Re: KT motor controllers -- Flexible OpenSource firmware for BMSBattery S/Kunteng KT motor controllers (0.25kW up to 5kW

Question to the expert of S06S... I use the S06S "boosted" with the original software and I have already a big issue with a overcharging of the battery during speed regulation with regenerating braking. The BMS has cut the battery charge and the regenerative braking have produce a pic voltage in the...

Re: My Sun Trip Bike, Back to Back Tandem Trike with Rowing Generator, Pedals, +Solar

What I've learned is that for sure the most important strategy for covering ground like those at the front is just to be on the bike for as many hours as possible between 7am - 9pm when you are allowed to ride.... If you don't get packed up from camping and breakfast until like 9-10am, and you take...

Re: My Sun Trip Bike, Back to Back Tandem Trike with Rowing Generator, Pedals, +Solar

According to previous Suntrip, the best can ride a arround 200-320km (120-200miles) per day. So the first group will ride the 12000-14000 km (7500-8750miles) in arround 40-50 days. For the majority, this will take more than 2-3 months.

Just, just in time! :roll:
Have a nice trip to France...

Re: KT motor controllers -- Flexible OpenSource firmware for BMSBattery S/Kunteng KT motor controllers (0.25kW up to 5kW

So, do you think I can be face to magic smoke with my S06S boosted to (60V 55A) ~3KW* used with a direct drive motor? Maybe you should try with a new one before testing with your custom version. Ok, it’s safer. I order some new S06S and LCD3. It will just take some time to receive them. Do you make...

Re: KT motor controllers -- Flexible OpenSource firmware for BMSBattery S/Kunteng KT motor controllers (0.25kW up to 5kW

A very interesting, great open topic also quite interesting for updating my “old” S06S. I like this controller but I’m not using it so much du to some programming features. - motor efficiency with the direct drive motor (not so good at low power) - no e-brake function though the normal break contact...

Nice and crazy project again. I wish to the customer :wink: a lot of fun with this incredible e-bike. 8)

PS: I was also really impressed by the performance of this polymer cable with breaking at 1150 Mpa! :shock:

Re: Project Interceptor, oil cooled Q100H@55V, in-frame batt

Re: Cycle Analyst V3 preview and first beta release

@teklektik, Good idea, it’s possible to developed but I brought a CA V3 and a Thun torque sensor to remove a home made PAS electronic card I made… 8) i don't use a torque sensor, and it wouldn't work well with a mid drive setup, but when i wanted to buy one for my other ride i thought that starting ...

Thanks, unfortunately this confirmed my meaning. I can't understand that Justin forget this function. :oops: Is there a incompatibility with other function ?

Re: Cycle Analyst V3 preview and first beta release

Just a question to the CA expert... I have a CA V3 B19 connected to a Thun torque sensor. I try to have assistance for starting from 0 speed by pushing on the left pedale. I read the CA document but I doesn't find the parameter to have only torque assistance. In every case, It seems we need to reach...

Re: high turn count 9C motor.

You have RH and FH motor for Rear Hub and Front Hub. You have 154 and 205 version 154 is smaller in term of diameter and 205 is bigger. both have more or less the same torque. You have 7x9, 6x10, 5x12, ... 9X7 would be 9 strands and 7 turns. Chose depends of wheel diameter and torque, speed needed. ...

Ok, U1 plus Q3 and Q1 have a *VERY* high gain while they are active, so it's not surprising that they oscillate. C1 provides damping to the circuit. try boosting it in 10x steps. (Q3 holds the voltage of it's gate relatively stable when it's on, so C1 may need to get really large) R3 + RV1 + R2 als...

Hi, everybody from Germany for my first post at Endless! I am also interested about BMS developed by Silicium. It should do the entire job to manage A123 battery pack (cut-off at low and high voltage, balancing at the end of charging) with a standard charger. I have planned to perform one with A123 ...
