Is there a 3rd party higher capacity battery that will fit the Rook/Colt???

Hi all friends,
I'm Susie, many many thanks to your trust and support on me and our batteries.
I'm going to take my maternity leave in the following days, for about 4 months.
Then if any friends here need batteries, can still send email to my box: [email protected], my colleague Jenny will help you proceed the order, battery quality will be the same. Don't worry.
Take care and best regards!
Susie
 
Hi Susie,

I just want to say, congratulations with your new to be baby.

I now have over 5,000 KM of riding on my battery I purchased from you on my Surface 694 Shred bike and my wife has over 4,000 KM of riding on her Rook...I’m still a huge fan of these batteries and chargers that I purchased from you...thank you so much.

Thank you! You're so nice! Best wishes to you and your wife!

Congratulations Suzie. Just to let you know my Retenton Dorado 48v 20.4A 500watt battery that I purchase from you for my 2018 Surface Colt is still working beautifully. I can easily get 50 miles on a charge using all various assist levels.

Thank you so much for your feedback!
 
oops chiming in late here - susie, welcome back and congrats, hope your fam is managing to get some sleep with the new kiddo around! all three of my aijiupower batteries are working perfectly - reckon i put ~1400 miles on one of my dorado packs and ~500 on the other dolphin-style... had to tow 100 lbs of sand up a long hill so was really glad to have the extra capacity. (also did the trip with 200 lbs of sand but that seemed a bit risky on my trailer (causing hitch to drag on my rear rack) so i started doing smaller loads!)

Hi Hewson, thanks a lot for your feedbacks! It's great our batteries satisfy you. Hope they can last long!
 
Dear all friends, we now have REENTION Dorado 21700 type battery, can make up to 36V 30AH or 48V 25AH, by Samsung 50E (5000mAh) cells. Anyone interested can contact with me.
Hereby I attach the differences of the Dorado 21700 battery and Dorado Max battery for your comparison.
This Dorado 21700 battery can bring you about or more than 93 km range. Very exciting~

Susie

I recently acquired the 48v 20.4 battery through Susie. because of the weather I only managed to get out for one ride. After 62km the battery indicator on the controller showed only 4 bars left out of 10. Looking at that it appeared that more than half of the charge was gone. However, the indicator on the battery itself still showed 3 out of 4 lights. Could it be that there is some setting on the controller where it's set to show power on a 10.3 ah battery rather than on a 20.4? I have a 2017 Rook and the Bafang DP C07.UART Electric Bike Display.

Sorry, but it's important to use a multimeter and post actual voltage readings.
Those battery "indicator" modules are 10 cent parts and not at all reliable.

I realize that, but had I even posted the readings, I don't see how that relates to my question. To reiterate: are the individual battery parameters entered and set into the controller unit, or can the Bafang DP C07.UART determine the size of the battery on its own?

I think it only needs to read the voltage and that gives it a % of charge left or it translates that into number of bars showing. but that is an interesting question - I just assumed so I hope to find out too.
Now I think I vaguely remember reading that it has to be set.

a voltage reading by multimeter can confirm the accuracy of battery and display readings.
Well, based on the manual, there is no input into the display for the ah of the battery. After a few rides it appears that the display is out of sinc with what is actually going on with the battery. After 37km the display was down to 6 (of 10) bars. At 70km it was down to 4. However, the voltage read 48.7v, which is 61% remaining capacity. After 104km, I was down to one bar and one light of four on the battery indicator. At that point my multimeter read 46.4v or 40% remaining capacity. I rode the entire time on PAS2, on rolling hilly roads. So based on that, I probably could have gone another 30km before reaching 20% of the capacity. In summary, my potential range at this time is 130km, and I rode in 6-8C temps.
