Alright, so the batteries finally arrived (thanks Tumich!), and I'm ready to start figuring out everything else. (150) of his LG MJ1 - 3500mAh/10A 18650 cells just arrived.
I want to use the Q128C-135mm 500W CST with my road bike to help me average 30 mph on my commute. I want to build something similar to Chas58's "25^3," but more powerful. (I'm an experienced cyclist and will be peddling full bore, on a road bike, in a tuck, etc. I'm already accustomed to high speed, 40 mph+ descents, and I average in the low- to mid-twenties on my current commute, so I know what I'm getting into as far as the speeds are concerned.)
Based on the models, I'm thinking to run the 328RPM / 36V shred of the Q128C @ 48V, but I do have a nagging concern that 48V might not be the right voltage point. Most of the time I plan to ask for 250W and 500W, with possibly 750W peak, out of the Q128. At 48V, that's about 5A, 10A, and 15A, respectively, for those power levels. Even 48V isn't the best voltage point, I do think that it's fairly close.
I'm really confused about controllers and would appreciate some help here. Would you all point me to what I want? Here's what BMSbattery.com has:
--S12SH 800W 40A Sine Wave Controller with Light Output
--S12SN 72V1KW 40A Torque Simulation Sine Wave Controller
--S12SN 1000W 40A Torque Simulation Sine Wave Controller
--S12SH 800W 35A Torque Simulation Sine Wave Controller
--S12S 500W Torque Simulation Sine Wave Controller
--S12P 750W Torque Simulation Square Wave Controller
--S09P 500W Torque Simulation Square Wave Controller
I "think" that the S09P meets my needs, or at least pretty darn close, since the ~14A throughput that it does for 500W @36V is really close to the 15A peak for 750W @48V that I'm interested in.
I'd like to preserve the possibility of adding Cycle Analyst v3 at some point.
As far as display/interface, I'm leaning towards the S-LCD3 or S-LCD6, mostly because of the remote buttons, but here's what BMSBattery offers. Should I get the 72V version of the S-LCD3 in case I end up at 14S/52V or 15S/56V?
--S-LCD6 LCD Meter for S-Series Controllers
--S-LCD5 LCD Meter for S-Series Controlers
--S-LCD3 LCD Meter for S-Series Controlers
--72V S-LCD3 LCD Meter for S-Series Controlers
So what else do I need? I'm thinking:
--A Pair of EBike Torque Arm
--HWBS - Hidden Wire Brake Sensor 1pcs Two of these, of course, right, one for front and one for back?
--Ten poles PAS--Pulse Padel Assistant Sensor -- I am very confused about which of these sensors to use. There's also the Dual Hall Sensor 12 Signals Easy Assembling PAS
--Copy Wire for S Series Display Meter -- to set up a hot spare controller
--Thumb Level Throttle without Handle
I'm a year-round, all-weather (hot/cold, rain, snow) commuter, and reliability is a huge issue. I do plan on buying two of everything, so that I have hot spares. Is there anything that I should buy three of?
And I'm not married to buying from BMSBattery.com. I know that they don't have the best reputation, but they seem to be the only source for the Q128-C, and I thought that it would be easier to get everything from one place. I'm happy to hear suggestions of products from other sellers if they're superior. I hope not to spend an arm and a leg on shipping, though.
Thanks in advance.
