Can you imagine how much power it requires to use a winch? Getting those big monster trucks from those muddy swamps out doesn’t seem like a job that you can do with low power supply.
To make the winch rolling, you’ve got to feed it with a lot of power. Without the best battery for the winch, you’re doomed.
And having just a battery that provides a lot of power isn’t enough. It needs to be sustainable too. If it drains fast, then it’s no good.
