I'm glad to announce that I ordered the 6kW Tangent Kit
I was just being buy the battery but I have a small doubt.
I had planned to use the 6kW as a 3kW by limiting the max current, and so preserve my small battery which, up to this morning, was 4s+4s+6s built with Multistar 16000mAh lipo packs.
(16Ah 10C) 4s: 80$ - 1390g
(16Ah 10C) 6s: 112$ - 2044g
--> So 14s1p 16Ah 10C for 272$ / 4.824kg
Now, I looked for increase the discharge rate (too hard to not use the full power of the 6kW )
(8Ah 10C) 4s: 45$ / 0.705kg
(8Ah 10C) 6s: 50$ / 1.025kg
--> So 14s2p 16Ah 20C for 280$ / 4.87kg
Does it means that 14s1P is finally a bad choice !!!???
I also search for a meanwell able to charge the 14s (with three BattGo BG-8S for monitoring), but still not found. If someone have a solution for a bulk charge...

Remember, the engine is just a conversion device, it can only convert the power fed by the battery, so don't skimp. Voltage sag is the power killer destroyer of batteries.

This is at worst a minor annoyance for literally seconds, use 14s or you'll be wishing you had the first time you try it. Just charge the 14s pack fully and use the motor to drain the top 1% off the charge if needed, reset the ESC warning, resume your ride as normal.
