OK I am trying to finalize what I need for this spring project so I can buy on a budget, putting a material list together, etc. I hope you folks don mind another question or to or three....Stop Keith
I have been doing a lot of reading today and YouTube including a lot of Will's stuff. For the sake of this discussion lets assume 4 battle born in parallel (100 to 110Ah each) or 4 6V GC2 in series/parallel (220 to 255AH each) both delivering 12V to a 3000 inverter or inverter/charger such as the Victron 3000 unit.
Please check my math.
BB have a max discharge rate of 100A. Not sure of the limits of a GC2 6V. Using this rate and using the bluesea chart I need 4AWG between the battery's (possibly 2awg) and 2/0 to the inverter. Inverter will be whiten 6 feet of the battery pack. However I am curious if I need to up-size between each parallel connection for the amperage output accumulating between connections in either set up. I am wanting to fabricate my own cables, but want to do it once for either situation, so the sizing needs to cover both situations.
The best battery cables, for an RV should be made out of welding power cable. However the front bay where the battery's will be is not 100% environmental proof and per Will I should consider marine grade cabling which is much stiffer. Thoughts? I am leaning towards the welding cable for ease of routing
Last is the cable crimp lugs. I know they should be pure copper or tinned copper. However there are numerous hole sizes available. BB 's come with 5/16 bolts for their lugs and it appears the Trojan is the same. Is this standard across the brands for the GC2 batterys?
Last What are the good sources for these materials (cable/lugs) as I am finding prices all over the map. Looking for good sources. I have seen several positive posts about batterycablesusa.com
Last - battery box. I found one to fit the 4 CG2's https://allbatterysalesandservice.co...atteries-gcq-g but not one for the 4 BB battery's. Yes I know I don't need a box for the BB's, but I want to use the space over the battery's if possible for soft stuff.
Thanks for any help
