    12V LiFePO4 and NOCO Battery Discussion

    I have tested at below -10C and the voltage from the dc-dc did exceed 14.6V to about 14.8. But I guess that's a moot point if the Noco won't allow itself to be charged at those temps anyway. In the end I decided to use a Noco "Repair & Maintenance" charger on the old battery. It has a repair...

    12V LiFePO4 and NOCO Battery Discussion

    Happy New Year JoeS and iMievers!!! Well it's been a little warm in T.O., but finally last night we hit -11C and I tested at about -8C this morning surprised to find that our FLA battery still had enough juice to start her up after sitting in the cold for two days. (PS. I've sprayed the top...

    12V LiFePO4 and NOCO Battery Discussion

    :D :lol: Me stay focused? OK, so I tried this morning at about 3C and the FLA was sitting at 6.3V (deaders). Wouldn't go to ready, so I boosted with the Noco booster for a few seconds and she fired up. Took the booster off and she remained steady ready. Measured 14.6V at the battery...

    12v Battery - All You Ever Wanted To Know

    How about limiting the current to <10A ? How would I do that? Resistor?

    12V LiFePO4 and NOCO Battery Discussion

    Moderator edit: copy of previous post deleted to save space. I will check when the temp here in Toronto drops again. It's 13°C today, but will be colder next few days. I've got a little digi-voltmeter I want to use. It would be nice to put it in the driver's compartment. Are there any access...

    12V LiFePO4 and NOCO Battery Discussion

    I believe it's referred to as the "MCU warning light"? I was worried had damaged something with the booster. It's the Noco Boost HD, 2000A, GB70. I use it to boost my hybrid Silverado and my dad's old diesel tractor. When you connect it to the iMiev's terminals, it can slide nicely inside...

    12V LiFePO4 and NOCO Battery Discussion

    Thanks so much for addressing this JoeS! After researching a bit, your thoughts very much mirror mine, but it's great to have a second opinion. I did get some car battery size terminals with #8 screws the Noco required. They are brass or copper. I'm thinking about getting a Noco charger to...

    12V LiFePO4 and NOCO Battery Discussion

    I just bought a Noco NLP30 Lithium Ion battery which allegedly has a built-in BMS. Yet in their manual they specify using a Lithium Ion battery charger. The charge voltage is specified at 14.6V and max charging current of 24A. Any objections to dropping this puppy right in there and letting...
