Not a single response ? Where is Steve ? 🤣. Just emailed batteryhookup about this too. You’re suggestions are greatly appreciated

quick over view of my system. 2 packs each contains 2p16s 280a LFP. Total of 62 cells. Each set has brand new JBD JBD-AP21S002 7-21S 300A BMS. Individually they work like a charm. I have two bus bars way too oversized for this but when I parallel these BMS one doesn’t get charged only one...

Ah Steve! ?. You’re right 200 is actually what I mean to say. JBD has the 300. Split port ? ? nope I have ordered the JK from batteryhookup it should arrive in 4 days. It seems these JBD are hard to beat. Come with cables already connected (huge deal for me, with relays means can actually work...

I saw that site earlier. They don’t have the 300a version and never seen that site before today. Good to know they have BMS that can be delivered that quick. Thank you

Thank you this was my plan B. I was hoping to take advantage of the high balance current. Anyways I thank you for your response

Hello team. I need JK Smart BMS 48v 300a and I am in the Midwest. I need this like today. ?. Does anyone know anywhere in the lower 48 that sells this ? Thank you

I will have to check this when i get there will post back what I find. But why would batteries do this now ? Maybe loose connectors overtime ? setup is stationary

My MPPSolar inver 11kw has been running for 14 months paired with 5kwp everything was smooth until yesterday inverter stated to act weird. It shows it was shut down because of the voltage going down to 48v (which is the way I have it setup. Checked evething waited until the morning as soon as...

I had this issue and now it is resolved. First of all if your BMS seems to not boot anymore. don't worry connect it to the PCS (still you will not see the battery stats) its normal. 1- try different firmware. i had to try like 4 different firmware from Daly before it was successfully...

and these did not work for my BMS failed to recognize. you can actually try multiple files until it works aprently this is not harmful

Well, I Issue is resolved after Daly team sent me multiple .zip files. multiple firmware update failures. with " Enter Firmware Code here" errors. I want to report there is a hope. After the firmware updated successfully the BMS came back to as normal.. No more Negative (-) while the BMS is...

I know about Daly BMS showing - (Negative numbers) when charging the batteries and showing. Positive when discharging this never created an issue but here is what I have discovered today. My BMS would show the negative (-) when charging and it would trigger the high voltage cell voltage 3.65...

Yea, any update on this please ?

this link does not work. i would like to know more about the 9kwh packs you mentioned

cool stuff. I i have about 5 mppsolar inverters from 5k to 11kw something like this would be really nice and helpful. specially if this gets contributed by the community. currently there are like 3-4 similar programs and non of them is complete i think the reason is not being open source...

Any luck solving this issue i have exactly the same issue here. also have the same setup of 32 cells too?

I have 205pcs from Amy didn’t do capacity yesterday but they seem brand spanking new. With me paying PayPal as backup Amy is the best. Will update later with actual numbers

This had me laughing hard.

That is very unique way of doing things. although its almost impossible to understand how the 16s is connected

very good idea. coming right up.

i have responded to your PM.. its funny old days we used to say PM now they are calling it DM ?. glad to see someone that says it the right way.

Massive off grid project. I will try to post. I am shopping for solar panels close to pulling the trigger for Shingled Solar Panels from BlueSun. ?

To be honest this was my first order with Amy. Even tho she was not the cheapest she was offering guaranteed and PayPal payment which was not something everyone was doing. Plus these are about $130pcs from EVE directly. I am assuming she is taking in lots of them and making profit that way. I...

Nope just Grade A cells

Just ordered 205 Pcs from Amy. Over $121 a cell. That is huge difference. But hey Amy is proved to sell good cells. This is interesting at least.

My next step. Thank you

That looks like power station. Nice tho almost zero resistance and V drop in those connections I bet

Yea 3” is way too wide now it’s starting to sink in. I am going to find a way to cut it in half. 1.5”

Very true. I just couldn’t stop my self.. haha I did the calculation this can do around 1000a ?. I also was inspired by this picture.

After long research of high amperage bus bar I decided to go to my local metal shop and pick 12ft 1/4 x3 copper bus bar and yes I asked cut it for about 2ft bars. this thing weights almost 40lbs. I have batteries coming by the end of the month. what did I learn here ? Yes this is expensive...

Mind sharing this “other company that accepts PayPal please ? Some earlier mentioned XUBA does not accept PayPal anymore. Thank you

This is not good news

Hello everyone. I am about to pull the trigger for large order (about $10k) for 302/310ah CATL/EVE cells. here is what I need to know before I do this. 1- I was not able to find even 1 seller that wanted to do PayPal payment. Most of them said TT or Ali Credit. My question is does anyone know...

What seller please ?
