    14s20p PowerWall

    Ho ok, each side seemed a little extreme lol What about the other side, what should I use to link the cell to the bus bar ?

    What fuses to use ?

    I just begin : Is it needed to use fuses at each end (+ and -) of each cells ??

    14s20p PowerWall

    Hi guys, the building begins ! I used rePackr to make my 14 sets of 20 batteries : Then, I made the barbus : Ready to sold : Soldering the fuses : I have a question about the fuses :Is it needed to sold one fuse at each end of each cell ??

    What fuses to use ?

    Great, according to your experience, what AMPS should I choose ? (cells from laptops batteries)

    What fuses to use ?

    I bought this few months ago, is it good for this purpose ?

    What fuses to use ?

    Hi Guys, I'm preparing my 14s20p battery for my workshop, in order to power 5m LED strip and maybe one inverter to power my tools sometimes. About the bus bars, I cannot find the fuses on AliExpress to link each cell to the bus bars. Where can I buy those ? Thanks.

    What voltage is too low ?

    What about AWG 34 or 35 copper wires to make fuses 4A ?

    What voltage is too low ?

    I will use 12V buck converter for my lights, and the inverter will be mainly use to run some low power drill (dremel), or heat gun, so clearly I will need a pure sinewave inverter. Thanks for the help ! by the way, my harvesting is going great :)

    What voltage is too low ?

    Actually this was my question :) I wanted to know for which appliances should I go to pure sin wave inverter.

    What voltage is too low ?

    By the way, why would I choose "pure sin" or normal inverter ?

    What voltage is too low ?

    for budget battery

    What voltage is too low ?

    OK, I understand now. Speaking of BMS, what is the minimum model you recommend for 14S ? Is something like this enough (granted there is no heat sensor) ?

    What voltage is too low ?

    What I meant by "series", is "series pack", which are in parallel (in my example 50 series pack in parallel), anyway, we speak about the same thing. You are funny, but no matter the cost, if you double the number of cells will, the price will increase by 100%, but your point is valid about the...

    What voltage is too low ?

    I'm asking this, because I will mainly use my powerbank to light up my parking box with 12V LEDs, but I want to be able to use some electric appliance 230V at around 1200W, but it will be quick, like 10seconds, or 20 seconds. Even if my battery pack doesn't last long. So I'm trying to figure...

    What voltage is too low ?

    By the way, I'm testing some Samsung ICR18650-26C, and the datasheet says : Discharging: 2.75V Cutoff 520mA Standard 5200mA Maximum Does "Standard" means "continuous" ? and I want to autorize my appliance to get 4A for a short period of time, how long can I do it ?
