I'm in the process of adding a 2nd battery system to my 100. Going to run a fridge, some extra outlets, led lights, etc. and want to have a house battery. I'm planning on using a Blue Sea ACR, but am torn between the 7610 and the 7622. From what I can tell, the only real differences are the higher amp rating and the ability to self jump with the 7622. Does anyone know if there are any other advantages of the 7622 over the 7610? Do I need the higher amp rating of the 7622 on my 100. I think the stock alternator should be enough for my needs. Being able to self jump start isn't worth the extra $100 to me, so unless there are other advantages, I'm leaning toward the 7610. Thanks for any information or advise.
