Growatt GBLI 6531 6.5kWh battery pcb's

Just in case anyone is interested I have had some pcb's made to connect to the battery harness in the Growatt GBLI 6531 6.5kWh battery.
I've done 2 types. One is a breakout board so you can just connect your own bms wires or balancer. The Second is similar but with JS connectors.

I've also done another to utilise the LED's on the front of the battery.

That's interesting. I remember a few years ago there were dozens of super-cheap Growatt batteries on eBay that were bricked due to failed PCB. Not seen any for a while though.
12x 340W JA Solar panels (4.08kWp)
3x 380W JA Solar panels (1.14kWp)
6x 2.4kWh Pylontech batteries (14.4kWh)
LuxPower inverter/charger

These are for the later 6.5kw battery that also seems a bit susceptible to U/S bms's
