Ok, let's go for an average draw then. Let's just assume they use up 3000-4000mAh in those 5 min. That would equal an average draw of 36-48A (if my math doesn't fail me here). So, actually around the same as with a resistor bank. So a 40A
discharge (not talking about 40A
charging here!) should still be perfectly safe, just as I don't consider running Mod class to be dangerous. Seems a bit randomly chosen...
