 The original wire of soco TC  from battery connector to controller is very thin, and very long. with original set up I got about 2400W But inside the battery pack it use XT60 and 10 AWG wire, which seems more reasonable for a 40A load. wire near the air breaker. the contact does not seem good enough for me. Battery connector side. some one says the connect is heated in long drive. This is the connector from motor, there are hall sensors and  Also a motor temp NTC sensor(the white wire) which did not connected. I change the connector and the wire from battery XT60 to ESC, in basic, since the battery pack inside use 10 awg and xt60, it should be good. but for future changes I use a XT90 and bigger wire. with same battery package, I got a slightly better result. 2665W   From previous search in 02, I knew the ESC can take higher voltage, but it would go into protection at 75V. Original battery pack voltage. Adding one cell in serial So, I added a lipo cell at external, ...

 What is the exact power of Soco TC?? On the DM of western countries, it mark as 1500W I know from some other's testing, it can do more, but how is the efficiency? Here is the answer. https://supersocoforum.com/forum/main/performance-measurements-tc/#page-content It seems ?

The soco TC does required some info from battery pack, if you want to make your own power pack with own BMS, then it is necessary to have this module. Other wise the bike with show a 94 alarm. This kind of product is selling about 100yan in china. I have done some test in some previous posts, the communication system of my soco TC is a RS485 with 9600bps. base on some captured message, when system on but not riding the bike,  I'm not sure where is the query command comes from, but the one to battery is: C5 5C 5A AA 01 97 96 0D Here is a result with arduino 328p https://github.com/Ldsrc2008/SocoTC-BMS-cheater I disconnect the battery BMS RS485 port, and connect the RS485 cheater. No error code is presented(normally you get a alarm94 if TC does not find it's BMS.) here is a alarm code list from soco. But, my display has no battery indication. original one arduino cheater My guess is that the display unit sent it's own request for data. Redo my research on net: this forum ment...
