ERider moped Help

[wheeliepete]

Let's not think about new batteries just yet, there are several options you could take. I was just pointing out that the Erider one is not great value for money. Take a few steps back, you need to find the controller and establish it's current rating.

Yes I will try to locate the controller soon. But got so many other jobs on too. So when I locate it I will let you all know what’s on it

Also what do I now do with the battery I have now

If you do buy a new battery, you could keep it and carry it in the back box fully charged. Then if you do run out anytime it will get you home without pushing.

You mean connect new battery to moped if I got one, then this one place in box beside other for a back up one, yes thats if there will be room for 2 batteries, But then I could always place it under seat or back box

Would anyone here know what this other key slot is for on right handle bar. I don't know if that's by ERider part or someone fitted it. but I don't have a key for that one either or that back brake one. But the rear brake isn't expensive well cheap

The latter, in the back box/helmet box/under seat. Until you got used to the range with a new battery, it would be an insurance against running out and pushing.

Or you could use it as a range extender, allowing occasional longer runs using both batteries. I've ridden pedelecs with up to three batteries allowing hours of run time. You now know that battery is good, just not a big enough capacity for the moped to perform as well as it could.

Looks like the throttle has been replaced on the bike at some point, the lock is part of this. As you have another switch, there is no need to use this one.

Yes I will take spare battery, with me if I go on a long trip. always comes in handy. it does seem I'm going to have to buy a new battery. to match the controller. But where to find the cheapest place I don't know. I use AliExpress. so Probably from them. But depends if there shipping is way too much, as when I bought a 24V lithium from there for my electric bike. which you guys helped me to change it from 2 x 12V SLA ones to 1 lithium, I don't remember paying shipping cost then, But think it was just over £100. then also I would have to make sure the lead to the discharge is 3 pin, and from BMS a dc jack plug

If you say you think the throttle has been replaced so that could be a throttle lock then. but what's that meter above it for. looks like maybe a mileage meter.

I also forgot to tell you guys the other day when I took moped for a short run. and it kept like cutting out missing etc. I also found that the throttle was sticking, as when I turned off key and turned back on wow bloody moped started driving on its own without me touching throttle. I nearly ended up in a hedge LOL so funny as had to jam on brakes quick

Lastly is it now ok to wrap this battery back up again with grey tape what's on it now, or do you guys need to check BMS again if not I will tape it all back up

 

[vfr400]

The display is a voltmeter to show battery voltage and the key is just a switch. Normally, you'd wire in the wire that powers the controller (ignition wire) so that the switch switches on the cotroller and the display. If you already have those functions, they're not needed on the throttle.

It's a power on/off switch/lock for the controller, the display shows battery voltage, neither would appear to be connected.
You may need access to the BMS again, so maybe a single piece of tape over the area you have cut would be a good idea.

Ok I will just replace battery lid for now

Ok guys I have now located the moped controller, it was under back of seat. not near pedals, I have uploaded a few images.


I also have another question regarding charging. my electric bike not this moped. well a couple of days ago, I accidently used my 24V lithium charger and plugged it into this moped battery dc jack plug it had obviously blew the charge light on the 24v charger IE RED charging Green Charged. I ordered another charger from eBay it arrived today But I have plugged it into the bike battery 24V I mean not moped and it has been showing red light for ages, and I know 24v battery on my electric bike is ok the original charger for electric bike had a black dc jack plug but this new charger is yellow dc jack plug, maybe that's why its not charging to green, is it possible to get a adapter which is black male and other end is to take a yellow jack plug


The Above has now been sorted


this is the one I bought from ebay but the dc jack plug is yellow unlike other one which is black, can you buy a adapter to convert yellow one to black one

There you go no wonder scooter cuts out, controller is 25a rated and trying to draw that out of a 15a max rated battery. You need to up your price for a battery, one that can supply with a bit of a head margin 30a.

No need to change it as it matters not what colour the nylon insulator is on the end of the jack plug , it won't make the charger charge differently.
How long did you connect the new one for ?

I had an idea I would have to purchase a new battery, But where from I dont know. so I need a 48V 20Ah 30Amp battery

I know the yellow female Jack plug at end of new charger seems a slight bit tighter than the black one on original charger, but I made sure the details was same on both chargers, so how comes some dc jack plugs are different colours then I put charger on my electric bike for a good 1 and a 1/2 hours I know I have not used it for a while but it shouldn't be that low or maybe it is as been standing in my flat for at least a good 2 months as not used bike so maybe I should leave it charging much longer but would it have gone that low then

would this battery be ok for moped then, as with shipping it only costs £128

thanks so much as its now just turned to green so it must have dropped down a good bit in 2 months but Im glad its gone to green now. as I will be selling electric bike once I have sorted moped, at least it will help towards a new battery for moped

I forgot to show you guys, but the 2nd time I went to sellers house, to see if I can get any joy like maybe full refund or even money towards a new battery say like £100 I would have been happy, but its quite clear he had also done someone else down on a moped, as there was this note on his door, saying persons, well in my eye persons is more than 1. he says in note He isn't a well man, and also He says at end that he lost his father recently. Well I lost my lovely sister in January age just 71 to Covid. and if he didn't want people coming to his door, well he shouldn't have sold bad goods. or at least do the decent thing and refund people, as he has brought all this on himself

 

[Nealh]

The price of the Liitokala is a bit cheap but guess China brand cells are used, at sub £2 each. Others have bought and used them so think they should be ok.
The weigh at 3.65kg is about right for 52 x 21700cells and a BMS, the important bit is the 30a continuous rating.
Don't forget you want one with the correct discharge connector unless you decide to change one of them.

Wouldn't surprise me that he is a local toe rag selling nicked stuff, it is highly likely yours is nicked as well hence the problem's with the battery and with the dodgy seller.

 

[Nealh]

Another option for the scooter is to use a lifepo4 battery pack.
Though a China sourced one will be pricey because of the extra weight.
They have about twice the life of lion cell and pack more of a punch current wise, the down size is the 30% heavier weight.

whats a lifepo4 battery pack

I was also looking at that 48V 30Ah but the weight says 5.5KG would that be ok for moped, as it says £157.51 plus £23.64 shipping which comes to £181.15 that's much cheaper than paying bloody £300 as I also bought my lithium batt for my electric bike from Aliexpress too. and that's been going for at least 3 1/2 years now

yes I will also say I want that 3 pin plug for discharge lead. but is that other lead a dc jack female plug. it says the 3pin is called 1 type. But cant see the other lead being a dc female jack plug

Regarding that person who sold me moped, he lives alone and is 70 so not too sure if he is up to selling stolen stuff. as his 1st moped he advertised on Gumtree, which was when I saw the 1st moped he had but he said it got sold 5 mins after I asked, then 3 days later he got in touch and said he has another moped but its £50 more than red one. I'm glad I didn't buy the red one anyway as it was some foreign name cant think now.

so is it ok now to order that. 48v. 30Ah. 30a. Batterie. Or the 20Ah. One as I don’t mind paying a bit extra for the 30Ah one if it will be ok

The meter on your 24v bike says that the battery is fully charged. If your're charging with the bike and meter switched on, the charger probaly won't switch to green because it will still be supplying power . Try switching the bike and the meter off.
