Can I get a better charger from a different company?

[dmark]

I am specifically looking for the highest A possible for the Ariel Rider D-class.
It is offered with only a 2A charger.
Thanks.

The Grin Tech Cycle Satiator Programmable Electric Bike Battery Charger is arguably one of the best chargers for ebikes as it is programable to set a lot of variables such as fast charging amps and charge percentage into the settings. It can charge up to 8Amps but I wouldnt recommend going above 5Amps if youd like to prolong your battery life. You may need to get an extra charger adapter depending on what type of charger input the Ariel Rider D-class has.

Like Ki11a already posted I got the Grin for my Sondors, the reason you can keep adapting it if you upgrade your controller or battery or Ebike.
For me that one is the best and Grin knows their stuff.

Is there a reason why all those links are german?

 

[ki11a]

Yeah weird, it changed languages on me on my phone...

Would this charger work for my Espin Sport? I have attached a picture of the back of the Sport charger...

Yes it should.. Just match the connector / plug as it is an option.

Do you have one of these?
I'm curious if and then how long it stays on after reaching 54.6V to top off the battery and allow for balancing as in the charging curve diagram.

t1-t2?

@Ebiker33
I'd ask the same using the Satiator.

Thanks GRocket!

 

[Gionnirocket]

yeah I do have two of these actually, and I recommended to my friends and they're happy with it.

Not sure what you mean by balancing, but it does charge up fast (at max rate, my in my case, 4A) up to 80% or 90%, and slows the charging rate down just to top up the last 10%.

I think all chargers are designed like that though?

Well according to the graph from the product page the charging rate should be the same up to 54.6V and then the current should drop off. This is the accepted method for charging Lithium ion. CC-CV.
How are determining 80 - 90%?
Have you ever monitored Voltage throughout the process?

 

[Taylor57]

I just bought the Smart 56.4 from Aliexpress. 61 total includes shipping. Will advise when it shows up.

 

[Taylor57]

You mean 54.6V?

Yes, 54.6

I have voltmeter on my bike, so I can keep my display on while I'm charging. I can see the voltage going up while charging.

This is purely from my observation, but I can see the voltage raising very high until it hits close to max.. and the charging definitely takes a lot longer for the last 1V or 1.5V.

There are numbers of occasions where I could charge for shorter amount of time, and it charges up quite a bit if the battery is low. However, if the battery is close to full or still have some Juice left, the charging definitely takes long.

So no, I have no done any scientific or objective analysis, this is purely my observations.

I have a Sport and an XP. The XP has a voltmeter which is awesome for giving you a fairly accurate estimate of how much battery power you have and how much to charge, while the Sport does not and is a crapshoot based on the amount of bars you have left. I'm just curious why Espin wouldn't have included the voltmeter feature/function. It couldn't cost much more to add at production...

Thanks T'
1 to 1.5v would be approximately the last 5 to 8%... That's probably better than the base chargers that come with the battery but I was thinking it would be 1 - 2%
Anywho... I'm just spinning the brain electrons trying to stay out of trouble
