Help! New Swytch Max kit that loses most of its power after 15km on a normal ride

[xla99]

Hi there,

I've an issue with my kit and I gave up with the Swytch Support, which is amazingly inefficient. I can't believe it, they are close to psychological harassment with their techs almost as bad as their AI agents asking me over and over again the same things without answering my questions.

My wife bought a Max kit in September (no throttle installed). That was working fine the first weeks, and it suddenly started to lose power after 15km. I did all the tests asked by the support, rechecked the câbles, the wheels, reset the controller and everything is fine.

A typical ride now looks like that :

1. Full charge, 10km to work, arrive with 4 power bars remaining (60% power limit setting with a 3/5 PAS)
2. On the way back, after 5km, it suddenly drops to 1 power bar, the motor runs on & off and she may end the trip without assistance
3. The battery is fully recharged in the evening and it's the same the next day

That ride is not steep, no wind, good weather, 5 degrees. We have a friend with the same kit that does the same ride. He has no problems to come back, with 2 power bars remaining at the end of the day.

I couldn't even get an answer from Swytch about if that's a normal behavior for a new kit or if it's an issue. So I ask it here, do you think that's an issue and if you do, what could be the root-cause ? The controller and/or the battery ?

For now, we bought an expensive Swytch charger and she charges her battery at the office but I would like to understand that issue and maybe fix it.

Thanks.

No, they are very efficient at their main objective: to avoid giving you any support.

I'm pretty sure that it's a battery issue. It's probably just out of balance, but it could be defective. How many miles has it done?

If you have any technical ability, you can open up the battery to check various things. If you haven't, then the only thing you can try is to leave it on charge for several hours after you get the green light to see if it improves.

If you can, measure the battery's voltage immediately after you take it off the charger. Any less than say 41.2v would mean that it needs some attention.

Hi Saneagle,

It has almost no mileage. My wife started to use in December @+-50 miles a week. It worked well the two first weeks and started to bug last week.

I haven't any technical abilities in that field but I'll try to keep it charged the full night and check the volage with a friend's voltmeter.

Thanks for the tips.
