Re: Super Soco TS Upgrade

What's next? Do I need to thtough it all away, measure each individuel cell again? Should I only measure voltage or also resistance (how?). The area affected I think is what received the damage. Let's say a cell on the other side would only "realease" energy at its highest rate and that's its jobb....

Re: Super Soco TS Upgrade

...You take 95V and 150A from your battery (which is 14.25kW) and you step that down to a lower voltage with higher current, which is what the motor sees. Is the effect / The real world performance that it is 33kw because the phase amps are 350 but the voltage just lower of course or are you saying...

Re: Super Soco TS Upgrade

Ahh, 95V that's a lot, I was thinking on 60V. Do you have pictures of that all, sounds like you have a lot of stuff packed onto the frame. And how did you connect the Super Soco connectors to the new controller? I have removed a lot of plastics on the inside which will give you more space. Also the...

Re: Super Soco TS Upgrade

Its calculated in a different way Battery amps and phase amps. Phase amps is true battery amps I guess but modulated or multiplied by a performance controller. I don't know how it works just that it gives a lot of power. Battery amps max is 150A Battery phase amps from the controller into the motor ...

It can do 30,000w 0-70 in 5s and 0-100 maybe 10s. Cars are gone in a second 100 meters behind. The Malectrics welder is better than the sunkko. Good choice! qs 273 motor is the one I think that the soco has. Meaning that you already have the motor. To know for sure is to open up and se for yourself(...

Re: Batteries involving 40T, 30Q and MJ1 cells. Preferences and opinions.

The reasons are: weight and smallness. I want to keep it as small and light as possible. I plan to take it with me when I park the bike. 200 Wh is about all I need, and even with just that I expect to stay in the 80 to 20% SoC range. I would add that if you want your bike to be lighter then you cou...

If you have any use of them or spare time to sell them after you have tested them straight to be working - that adds value.

As a percentage, I drop 6.43% of the voltage on a 8000w output with my battery. Are you happy with your battery and the power it gives to you or do you want a better one? The Chevy volt battery is probably the best in terms of longevity. Maybe because of the internal "cooling system" that cools the...
