>I think in theory you could just apply 4.2V * number-of-cells & stop charging when the resting voltage of the pack reached the charging voltage

In practice it kind of works (i.e: if you have three cells in series you can charge them with a 12v wall wart), but it's not a very good idea because there's nothing to balance them.

There are numerous cell-balancing circuits, some batteries come with them, some do not and instead they have the bigger connector and the small connector for cell balancing.

That rudder is complete garbage. The boat would only reliably turn right.
