I've been searching the board but haven't found an easy answer for my problem.
There was a "dealer" in town but he wasn't very knowledgeable, which was why I purchased from Golden Motor directly. I also have received no replies from Golden Motor regarding my email requests to them.
I purchased a Magic Pie motor(Internal Controller) with the 36v frog battery.
(Had I know the differences I would have chosen an external controller.)
The battery charger always shows full charge/disconnected.
The battery is draining but not recharging when plugged into the charger.
The green charger LED dims a little and I can hear a click when it first gets plugged in but nothing else.
I've even tried to leave the charger plugged in overnight but still no charge.
I've installed the motor and driven it with the battery over ten miles and the LED indicator on the battery has dropped from two green and one red to one green and one red. The throttle used to have the red, yellow, green LEDs lit, now it only has the red and yellow LEDs lit.
This last weekend I took the bike out and the motor speed has diminished dramatically, is this normal because of the low battery or should I be concerned about something else?
-
It sounds like your battery is not charging at all..usually when you start the charger, you hear the first click and green led, and then the green led turns red......could be a problem with the BMS in the battery......
Worst case you could temporarily fix it by charging through the discharge lead....but not recommended...
Your battery is getting flatter and flatter. so soon it won't work on the bike at all, this is why the speed is diminishing...
-
I was thinking the motor speed degradation might just be the draining battery. Because I'm not really familiar with this motor, thought it might be better to mention everything I noticed.
I suspected either a problem in the charger or battery, I was hoping it was the charger.
This is a new purchase, How do I get the problem diagnosed and fixed?
-
Hi Marc, it might just be as simple as setting the voltage switch on the charger (if it has one) to match your mains supply voltage.
There might be a simple slide switch like this:
(https://arhservices.co.uk/GoldenMotorCanada/ChargerSwitch015.jpg)
If your charger is fitted with one, set it to the 110V setting (if necessary) by using a small screwdriver or cocktail stick etc. to slide it.
Let us know if this was the problem.

I wish it was, I checked it first, this is a simple charger, there is no visible switch, not even an on/off toggle.
I'm assuming it auto-switches.
-
The 24 and 36 volt chargers are automatic 115 or 230 volt. They do not have a switch. There is only one LED that is green when its charged and red when its charging. Do you have a meter? If not, you can buy them fairly cheap. I would suggest putting a meter on the output red and black cables coming from the battery. See what the actual voltage is. Then plug it into the charger and see if the voltage goes up at all. I suspect it will not. If it does not then it is definitely the charger. What country are you in?

Curious as to what dealer this was. For you to figure out he was not knowledgeable that means you at least were able to contact him. Believe me I am learning as I go along as well, but at least I am very accessable and put effort into resolving issues.

Call me a weirdo, but even try plugging it into a different power point on the other side of the house
I say this because the same charger (I have) does not work in my garage!!!!! Lol I put it down to some kind of field interference.
Anyways, try that lol hope its as easy as that!! Otherwise, check inside I think I remember there being a fuse inside, perhaps it has died or faulted in transit. Its worth a look
-
I'm in California, USoA. Not very knowledgeable as in didn't know much about the product line beyond his interest in selling to me, and unable to answer any of my questions regarding the motors, controllers or batteries.
I was directed to the Golden Motor website and told to contact Golden Motor directly to get my questions answered. Then, because this was purchased through Golden Motor, the dealer wasn't able to help me figure out what component is failing.
(I brought the charger in to see if it worked on a different, same model, battery, but he didn't have any in stock.)
The recharger functions the same regardless of what outlet is used. I checked the fuse, it looks good.
I'll meter it when I locate my meter, soon hopefully, I moved recently and still can't find where I've placed all my tools. I've been looking for days now, it might be in my storage unit.
-
Mark, where in CA?
I am in Ventura,
I have a 36V charger and a 48V charger.
-
I'm located in Sacramento.
I tested the battery and the charger with a meter, no change with the battery's voltage.
I think I can hear a thermal switch click in the charger when it is plugged into the outlet.
I'm curious about what the charger output for a 36 battery is supposed to be.
This one is 29.4 volts
-
Marc, if you're only getting 29.4V it sounds like you may have a charger for a 24V pack, as the charger for the 36V packs should have a 42V output.
Have a good look at the charger and see if there is an output voltage marked on it like the 54.6VDC on this 48V charger:
(https://arhservices.co.uk/GoldenMotorCanada/GM010.jpg)
The charging voltage for the standard Lithium Manganese packs are as follows:
Chargers for 48V packs are usually marked 54.6V
Chargers for 36V packs are usually marked 42V
Chargers for 24V packs are usually marked 29.4V
I seem to recall Gary mentioning that the LiFePO4 packs use the same chargers.

It appears the problem is that I was sent a 24 volt charger.
-
Marck, send an email to tom@goldenmotor.com and briefly explain you have been sent the wrong charger. Include your order details and a copy of that photo, and hopefully he will organise to send you the correct charger for your 36V pack.
Please let us know what happens.

It's been almost a week and I haven't heard a reply back from anyone.
Would it be better to go through PayPal and request a refund through them? So I can reorder the charger through someone more reliable?
-
Hey Mark,
I think I am having a similar problem, but I'm not sure it is the charger... what is the status of your situation?

I am just wondering if your battery is marked with the voltage as well. Are you sure its a 36 volt battery?

Hi Guys are these ouput voltages on chargers min ? or max ? or +/- % ? or are they subject to Magic ?
Thank You !

The voltages stated are the pre-set maximum charge voltage, and I would expect the actual output to be within ±0.1V of the stated figures.

Thanks for that !
I wonder how the one I got even from day 1 only went up to 53.8v Ihmmmmm :-\

Was it connected to a GM battery?
-
Hi Mm and all !
at the time only to ouput of charger (RCA cut down centre pin ) plug ...OK ! may be something there ! but battery (GM 48v 12 A only ever manged two thirds or the distance of SLA's 4 x12v 12 A .
( run on both batteris ) more wieght !... so they were only connected for emergency to go to ( jail do not collect 200 pounds )
home directly . (Or Pedal ! )
(charged every night all batteries )(GM pack only lit two led's on GM thumb controller ...SLA's all)
Pedal 100 kgs ebike in tropics is really hard work !
Many thanks
John L
at the moment battery is back with dealer last week ( he had a few more sets there open up for problems ) same pack 48v 12amp ....Uhmmmmmm !
-
Hi all
recieved email today from dealer ! some answer you back !
and the good news about 48v 12A battery pack dealer would like 385$ to change internals to 48v 8A....
What do any of you think about that (P.S. thats on promotion )
Might be cheaper to run it on DURACEL's
and I could just buy them as I go ! pop into shop .gas staition supermarket or even 7/11
Many thanks

Alan
This may not actually be true. When receiving my first shipment of batteries that were lifepo4 and lithium I noticed the chargers looked identical but some of the charger boxes were marked LT for lifepo4. I asked china if there was any difference and they of course said "they are all the same, do not woory". Now recently they have told me they are different. It would seem the first answer was an aswer of convenience, not fact.

Why on earth do you want to change the battery from 12 to 8Ah? You will only have 20A max continuous output and 30A peak max let alone less range.
Perhaps you may be better off with Duracell after all
-
Hi Monkeymagic and all
Well the GM dealer thinks it's a good idea ! to go from 12A to 8A ::) as I purchased the pack from him .
Think I better try get dealer to send it to me back (but it might get lost now in the post )
maybe the service charge might be 385$ plus postage ::)
This get as good as Garmin here got Offical Garmin to put new lithium batt in they broke the board no sound anymore and charge me 50$ and refused to repir (garmin is which country ) for the Privilege as they say now anything more than six months old is obsolete and not worth repairing.

-
Surprisingly I find it extremely difficult to believe a dealer would suggest changing a 12Ah pack to an 8Ah, I won't even ask about what battery management is supposed to replace the original.
Plus the fact the 48v packs are tack bound by 3, it would be a complete mess if you wanted to do this.
Which dealer are you buying from? You seem to buy alot of broken stuff ???
-
Hi Monkeymagic and all
well over 2 years one dealer
6 Hub motors 2 types
5 cruise controllers
1 x 48v 12 A battery pack
1 x charger for that battery

3 disc
3 disc brake calipers
2 sets brake levers
2 x cruise / light switches
2 x the other swich cruise on/off / horn
and I forget the rest !
not bad from private customer (Gary would have loved me )$$$$$$
look on GM website for s.e. asia distrubutor.
Seen many strange things with motors motor cable lenght from 2000mm to 450mm motors in alloy casings around two differnt ways.......

speed is fine but !!!!! exceleration !!! multi drives and quiet and (make out your pedaling leaves alot of them open mouthed at traffic lights. )
They look a bionic man lol lol lol
i have seen tandam e bikes but none dual drives Schwinn the red cruiser one looks nice I keep looking at it in the bicycle shop but no shocks ! my arse likes abit of comfort these days even eith Gel seat covers !
