I love the weight of it too. And yes it can be paralleled with a regular lead acid battery. I called xs power the other day and they told me it can be parallel but I forgot to ask them if it can be used under the hood. If it can’t be used under the hood then I’ll just leave my d3400 and use this for the back. It will save me from having so much weight in the back.. two xp3000s and a d3100 are heavy as shit lol.
