Which is as useful as a chocolate teapot, I would like to set my temp cutoff at 2c and stop discharging before I got to 0c and also have the charge relay still active so the battery can charge back up.
The exact opposite, I want to stop discharging at around 2c (hopefully I will not get there as I have a temp sensor start to warm the Winston cells at 6c via heat pads) but I would still want the charging to still be active if mains/solar was available.
@CliveS Unless you have a special use case, I think you may have got some wires crossed here. For LiFePO4, minimum charging temperature (usually 0*C) is higher than the minimum temperature for discharging.
In what scenario would you require or want to cut charging at a lower temperature than discharging?
Could anyone share with us the super secret price for a 16cell 48v setup?
Too funny, I knew my question would be answered with a question, I gave enough information to get an answer!!. No one wants to just blurt out that it’s VERY expensive, kinda like buying a fancy car, if you have to ask how much, you probably can’t afford it..
@Kingdaddy it feels like you think this is some sorta 'gotcha question' that proves a point. When in reality you asked a question, then got upset when someone asked clarifying questions to fill in the details not included in the original comment. If like you said, you are positive you gave enough information to answer the question, why haven't you just gone and answered your own question?
To draw a silly analogy, your conduct is like walking into a pizza place and going up to random customers asking how much a pizza costs, and when they start to ask "what size, and how many toppings, any extras" cutting them off and saying "see I knew it! nobody wants to tell me the real price, expensive! I gave you all the information you need to answer my question" and somehow feeling like you proved a point.
I for one definitely consider the 123BMS quite expensive, I also find the pricing of it, and other high end BMS' a little less intuitive compared to commodity BMS'. But I don't think its some sort of conspiracy to hide the price from me. Its just a modular, semi-customizable system, not a one size fits all solution.
That said, it would be nice to have some reference points for the rough cost of a complete 4S, 8S, 16S basic system. Same holds true for other semi-modular BMS' like Chargery and Electrodacus.
There are many simple, cheap-ish BMS' if you want simplicity of pricing and product.
