCD to program the controller but it is $100 for both as a package from Luna. Works great! 20 Minute install.

Folsomrider: does the battery fit anymore so that it clicks to it place now that there is wibres behind it?

Do you have the 3party computer, does it work also?

Sondors Thin with 25amp Controller:
Pics of simple re-routing of cables. A little electric tape and voila...

No extensions or other cables needed.

Wire nuts are temporary until I can pick up some butt splice crimp connectors..

I installed my Luna 25A controller today on my wife's Sondors Thin. Easy and works great. Not sure what all the whining was about here. I am only running the stock 36V battery so I left it at 25 Amps for now. I will post installed pics shortly.

Hi guys,

I would really not recommend the 25 amp controller unless you really know what you are getting into.....

wiring is the least of your worries....

25amps is too much for the stock motor and battery unless you really understand how to use that power wisely.

Honestly i think a plug and play 25 amp controller is too much...if you cant figure out the wiring what are you gonna do when you fry your motor and have to replace it yourself?

I think 25 amp controller is really reserved for advanced users only....and those who cant accept the hassle of a bit of wiring should not even try.....

its not worth risking frying your motor....a repair you will be not be able to get past easily. If you cant wire a controller i dont know how you are going to rewind a morot or r lace a wheel.

And sondors or luna is not reponsible once you make this choice of taking on a 25 amp controller. You dont need the extra power...trust me.

Unless you are upgrading the battery pack the 25 amp controller is useless anyway.

Send in the 25 amp controller for a refund....we can do that quickly.

Just stick with the stock controller or go with a 20amp controller which is smaller and plug and play.

Not intended to be harsh at all and I appreciate the hard work. Luna is a dream compared to dealing with Chinese merchants, but all the same it's better to have realistic expectations. In my limited experience, stuff takes awhile no matter what time of year. I bought a battery in mid-Feb and it shipped without a charger, got in touch with support and 10 days later it arrived, only without a barrel connector which took another 10 days. Start to finish the order took over a month. My charger broke recently and it's more of the same, probably be down for two weeks. That's just reality so I'm going to order backups wherever I can find them.

Wow dude harsh..I am legit working 12 hour shifts trying to handle things with a staff shortage during peak season. Our being shortstaffed has got nothing to do with the low prices, it's just hard to find competent people who already know the ebike scene in and out. I guarantee if you run into a problem during January or something we can indeed support you lightning fast, when we probably won't be getting 100 emails a day.

[CraigAustin]

I agree with the earlier posters that Luna is doing its best. Just beware that selling stuff at cut-rate prices means limited support. The notion that they respond to problems and fix things "lighting fast" is just wrong. My experience is that it takes 2-3 weeks to solve anything, and that's if you press your case. If you want things to work all the time you need to order 2-3 backups for everything, that's what I'm learning. Ebikes are totally awesome but they're expensive no matter how you do it.

[Rodney64]

Yes i think you have added enough Paxtana. The main thing you have added its not plug and play.

[paxtana]

Hi guys so I can update the listing if you think the wording needs revision..
For the 25A version I have added to this line

This larger 25A controller fits if you mount it upside down, with the cables run along the top, or perhaps running wiring behind the battery, and if necessary extending some cables.

If anyone has better wording I would consider adding it. We know (most of) the connectors work, and you do not have to match the controller to the 36 potential halls combinations on the motor (which is the REAL hassle of matching a controller that's not designed for it).

I would also like to ask for any suggestions regarding the 20a version. Can you put it outside the compartment and have it work regardless of whatever perceived wiring shortfall inside of the compartment by simply routing the wires to the outside? I would assume so but would love to hear it from someone using it.

All modifications take some creative solutions. That's all a part of making changes to eBike systems. If I had a dollar for everytime I had to step back and rethink the process I'd have enough for a hell of a drunk or mega meal. So many of the new folks who've purchased inexpensive under powered bikes expect that every add on be as simple as it was to buy the bike. I'm sorry it just isn't so. Wire to short? Add wire.

Every eBike builder on modifier does themselves a disservice by not learning basic skills like soldering and wire joining.
