Interesting project ... everything sounds very well pondered, but asking 4.5Kw output from a Neu 1515 sounds to optimistic. Efficiency at high Amp levels might be less then 80% requiring your battery to feed up to 5.4KW (900Watt wasted in heat) meaning 270A@20V (assuming around 3.3V per cell). Don't know if the windings of the 1.5D will hold up to 270A even for short bursts.
Which ESC do you plan to use? Jazz 55-10-32, Neu 1515/2Y (1100kv), 9s2p A123 (27v), up to 3.1KW Latest video with eagletree Data inserts: Run on asphalt |
