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
Hello team.
I need JK Smart BMS 48v 300a and I am in the Midwest. I need this like today. ?.

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...
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.
