Inquiry (采购产品): Battery Cable I need 2 lengths of battery cable @ 15 ft. each and 4 connectors to connect the auxiliary batteries on my RV to and existing battery . Do I need larger than 4 gage because of the distance? Also would you quote two 6V Trojan batteries, approx. 250 amp hour each. Thanks.
