Amazing. Unbelievable helpful. Thank you!

My 8 3.2V 206aH Lishen cells finally arrived!! Now to hook them up to my 12V system. I have a Victron Lynx Distributor where all components are fused. The battery bank was going to connect to the left-most positive and negative connection points. However, after reading a bunch, I've decided to...

I'm working out the same model. Can you please tell me how exactly you connected them in parallel? Did you stack the pos and neg lugs on top of each other, connect them with bus bars or wire, or some other way? For some reason, this has me tripped up...

Question on this: I have 8 cells wanting to make what you're talking about. But how would I actually parallel them? Are you paralleling the BMSs too? Or are you just creating the 4S packs, both with individual BMSs and then connecting Pack #1 pos terminal to Pack #2 pos terminal (and same with...

It certainly does. I am also using a Lynx for my fuses. However, I only have one. I was thinking of putting an inline ANL fuse on each positive side. Then adding the lugs on top of one another on the left side the Lynx distributor where the wires come in. Do you think that would work fine too?

This question may have been answered (potentially many) times before but I'm struggling as a noob. I have two separate 4S battery packs (8 cells in total) in a 12V system. Each one will be equipped with its own Overkill 120A 4S BMS(es?). I have a typical off-grid, camper van DC load and a 2000W...

This is exactly what I'm wanting to do. Can I ask how you set it up to the Lynx? Did you stack the positive lugs from pack #1 and pack #2 and the negative lugs from pack #1 and pack #2 on top of each other on their respective pos. and neg. battery input site (left side of the Lynx)? Or did you...

"poor boy" version of Victron is what I'm shooting for ;)

Thanks @HRTKD. I checked in with a Victron sales rep who said the Cerbo only works with Victron components. So, unfortunately, the components I have will not be compatible with the Cerbo. I think I can either do what @Diysolar123 said and slightly lower the float and absorb voltage profiles on...

Thank you. I thought about this multiple charging problem. My solution was to only have one charger going at one time. And to shut off the other two when not in use. But if it's possible to have either the mppt and AIMS charger going at the same time or mppt and DC-DC charger going at the same...

Thanks for clicking in and having a look. Electrical diagram is attached but you can also go here: to view it. My main question is in regards to the battery-to-battery charger which is not connected to the Victron Lynx Distributor currently. Because it will have an inline fuse (and the...

Perfect; thanks so much Steve.

This will be my first international order. How would you suggest contacting Amy (AliBaba or direct email)? Also, does anyone have her contact? Thanks :)

Good to know. I'll get the real ones and make sure they're compliant on the listings you suggested earlier

Ah, thank you. I take it they're basically the same as the caps used in rewiring light fixtures in your house. I was thinking of using the Wago connectors for basically the same thing, but maybe a quicker, stronger connection...

Good idea. I'll try to do just that. Thanks again.

Thank you for taking a look. I like the idea of the remote sub panel. I might stick with the two fuse centers then. I think it gives me more options in the future too to potentially add on other DC items. My other question is some folks were saying it's redundant to have an ANL fuse and a...

In my design I have many different DC loads, all individually fused, which are not series connected together. For example, Bedroom reading light/USB #1 had a separate fuse from Bedroom reading light/USB #2. I have (24) individual DC loads and the AC-DC distribution box only holds (15). All the...

@Dzl and @smoothJoey thank you for letting me know! I uploaded the gif here:

Hey all! I learned a lot since my first proposed Electrical Diagram. If anyone could take a look at my second version, which is quite different, I'd be beyond grateful. This is a 12V system with 3.6-4.8kw battery bank (300-400aH), 2000 watt inverter, DC-DC alternator charging, and 620 watts of...

Would I need to purchase more than just the item above? In my understanding, the box contains the cells in a case outfitted with a BMS that has temp control.

That's a great deal. Did you inquire off of AliBaba? If so, did you send a form of the template email Amy suggested in "How to buy Chinese batteries"?

Looking to purchase this 12v 400aH battery pack from XUBA on AliBaba. Seems like a great alternative to purchasing my own cells and creating my own battery bank. (I need between 320-400aH @ 12V.) I'm apprehensive though... It a bad idea to order these battery packs rather than the individual...

So I think I’m too late to order this 12v 400aH battery pack from XUBA. Are you saying if requested today the quality might be impacted? Here is the AliBaba product I was looking at: Also, is it a bad idea to order these battery packs rather than the cells because you can’t really individually...

This is really helpful. I'm having a very tough time figuring out the actual amp draw of my battery bank (I have a standard camper van setup with a solar charge controller, inverter, etc). I have two 205aH 12V batteries wired in parallel for a 4920watt system. I also have a 2500watt inverter...

@seanski that is funny! I was planning on going with Big Battery but they raised all their prices recently so kudos if you got in before that! Also, I'm still a bit unsure on their terminals. For the amount of amps going through the 12V if you hook up more than one in parallel it seems like you...

@seanski I decided against my original plan to use 24V and an all-in-one unit to instead go with a 12V system. My reasoning for doing so is because I do not have that many 120v AC loads, but more importantly, I'm using this in my camper van and planning on having the alternator help charge the...

Hey there! I actually have not updated it yet but I’m about to! They came out with a 12v larger MPP all-in-one that I’m adjusting my entire schematic so that it runs off a 12v system bc I heard the losses from the DC to DC step down can actually be quite a lot (20%- even if it says it’s 96%...

I'm not sure why BigBattery suggests the 6AWG Anderson plug to rings cable. Would I be better off making my own super short 1AWG Anderson plug to fuse (on the B+ side), then continue 1AWG to the bus bars, and continue to the Growatt? Also, would I have to run that 1AWG to the DC to DC fuse...

Thanks so much! I will adjust for your first three points. To the last one: The main battery has a built in BMS with over and undercurrent protection up to 300A. The all-in-one inverter Growatt system has internal circuit breakers. Would the battery and Growatt still need fuses??

Hello! Newbie poster here. (Please be kind but all assistance is greatly appreciated.) Can someone please look over my wiring schematic for this 24V system for my camper van? It uses BigBattery's battery power bank and connects it to an all-in-one Growatt unit. There's a DC-DC step down...
