Agreed... that is what I am seing also.... about 100 watts of heating per day

Bah! I think it is more than enough. If your battery is in an isolated environment (insulated box)... that is more than enough to keep it over freezing using very little power. My opinion and real life experience

Do you absolutely need a relay or you can wire the heater pad (that has the right amperage and voltage ratting) DIRECTLY to the JK without a relay? I think I am reading that I do not need one

For me a picture is worth a 1000 words.... was one ever produced (to connect a heating pad)

Do you have a link to your 2P 26650 nickel strips?

Where did you get the battery holders from ? I have been looking at some bulk deals on Aliexpress but they seem expensive still... About 200$ CAD (140 USD) for 2000 holders that support 1000 cells. I have been looking at spring battery holders instead... The cost will be much more (650 $ for...

I am currently processing the same type of cells. They are version A however and most likely more used than your. I will also be capacity and resistance testing everyone of the them. I am shooting for a 128P8S setup. What is your strategy for spot welding them together? How about the fuses...

600$ USD per 100 Ah roughly for new cels vs 160$ here + the cost of nickel strips and copper wire... let's say 200$ A third of the price + it's better for the environment

Oh for sure... just the cables will cost me a lot... I konow I will need more I am doing this to 'replace' a gas generator fed panel I use when we lose electricity here in Canada. When I lose electricity, I switch a special breaker to flip from grid to an external source (generator in this...

I would like for some of you to chime in here.... I'm thinking of buying 12 of these banks: https://i.ebayimg.com/thumbs/images/g/4WoAAOSw~ZJbg~~B/s-l225.jpg These banks have 96 of the following USED cels: https://www.batteryspace.com/a123-l...r26650m1b---un38-3-passed-and-iec-listed.aspx...

Limitation in my opinion... you should be able to configure the MP50 like the shunt. (Just saying) Thanks all for your input. I'm goint to make a USB charger with my extra cell since I am 3s now..... photos to come.

Yes ... that is what I want the maximum to be. I have three lithium Ion cells that are rated to a max of 4.2 volta each and I do not want to exceed 4.1 volts each... hence the reason I set 12.3 volts for the battery pack. That is what I set on the MP 50 bit the battery icon show it almost...

Anybody know why my MP50 is not displaying the right battery level . correctly?

I am assuming that you are talking about the large rope in this photo... These are for the movement of my chicken coops. They are called chicken tractors and they are based on the plans of Farm marketing solutions... Every day, I move the chicken tractor forward by pulling on this rope. This...
