Good day . I really liked your video). I have the same torqueedo battery. I changed the 18650 batteries. I collected everything and does not show the volume or voltage on the panel on the top line and the motor does not spin. tell me what is the reason?

Hi Rus, Yeah, saw it the other day. So You sized up to 10 in parallel from 8 batteries, Right ?
Did You try 8S 20P ???
I checked it out the other day on the FB page of Alexey. Have no acc on FB but I can see. Nice project, 2, 8 kW, very impressive and the weight is very acceptable.I see You use 72 batteries. So that would be 8S 9P. Is that what Torqueedo is using standard in the newer 915 battery pack ?
Alexey, what batteries are You using and how do You charge ?


Yes, I also think it´s not worth while experimenting with the controller. I believe at the time it was designed specific for the Panasonic CGR18650CG - 2250 mA.
Charge constant 4, 2 V / 1500 mA / max 20ºC / 2 hours
Standard Discharge Rate 430 mA
As the capacity to charge the internal battery is limited by the controller today I believe the best solution is sizing up the number of batteries in parallel corresponding to the internal battery according to use of boat/speed and then using LifePo4 batteries for range on the charging port @ charge rate max of the Torqueedo charger 90W. This way You can use solar for the LifePo4 charging as big as You want. This way the motor controller is functioning correctly and should also make the batteries last a lot longer as there are less deep discharge cycles


BMS of controller is very sensitive with max 34 V. What I don´t know is ??? Can the BMS handle more then 90W ?

By the way... have You guys checked out the newer 1103 Ultra Light ?
3HP, no more gears and noise and plenty of power. Uses the same 915 battery pack.
Of course the price through the roof....AS EXPECTED. What a freak show. Most likely that is a standard China Town motor. No wonder almost nobody wants to go electric.

I apologize for reviving an old thread. I just found this, and am very interested. This winter I am hoping to do something similar for my Travel 1003. Were there any complications with the BMS? How confused was the motor when it comes to reporting SoC (state of charge) or remaining range? Anything else that the computers complained about because of the larger-than-expected battery?

Just did the the math on the 2, 8kW pack. Acc to the numbers from Torqueedo 1003

Minimum Speed 51, 9 hours Range 194, 4 Km
Medium Speed 18 hours 100 Km
Full Speed 2 hours 45 min. 25, 2 Km

Well, I doubt You can run this motor for 2hr 45min with out over heating and the controller shutting down
