Hi There ES Peeps,
I've been planning my first e-bike build/conversion for the better part of a year (indecision KOM ). I'm getting down to the specifics finally. But I need some help with the battery pack selection. Much more specifically, I'm looking for more detailed information on commercially-available, Li-Ion battery packs with sine wave motor controllers (i.e. for hub motors) integrated directly into the pack/case. My hope is to find a battery pack/case with a controller that can be taken on and off the bike as a complete unit. The bike I plan on converting is my regular/daily commuter. It's a pretty nice bike, and I plan on continuing to use it as a conventional (unassisted) bike for recreational rides. The plan is to make it as easy as possible to switch back and forth between unassisted and pedel-assist; hopefully by simply removing the battery pack/controller combo and swapping out the rear hub motor wheel for a regular wheel.
So far I have found a couple options for packs with integrated controllers from BMS Battery:
The "Case-08" (a.k.a. Shark Pack) with 18A controller:
https://bmsbattery.com/ebike-battery/774-48v116ah-case-08-bottle-panasonic-battery-pack-battery.html
The "Bottle-09" (a.k.a. Dolphin Pack) with 20A controller:
https://bmsbattery.com/ebike-battery/681-48v10ah-bottle-09-e-bike-battery-pack-battery.html
I have found a few postings here on ES about these two packs. Mostly, it seems users are discussing the short comings of the packs' mounting plate. However, I have not found any detailed information on the controllers themselves. So onto the questions/request:
i) First, does anyone have and technical documents/specifications for the controllers? (i.e. connector types, controller capabilities)
Ii) Does anyone have personal experience using the integrated controllers with these packs
iii) Does anyone know of any other similar Li-Ion packs that have integrated controllers?
iv) Does anyone have any clever ways (i.e. homebrew methods) of combining a separate controller and a commercial bottle pack into a single unit?
For reference, here are the details of my prospective build:
- Bicycle: Spot Brand, Sprawl Model - Steel Cyclocross frame with Drop Bars (Roadie Setup)
- Motor: Q100C CST 36V350W rear hub motor, 201 RPM version with 700C wheel
https://bmsbattery.com/ebike-kit/651-q100c-cst-36v350w-32-hole-rear-driving-hub-motor-ebike-kit.html
- Battery: 48V10ah Li-Ion (13S4P) - Probably the Case-09 with integrated controller
https://bmsbattery.com/ebike-battery/680-48v116ah-bottle-09-panasonic-battery-pack-battery.html
- Controller: Hopefully battery integrated, otherwise probably the S12S 500W
https://bmsbattery.com/ebike-kit/552-s12s-500w-torque-simulation-sine-wave-controller-ebike-kit.html
- PAS/Throttle: Hopefully no throttle, PAS only
https://bmsbattery.com/ebike-parts/...sistant-sensor-with-12-pcs-magnets-parts.html
- Display: Again hopefully no display. Or I will cable-tie the display to the battery pack to act as an on/off switch
https://bmsbattery.com/ebike-kit/548-s-lcd1-e-bike-lcd-meter-ebike-kit.html
- Brake Sensor: TripWire (new) probably used at the caliper of my mechanical disc brakes
http://www.ebikes.ca/product-info/tripwire.html
Also for reference, here is my commute/riding style details:
- 40 mi round trip commute. Will probably charge battery at work between the two 20mile trips if I can't get the full 40mi from the 10ah battery pack
- I'm an athletic cyclist, so I'll be supplying all of the startup effort and still want to supply much of the power output at cruise
- Mostly flat, paved roads and trails (not much need for low-end torque)
- Will be riding in all conditions (rain, snow, ice)
- Will be swapping wheels/battery for regularly riding as much as twice per week
- Just looking to take out some of the daily fatigue from 40mi of riding (leaving something left for my mountain bike )
Thanks for your help!!!!
