Enough for what? Over here most tracks and racing series nowadays have a limit of 12A - not all that much higher. IMO 10A is enough for most people.

If you're racing with folks who do the whole 40A+ thing and believe you're a good enough driver (being marshaled just once will cost you way more than you will ever gain by high amp charging) that it truly matters and are willing to replace your batteries accordingly, then no.
