Standard lead-acid, maybe gel variants. Chargers designed for professionals, mounted on carts or trolleys. To inject more amps in the battery, you need higher voltage. So rise the voltage as much as needed, under a controller, to inject 50 amps (I don't know the actual figure). These things have instructions to disconnect the battery from the car before starting, to avoid damage to the car electronics. -- Cheers, Carlos E.R. ES🇪🇸, EU🇪🇺.
