Yeah, you're right Webster, been trying the same thing myself. In SH3 I had some success modding the type XXI recharge, but no luck with types VII or IX. In sh4 I had some minor success with the gato but not with Balao!!! Really frustrating. I was hoping for a change in SH5. After hours of tweaking type VIIa I gave up. I just assumed I dint have the brains to guess the formula they must have harcoded.
I had an idea this morning but couldn't explore it further as I had to report for duty at Mother's Day

. Can't write in detail as typing on an iPhone can be annoying at times. However I'm thinkig the motor officer batery recharge ability must be scriped somewhere, so I plan to have a look into the py files on Monday (screw work). Maybe that's the key. Or script a new ability (active one) that would decrease recharge times dramatically for a limited time (so you could rapidly charge from 5-10% to 30-50% in a few hours (3-4 maybe rather than the current 12). That would also solve krupp88's realism issue. Dunno just a thought. I honestly hope I could get someone interested into this, so we could solve this once for all - it really bugs me and I wanna nail it. I'll keep reporting my progress meanwhile!
