Re: Grin Phase Runner / CA3 and BBSHD

Update: Juttering gone after reading in another thread to turn the phaserunner to be in pure hall sensor mode. I also moved the minimum throttle voltage to where it starts humming as suggested before and the on/off seems to be much smoother. Could you post a URL to the that thread plz. I've read th...

Re: 18650 21s15p - 3 layers of 7s (balanced separately) advice

The THICK yellow wires are the ones that carry all the current. The thin long blue one carries almost NO current. See how i did it with my pack. I just used 24mm wide 0.15 strips. Btw: The thick red main wire was soldered FIRST to the nickel strip, then the nickel strip was welded to the cells. So ...

>>>- on board charger, $100

Can you give me specs on this item please, I am interested, also do you have a 220VAC home charging solution for that bike? Or another CC/CV chargers, 0-120V 0-25A is nice.

Keep in mind bms-16 does not balance. New bms-16t does. Also have bms-8t now. Now with com. port. Ya I know people that have bought them thinking the BMS16 was a BMS like it says That is clearly shitty marketing as it should stay right straight up every ad THIS BMS DOES NOT BALANCE.

Re: Big 100 Volt 54 ah Battery build

Well you can assume resistance of wiring and BMS is same as resistance of two cells or you can calculate the exact value and sum it up to battery internal resistance. No? :D :D I’m not sure which is the best way. Or I’m not sure which is the correct way. I guess the proper way would be to calculate...

Re: Big 100 Volt 54 ah Battery build

To calculate wire resitance use any of calculators by doing a quick google search. You can also find resistance per length tables for various wire gauges. Sum both resistances. This is aproximatelly your pack internal resistance. I don't see how you are getting the need to "sum both resistances". R...

Re: Big 100 Volt 54 ah Battery build

Even though I was able to pull 230 or so amps from this, I had huge sag at full throttle and off the line. 96 or 97 volts and would sag to 84 or so Vs=I*Rp so Rp=Vs/I so (97V-84V) / 230A = 0.0565 or 56.5mOhm I don't think 56.5mOhm is all the bad for a battery pack but let's take a look at the pack ...
