48V10Ah Case-08 Frame Bottle Battery Pack with controller

[roscop13]

Dear electrified crowd,

-Woud you recommand this 48v battery with 18A controller? any feedback?

-Also, I'm kind of frustrated that they are using 2500mAh batteries in that pack, is there any way to buy a case like that with integrated controller and a BMS but without the battery? (so I could use Sanyo 3500mAh batteries)

-What motor would you recommand to go with it to ride at a top speed of 35km/h or faster?


Thanks for your help!

You didn't look very hard, both the case and the controller are available in the "Ebike parts" and the "Controller sections. @ BMS B.
Not much point in using a large motor w/ an 18 Amp controller. The Q100H and the Q128 would be suitable.
Profile please.

thanks for your answer,

Maybe for my first bike it is better to take a prebuilt battery pack as I found the same battery pack exist with better PANASONIC cells, do you think that is is a good choice for +100$ ?

I was thinkng of using it with q100h 260 model overvolted @48v, does it make sense to reach the 35km/h with 700c wheels?

thanks for your feedback

The experts over at Pedelecs UK have verified that the Panasonic cells used in BMS Battery's batteries are genuine and they feel they are worth the extra money.
According to the Simulator @ Ebikes CA
Q100H (260) on 48V in 700cc wheel= 39 Kph.
This combo is ok on moderate hills, but not advised for long, steep hills.

Where are you located ?

I contacted D8VEH @ Pedalecs and he said that the Q100H might overheat in some conditions with this configuration detailed before:
"The Q100H packs a punch at 48v, but it's still a small motor. The 260 rpm will become 328 rpm at 48v, which is about 26 mph maximum, though power will drop rapidly after about 23 mph. The problem is that all the time it's below about 15 mph, it'll be drawing maximum current, which can make the controller get very hot as well as the motor itself."

Then D8VEH kindly adviced me to go with the following configuration, using a bottle 09 as it has a on/off button and a USB and a Q128C 48v 328 version:

-I live in France, I will mount it on a a vintage 70's race bike and i'm 75kg. Using the simulator I think (not sure that I'm using it right) I've found 36.7Km/h top speed, is that correct?
-With this Q128c do you share D8VEH thoughts that it will be a better choice less chance overheating and better for moderate hills?

Thank you for your good feedback

Roscop13, did you ever go through with the build? How did it work out?

I'm hoping to bump this year-old thread. I am looking at a very similar build for my first ebike project. I'm particularly interested in Li-Ion battery packs that have integrated controllers. I'm an avid (non-assisted) cyclist, so I'm planning on attaching this kit to my existing cyclocross bike. I'd like to make swapping between e-assisted and non-electric setups as easy as possible.

So far, the only source I've seen for these types of battery bottles/packs with integrated controllers has been BMS Battery. Namely, the "08" and "09" bottle cases mentioned in this thread. My main question is does anyone have more specs on these bottle integrated controllers? Ideally, I'd like to look at the connectors to see if their consistent with other non-integrated controllers (i.e. the S12S) which I would probably use otherwise.

For reference, here's my prospective build:
Battery - 48V11.6Ah Bottle-09 - https://bmsbattery.com/ebike-battery/774-48v116ah-case-08-bottle-panasonic-battery-pack-battery.html
Motor - Q100C Rear, 201RPM, Laced to 700c rim - https://bmsbattery.com/ebike-kit/651-q100c-cst-36v350w-32-hole-rear-driving-hub-motor-ebike-kit.html
- No throttle, PAS only
- No Cycle Analyst
- Ideally no display (though I may just attach it close to the controller for easy removal)
- Inline brake sensor

I'm not particularly concerned with top-end speed. I plan on doing most of the low-end-torque, low-speed work with my legs. I'm mainly just looking to for something to take the edge off my ~40mile round trip commute while being relatively stealth and easy to take on/off.

Finally, if anyone knows if there are any other distributors who service the United States that have battery packs with controllers, please let me know. I am a bit hesitant to go with BMS after reading many conflicting positive and negative experience.
