[QUOTE="Water Bear, post: 8822557, member: 673826"] Talked to Limitless and they said 15.5V at cold start is OK as long as you warm up to around 14.8 within a few minutes (he said it's OK if it touches 15 but should average 14.8, basically). Threw one of those free down4sound volt meters on the battery and watched it last night, sure enough it gets to 14.8ish after warmup but does oscillate between 14.6 and 15. Seems like LiFePO4 should probably work but it's kind of iffy to me. These are expensive batteries to smoke because you decide to risk it. Was thinking about going with a Cyber 12k for a while but there's talk that they really don't support anywhere near 12k. Better than a spare AGM, sure, but not near 12k. LTO is definitely the better choice from a technical standpoint - better C ratings, longer life, tolerates low charge, etc. The issue here is that I don't really want to do a battery delete so LiFePO4 has the "plug and play" advantage. I thought about going with a 16V LTO but my concern there is that I'll never be charging it properly and that might not be good for it. I know LTO is supposed to be fine going from 0 to 100% charge but still. And for 12V LTO my charging voltage is problematic. It's a shame you can't just use an isolator with AGM and LTO. [/QUOTE]
