Boost converter busted
A quick test of a motor revealed their current usage at 12V is 3A. The L6234 only goes up to 4A if they're lucky, so a boost converter would also require custom H bridges. The polulu boost converter itself would only output 3A at 20V for a short time. A custom boost converter & custom H bridges would be needed, many lbs of copper.
There might be marginal losses from battery resistance, wire resistance & connectors, bringing the practical current at 12V to 2A. The leading theory these days is now to get some 1S 5Ah batteries & wire them in series with the 12V batteries. It's the cheapest way to test a marginal increase in torque. It might also extend the range enough to not have to carry around another 5Ah.
There's a 5060 motor which might also give marginal improvement, but above 50mm, hobby motors go to $300 & weigh 5lbs. Skateboard motors become cheaper beyond 5060, but also weigh 5lbs. For a new vehicle, the 5060 would definitely be the way to go.
Anyways, with the levitator overheating, the starship model is manely a refrigerator magnet.
