    12V LiFePO4 Battery Project - Suggestions Wanted

    With the smart bms, I can know if my car adjusts charging to the 12V battery according to the temperature. That is another reason I prefer a smart bms which is much more expensive.

    12V LiFePO4 Battery Project - Suggestions Wanted

    Thanks for your information. I am in the south western part of BC, Canada. It is not that cold in winter. It is just below zero for a few degrees for at most 1 month. And may be that is why I have not seen those battery warmer before. I will try it in case my battery does not function properly.

    Chalo, thank you for recommending Battery Hookup to me. That 74Ah is a little too big to fit into the space. I will the consider the 50Ah.

    Thanks for your information. My location will be below freezing for about a month every year. I have not come across such a battery heater. Could you send me a link of it so that I can consider if I am able to add it to my battery or not?

    12V LiFePO4 Battery Project - Suggestions Wanted

    Thanks for your comments. I like the smart bms because it can show me not only the voltage of the battery. I can see the voltages of all the cells, output current, charging current. With these, I can understand how my electric car will do to and need from the 12V battery. The smart bms will...

    Squeaking noise from front brake

    I think I understand what you mean. I had the problem in the rear wheel of my bike. SQUEAKING NOISE is the post I asked for help. And I solved the problem with Chalo's help. But in this case, it seems not the same. But I will try it when I have time later.

    The "Watch" feature

    It seems to me that the "watch" feature is not working for me. In the old version, I constantly received emails reminding me that there were new posts on the posts that I "watched". I forgot the term used for "watched" in the old version. But after changing to the new version, I seldom got...
