Going back about 35 years or so, guys racing RC buggies would waterproof their batteries and charge them in a bucket of cold water. I think they were something other than Lithium though. metal hydride?

I remember one guy got called for his race, he grabbed a pack from the bucket and disconnected it, looked at it for a second and threw it back in the bucket and shook his hand. "I'll use the spare"

NIHM and NiCD batteries used to be charged at high current on timer chargers. That practice has fallen away with lithium packs that you usually charge at 1-2C. Chargers of the same price range nowadays have better logic than a dial timer.
