The problem: figure out maximum discharge amps. Potential solutions include: splice in a multimeter, run the drill until the battery dies and do math. My initial solution was to take apart the battery pack to see if the cells indicate anything. They were all soldered together inside of an internal plastic housing. I did not want to destroy this battery because it is still functional.

It would be wise to have the option to slowly titrate up the amperage to avoid an electrical fire. I'm sure I'm not the first person to do this.
Battery powered tools[permalink][rss]
Certain cordless power tools do not have an official option to replace the battery with a cable. The ability to do this effectively turns the tool into a corded tool. I might look into building custom power supplies for said tools. This could probably be accomplished with commodity hardware and a couple of cheap, sacrificial Chinese bootleg batteries. An inline circuit breaker would be extremely useful to prevent repeated trips to the breaker box. No other useful features immediately come to mind.
