I am about to order about 100pcs of CATL “310ah”. Has anyone got their order and tested them ?
I don’t want t purchase that many batteries without knowing the cells are new.
I am in talks with third party quality control company to check these cells before I commit. Plus some of us already...
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 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
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...
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...
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...
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...
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
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...
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...
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...
