What happens here

The hosts take a moment to discuss the general principles of cordless tool batteries. They explain that voltage (like 24V Max) relates to the power the tool delivers, while amp-hours (e.g., 2.0 Ah, 4.0 Ah) relate to the run-time or how long the battery will last. They use an analogy of a car's engine size (power) and fuel tank size (run-time) to illustrate this concept. They note that the kit appears to offer a good balance of power and decent run-time, though continuous heavy use might require frequent recharging.

Goal: Explain the significance of battery voltage and amp-hours for cordless tools.

charger I'm gonna jump in here because I want to just kind of break something down for you when it comes to batteries they're all basically the same well they're not built the same but they're the same when it comes to volts and amp hours and what that means and what the bolts is that's the power that the battery delivers the amp hours is the runtime when we're looking at a car like this the volts in this case would be the size of the motor or the power and the amp hours is the size of the fuel tank so on these tools they're delivering massive amounts of power but they're not necessarily delivering massive amounts of runtime so that means you're gonna have all the power you need but you may be going back to the charger to keep the tool running for longer anyway let's go see what Frankie and Sam let's go back to Frankie and Sam two of them they got the tool and power and they got a 4 amp hour came with a nice case though it's got wheels on it all right well I guess and try some of this stuff out as far as the two batteries will oh wait there these were a team these might have battery energy yeah these need to charge that one does what was that one this badly there's a battery yep this is a 24 yeah oh that's gonna be the driver there it is yeah it
