A Kontronik Jazz 55-10-32 is able to provide peak Amps above 100A. I have several logs on 10s1p A123 with a Neu 1515 and Neu 1512 "proofing" this. I see regular Peaks of 2KW and the max of my batteries seems to be around 2.5Kw. No cogging so far and no thermaling (small heatsink added).
2 new HV ESCs will be released by kontronik in spring. Jive 60+ HV and Jive 80+ HV. Both able to be fed by up to 12s lipo. 60a and 80A cont. With proper cooling (heatsink) they will be able to provide twice those numbers. Burst currents are not published yet. Both will have a car program with forward only and proportional brake. Both will have an integrated BEC wich can be used up to 12s lipo. And they will be waterproof. Preliminary prices: 250 Euros for the smaller one and 300 Euros for the Jive 80+ HV. Both could be interesting choices for HV applications.
