Loose connection seems like a possibility, you'd had a look and no chance there's a bare wire, corroded wire or bad connector around where the battery connects?

I wanted to update everyone properly on my experience on the literally first ride of the Dorado 21700 25ah battery. It arrived less than 24hrs before my planned trip so other than my son taking a trip to the mailbox we literally charged this battery and set out on a multiday trip fingers...

I can confirm the process was very easy! *** EDIT *** SEE MY LONGER POST TRIP COMMENTS NEXT POST DOWN *** I got back from my trip. I will post a full review shortly but 1st impressions after the ride are all positive! We rode 102km the first day on PAS 4 (NCM Moscow) and I am a heavy rider...

They don't have an Aliexpress site (I asked), but Alibaba is linked to Aliexpress (you will use your Aliexpress login for Alibaba). The way it works is either send an inquiry via Alibaba (Dorado 25ah) or I found it easier to just email Jenny at ([email protected]) and ask for a fresh price...

It has been mentioned in a few threads here but Reention is producing a new case for their Dorado series of batteries that allow 21700 cells to be used instead of 18650. This increases the max capacity of that battery to 25ah using Samsung 50E cells (@48v). The battery is available in 36v, 48v...

To charge just one group of cells you need to think of your 48v battery pack as a group of 13 small 4.2v batteries wired in series. The balance lines all come from the interconnection point of each of the 13 groups. You can simply send 4.2v down the correct pair of balance wires to charge a...

But then my water always tastes like farts ;)

Reention is just a battery manufacturer, they don't make actual bikes (or controllers/displays). They made your battery basically Can you take some more pics of your bike and/or identify a few things: 1) Bike mfr (some side pics and pics of any labels on the bike) 2) There should be a...

For my battery I was really hoping it was something simple like that. Not the case though, tried to fuses and checked the wires, in my case I was sure it wasn't a loose wire or fuse though as when I plug in the charger the BMS shuts down entirely for a few minutes before coming back to life, but...

I am repairing a Dorado battery myself at the moment similar symptoms. Doesn't charge (light stays green) but does discharge properly. I have a new BMS coming for mine and via other batteries and chargers I've eliminated the obvious (fuses, bad chargers, bad connectors). I can say I have 2 wires...

To see your battery pack nose dive in minutes from ~54v to 49v suggests a problem with the cells to me. Is it by any chance a square shrink wrapped battery pack purchased from Aliexpress or eBay, etc? I am wondering if someone sold you a battery pack advertised as cheap and with good specs and...

My son's bike is in that state now. Just 1 key. We have a new bracket and set of keys coming for it :-)

Found something even better? https://www.aventon.com/products/replacement-key-for-e-bike-battery?variant=39825958011075 Pick the Pace 500 Reention edition and enter the number from your lock. They should be able to cut you one.

Number for the key should be on the lock. But finding blanks is tricky and then someone who knows how to decode the numbers is another thing. If the battery is off the bike and assuming it's not a Prague or folding bike, this is the part I'd recommend getting...

Yeah I'd bike by you 10 times before I ever noticed your leg, you just look like every other rider, even in your pic. Bike with a pant leg and nobody will even look twice.

Great stuff! Never too late to get out an enjoy yourself! You're going to love ebiking.

Yeah I got one myself, lol.

My feeling is no it's not done for longevity. I have a feeling that brand new cells will stay at 54.6v (13 * 4.2v) after charge but don't need to be in the world long before they no longer keep at the full 4.2v but start to go down. My existing batteries are around 4.16v per cell and I'm...

I have several batteries and we "name" them to keep track of which one is which

I don't know the weight but @Jenny Mao probably will, she sold it to me and packed it herself, lol. She works for Aijiu and is a member here. If Jenny doesn't I'll be sure to weigh it on arrival and post it.
