Based on yall's recommendation, I bought a Powerex MH-C9000 a couple of years ago. Now, I've gotten an alternative power system up and running and I'd like to be able to use the C9000 to charge AA batteries for my flashlights, powering the C9000 from the giant battery bank for my alternative power system. The C9000 has a nominal input voltage of 12VDC, but it doesn't specify the tolerance on that. The main bank will drop to the low-to-mid 11s during the worst discharges and then rise to the mid-to-high 14s during charging. Will the C9000 tolerate this?
Yes, I've already contacted MAHA, but I've not gotten a response.
