<div>We do have batteries that can be charged at 3C but I have only designed one mobile medical unit with that capability. It required 2 50A shore power connections or could use the onboard 20kW generator. Makes lots of heat doing so and heat is battery enemy #1, molten salt batteries excluded. Lower operating temperatures is a good reason for using lower C rates.
