My cruises are generally 15-20 miles and my Trojans (6 months old) seem to hold up well even with stretches of 30+ mph cruising. Is it worth the extra $$$ to move up to 160?
Keep in mind the regular Roypow battery packs are only rated for 100 amps continuous discharge and 200 amps for a 10 second maximum discharge. This includes both the S51105 and S51160 Roypow packs.

I don't believe that the Roypow performance packs are available yet, but the S51105P and the S51160P Roypow packs are rated at 105 amps and 160 amps continuous discharge respectively. Both P packs have a 315 amp maximum discharge rate for 30 seconds.

Not only do you want to concern yourself with the amp-hour rating, but you also need to consider the discharge ratings of the battery offerings. I believe that your Navitas controller is rated for 440 amps ... I don't believe that you will want your battery pack to be the weak link in your system.

Do you know what your present amperage draws are for your various driving situations?

I suspect that your only choice (amperage wise) may be to wait until the S51160P pack becomes available.
