why such a need for a big battery. bigger than can fit under hood. I use my extra battery under the hood lots for work lights and radio etc and have lots of power left over.
No real reason other than reassurance. Winching draws a ton of juice, so I want to be sure it can take the long draws and slow recovery. To my knowledge, there are no atv/motorcycle batteries that are deep cycle so I will have to go with an automotive style.
Sure, a 2nd smaller battery would work but in my humble opinion its not the right tool for the job where a deep cycle is.
