Sorry is it an LG/Samsung/Panasonic and what amp/capacity?
View attachment 125804

The vid guy says the 21700 5.8 A 21700 cell yielding 16% more juice overall and is newer chemistry. 🤔

Yet, I see a Samsung 8.6A out there. Wondering how our new our 21700 cells battery would stack up (given same motor Voltage and battery configuration) and if it's a little hype on his end.

I know it's always risky asking this type of question, but someone has to be brave enough to ask the "dumb" questions...just for improved learning.đź‘Š

Follow up.
Looks that would yield 5.8A as well.

I’m very interested in hearing the answers to this.

Any more details on this? Are they producing this yet? Photos and kg?

The only response I received was regarding the frame. Deliveries of frames and cases are expected to begin in late October. I don't know the price yet.

When I disassembled the housing of the 720W battery, I was disappointed. The battery was packed with blue shrink wrap. I was sorry to tear the film, because the battery was made very well. The seller claims that the battery is assembled on Samsung. We can assume that the capacity is 5000mah
 
Hello. I got a BEST PRO, but I don't know how to change the motor voltage from 36 to 48V. Does anyone know?

You need to use the right firmware for this.
I’m not sure I’ve seen the firmware in the list for 48v?
I did it - from 36 to 43 - with besst , not besst pro, and it’s easy!

Dropper insertion seems generous on this XL. But the charge port could pose a potential problem. But I'll grab a 210 one up dropper this weekend.

Your dropper won't get past the top screw on the charge port. That said, by my calculations for your XL frame, your seatpost insert length should be 324mm. Enough to swallow whole your 210 Oneup post.

I have an L size frame. I relocated the seat tube's charging post to the motor cover and shaved the inside of the frame to make it compatible with BIKEYORK 213mm.

Given how delicate the motor cover is and how many people have already broken them do you think that is a good idea?
 
i think 47V its better option because it is less stress for the battery as in less AMP require if we compare it to 36V if the motor out its the same between 36v Vs 47v. Less amp equal to less heat equal longer life,

Since the 36v motor is designed and wired for 36v you are not going to have more heat. Fewer amps yes and potentially lighter but they are probably all wired for 36v for economy of scale.

What i mean its the battery not the wires , on 36v high amp, wire don't make much difference but battery make alot of different in high amp Vs low

47v? there's no Bafang motor with 47v version :)

I broke it once and repaired it, but there's just a charging socket, so it doesn't bother me. The cover was badly cracked and the pieces could not be recovered, so I lined the large gap with Gorilla tape and molded it with silicone on the surface.

But Bafang don't share 48v firmware version. I asked Linda but nothing till now, although they sell 48v motor and 48v battery package.

Arround 2.250 mm for 27.5 x 2.6. I run 2.100 mm, giving a little tailwind on max speed, but still withing legal limits (25 kmh + 10% max)

how did you set the wheel size? The option is greyed out on my DP C244 display. In the Bafang Go+ app I can see the wheel diameter and perimeter in "vehicle information" but can't seem to change it anywhere there either

Just to make sure all the details are correct ...

I didn't think the 244 had bluetooth ? Only the 245? and only the 245 v3 has 5.1 so can connect to Go+ not just Go ?
