So far after testing several tools I want to share that Schematics.com seems to be the one with the most features, free and easy to share. Here are some screenshots of my diagrams: Features that I find important are: You can move components and wire will follow You can add your own...

15 amps run for over 20 hours.

Sure, this might take 60 days, as I paid ocean freight only. I already have test equipment and I also paid for 1 cell to be tested and I added one extra cell for discard. Yes, they are going to laser weld a threaded post to them. Totally agree with you. I can't be paying half the price and...

Free Schematics.com, you can draw and have some features that most will find important: You can move components and wire will follow You can add your own components It will create you a bill of materials You can export the files to print You can share design with others to collaborate It...

I ordered them, sales person said Grade A and capacity of 300 or more. PDF's call 1500 cycles and 0.5C discharge rate.

Found the solution: https://www.bluesea.com/products/7702100/ML-RBS_Heavy_Duty_Remote_Battery_Switch_24V I can use a combination of the Inverter Relay + MPPT Relay + one of the ML-RBS for the DC bus and I will be all set.

This is really usefull. @Dzl definitely wiki worth stuff. Is there another guide for resellers ? Threads on resellers 100 pages long maybe we could find a way to organize reviews and valid tests together.

I think there are certain features of a diagram software that are important. PIN/Wire Naming and setting the location Having a Bill of Materials Ease of Sharing so others can see and edit without having to buy a license Ability to move components around without having to re-wire So far I've...

I'm building an overland truck that I wanted to minimize energy loss and heat buildup. The truck has a 24V alternator so I'm designing a 24V LiFepo4 system as I'm able to have most of the components at 24V and few under the inverter: The space for the batteries is limited and I could go with...

Batteries arrived, packaging was GREAT. Absolutely flawless packaging. I would give a 10 out of 10 so far. All items have been received. 50 days from the order date. ? first impression is great. I can't start testing them tonight because the cells are very cold, looks like they were on very...

I want to start with a big thanks to @svetz , @Hedges , @Solar Guppy , @ncsolarelectric , really appreciate you guys helping me here. It took me a while to reply as I was digesting all the good info you guys shared. I'm going to share the info I find here so it can be used for others in the...

Ok, so the batteries arrived and I got one random sample to test. It arrived at 3.3V and I charged it at about 10Amps for several hours until it lowered the current to about 300mah. See picture bellow: Then I wired it to my discharge tester And after 24 hours I have not opened...

Looks like Draw.io is the simplest to start. Victron components are available and it's a easy way to create a visual diagram. Example: https://drive.google.com/file/d/1_cgSoFykH7BRqq-ECAIdWs_vHTshDzvJ/view Library: https://drive.google.com/open?id=1L_dxgf-cquCFIR0tncsziaa8h54rxXhX

So far deligreen gave two prices: $102 for grade B and $182 for grade A. I’m going to try to get spec sheets. I don’t need over 1C discharge , my peak should be around 0.5C I also checked if Xuba (Selina) can get it threaded, their price is better and they guaranteed capacity however said it...

I'm trying to get pricing on them but haven't found online sales. Do you know if they support an API/REST to get the system status even without their cloud ? Do you pay extra for 25 year warranty ? On their docs they state 10 year default and 25 year option.

It seems that a "line side tap" would be the solution to resolve this. I don't see disadvantages on this when not using a battery system.

I did test my batteries, took over 20 hours at 15Amps. no trouble.

That is a good idea, however Victron calculator does not recommend using the 250V/85 as all panels series voltage will get very close to it. I would have to get a charge controller from down under I think Outlaw solar has a 300V MPPT. I'm trying to avoid having two charge controllers to reduce...

Did you consider an Electrodacus BMS ? The BMS has good features and can help you with protection. From my research to protect from over discharge you can use both Inverter for AC loads and a battery protect for DC loads. For over discharge you can use the MPPT solar to stop the charge. Now if...

I recommend schematics.com , free, easy to share, and can export drawings and bill of materials.

That was Xuba. Deli green is $102

I'm curious on this. Deciding on going with mosfets or contactors for 24V@200A max load 50A nominal. The entire Daly BMS alone is cheaper than the contactors.

Just logged in, works fine.

Awesome work guys.

After some research I found that using all the panels in Parallel will be supported and that should lead to best performance. This also helped: https://footprinthero.com/solar-panel-series-and-parallel-calculator

I'm planning to get the MC4 20Amp fuses connected to the panels, then connect that to a 8AWG MC4 cable and combine it all to a 4AWG cable, might need to use a busbar or weld it all together.

I'm on the same boat itchy to purchase at least 16 280ah cells and might increase up to 32 cells if I can get full confidence in the seller however so far I'm very confused with all the long posts that sometimes just make me super confused.

For 144 cells I would place order 1 by plane and test before doing the full order.

I just reached to Xuba and they are out of EVE cells and offered CATL 300ah but I have not seen any specs on that. Do you guys know of another trustworthy reseller for EVE 280ah cells ?

Yes, it's cheaper to get 5 SmartSolar MPPT 100/20 than 1 250/70 however would that be the most efficient way (consider that they all have a small loss to operate) ? Lots of wiring and space needed also. I really need to save the space.
