315-585-9826 is our phone number. We can make your cables any way you wish, left flags, right flags, straights, or whatever. The ends are not universal, but sized for POS & NEG. The 1/0 cable we use is heavier than 1 gauge. Many electrical problems are traced back to the battery cables, by either being too small a gauge to begin with, or aged & corroded ends. Think of battery cable as water pipe, as the pipe ages, the ability of the pipe to carry water diminishes. It’s the same with battery cable & the ends.
