Thank you

Can you explain why a busbar is better? I'm using a busbar for hooking up all my other circuits but why would using a busbar for attaching my batteries be better than attaching them together? Thanks

Perfect, I put a 125 on battery A and a 125 on battery B. If I pull (for the sake of discussion) 200 from the bank. I know the 200 will be split between the two batteries (so 100 each). The total of the two will be 200 but each will provide 100 amps each. So my question is this: what...

Hi, I want to use 3 batteries in parallel. I was going to string them together + to + to + and - to - to -. then attach one + to a busbar and one - to a busbar. I read somewhere that I could attach all the + and all - directly to busbars instead of attaching all batteries together. Do...

Good Morning, I have 2x206ah SOK batteries mounted in Parallel. Specs say maximum continuous discharge 100 amp per battery. So 200 amp when paralleled. I have the opportunity to buy a AIMS 2500W inverter charger. Let's say I was to draw 2500W from that device... The amp draw would be...

Yes and no... I am not talking about calculation or anything like that. I just want to know what you thing what method is best between the two I draw above.

What would you consider big

Ok so it is a good practice to use the chassis? I did some investigations a found that the the battery neg is connected to the chassis. The wire is probably a awg 2 (much bigger than the 4 I am using). That is the only connection on the negative side. It means everything is using the chassis...

I know the battery neg is attached to the chassis with a cable. I will check the size.

Hi, I'm about the purchase my batteries... I'm wondering about Ampere Time. They have self-heating options of different capacity. I leave in Canada and we have pretty harsh winters. So the self-heating option seems good. Does anyone use their self-heating batteries and how did you find...

Hi Out of curiosity, are the two diagrams below equivalent electrically speaking. I mean for the chassis ground. I want to use the chassis for the negative return instead of running neg wires back to each source. Thanks

I will freeze yes; I don't mind that too much. What I want though is that they warm up before allowing to charge. If that's what they do, I'm happy. My question was more about are they reliable, is the BMS reliable and will the electronic do what it's supposed to do.

Good Morning, Happy new year!!! I'm attaching 2 batteries in parallel (SOK 206ah). I would like to put a fuse on each battery terminal. I want the bank to be fused at 250Amp. I understand I could put a 250amp fuse at the positive terminal where the wire is exiting towards my kill...

Thank you! 125 at the first battery terminal and 250 at the second battery terminal (equivalent to you combined).

Ok based on the answers above, I can do 125 for each battery, or 125 for each, and 250 for the combined. here's a drawing with two options for wiring the Fuse Terminals. In drawing A, the second fuse is combined as current from both batteries is flowing through the fuse. In drawing B I...

Both fuse blocks are on their respective batteries (SOK 206ah)... I should have mentioned it... Sorry. Then the cable exits toward a Kill Switch and Busbar. All wires are 2/0. I changed the image

Yes, thank you. Equal length wire for sure... my drawing skills are not that great :-) but thx for your comment

Ok I get your point and that is exactly what I did for all my circuit. A red and a black creating a closed loop from my "house" battery. 100% with you on that. Less interference, cleaner design, easier to troubleshoot in case of problems, etc. What I don't get though, is whether or not I...

It does make sense. There are many wires leaving the positive post of the battery and only one for the negative and, that negative is connected directly to the car chassis. This mean everything running in the ultimately runs back via the metal frame of the car. That's my understanding...

Not sure I follow you, I looked around and there are many ground point throughout the vehicle. Yes several connections are made at each point but there are many of them. This leads me to believe the frame is used abundantly
