    Running parallel battery pack. I need help please.

    but will the controller demand 40 from each battery or will the controller recognize that one can drain faster and do so?

    Running parallel battery pack. I need help please.

    Both batteries are 35AH 72V the only difference is one is capable of 100A and the other is capable of 80A If the parallel connection is trying to draw 80A would that demand 40A from each pack or would the controller try to draw more from the 100A pack. This is the answer I need.

    the 100 amp pack is Panasonic NCR18650GA 10A 3.5AH and the 80 amp pack is samsung 35E 8A 3.5AH think this would be all good

    Running parallel battery pack. I need help please.

    I have 2 battery packs (#1) 20S 10P 35AH 80A discharge (#2) 20S 10P 35AH 100A discharge There is a separate BMS on each pack Can I run these 2 batteries parallel on an 80A controller 5kw hub motor

    is there a way to discharge cells just for the sake of discharge need to bring my batteries all down to level and I still have over a hundred left. Im currently pushing out about 12 cells a day. Can I accomplish this task any faster without buying 3 more chargers (pondering doing so)? is it ok...

    do you think i can just limit the draw from my controller as i've already bought everything . I am still in the process of testing the cells. The other pack I had, I used less than 15 times and never ran them to hard. They were 13s 8p and had a 20a bms on them.which i thought was a bit low. I...

    I am asking, I have 200 35e cells so a 20s 10p would run at 80a as each cell is rated 8a each continuous but the max output on the datasheet says max 13a so do i get an 80 a bms for my cont. rating or my max......................?

    when you say max do you mean 130 absolute max output, or 80 for my 80 continuous 80a?

    New build help. Is this safe?

    while i appreciate the info i just need someone to answer if my pack design is going to work. Can i make a pack in any shape I can think of as long as it follows the basic rules of flowing energy. Do the twists and turns of my pack effect my power or current in any way.

    Given that I add the last cell and all the cells are good, will the pack be safe to build in this fashion?

    New build help. Is this safe?

    I am going to put a 10th cell there I just want to know if the procedure is correct. I know it may seem silly but i had a thought that current path changing direction lots of times would create heat. Also I do plan to verify each cell. I bought the pack new and it has maybe 20 cycles on it. I am...

    New build help. Is this safe?

    This is the battery idea. Is this going to work( 20s 10p) I know number 18 only has 9 cells. This is my first battery build (sick of "wasting " money) and I'm trying to make sure everything is overlooked by individuals with more experience.

    would this also be the case if i always paid very close attention to charging. I thought 60 would be good as the max is 13a i know if i ran them like that they would die pretty fast but i figured if i overshot the thresh hold by accident I wouldn't have to worry about burning the bms. I ordered...

    I bought a 5kw kit off of aliexpress(one of the QS models). It came with the 80 amp controller. Claims can be used with a variety of voltages from 48 to 72. Currently i am powering it with a 20s 3p battery comprised of 21700 40t cells with an 80 amp bms. So i have some questions :evil: 1. Is...
