Yes, I've had to struggle with the S-class battery issue. When I did submerged patrols, I would generally run at 1.5 kt., or thereabouts. That was the only way I could recharge the battery in one night.

Thankfully, those days are over. A major goal of ISP was to fix the horrendous battery issues.

Try using this mod loadout (with SH4 v1.5):

RFB_2.0 (Real Fleet Boat)
RFB_2.0_Patch_23April2010
RSRDC_RFB_V575 (Run Silent Run Deep Campaign)
RSRDC_RFBV5xx_Patch1
Improved Ship Physics 1.1

[You can forget RSRDC if you want, but most people like it.]

This will get you much better battery performance. It won't be quite up to the specs I listed, but pretty close. Follow the directions in the mod, as regards recharging. Other classes of US subs are fixed, as well.
