[QUOTE="hispls, post: 8659044, member: 614752"] How far away are you from 1st? Alternator is internally regulated (I have no idea why Nathan did that). I've seen 14.8 charging briefly here and there but normally it likes to charge 14.4. If I externally regulate I'm going to 18 anyway.... why stop at 15? My big amp makes crap loads of power at 18V and my 6 channel is regulated power supply so if I pull a terminal at 5S it'll still deliver full power. I'm so far from actually needing these to be "stronger" though. Voltage barely moves with just 1 amp and the subs won't last even 30 seconds on 2. I'll need to find a free week next year to tear down all my 15s build up 8 12s rebuild the baffle to fit those, then get the second amp in there. You'll want 4" wide if you plan to have cells side by side. These round cells are appx 2.5" diameter so 3" wide would be ugly. Too narrow for 2 cells and too wide to mount cells next to each other without rows shorting. I think 1.5" for a single row might be cutting it close really, you'll wind up wanting some wiggle room when you line them up most likely. China sells some connecting hardware. There's some copper straps that'll buss cell to cell and there's some pieces of inside threaded rod if you want to go end to end but you'll still need something for end caps on either side. Both were kind of expensive but if you don't have time to cut and drill bar may be worth the extra money. [/QUOTE]
