Are you connecting directly to the battery or comms hub when you are trying to update the batteries?

Directly, no comms hub.

 

[Markus_EG4]

Directly, no comms hub.

I have never seen HW 2020. and its a lifepower4 battery

This one?

10Gtek# USB to RS485 Converter with CH340 chip Compatible Win7, 8, 10, Vista, Linux, MAC OS https://a.co/d/3ElYYIo

Yep that's the one

Do I need to apply this firmware update to the 24 volt life Power Batteries which I have in series to get to 48 volts and then in parallel with two of the 48 volt life Power Batteries?

 

[Markus_EG4]

No this is only for the 48v

 

[underdog5004]

No this is only for the 48v

OK, thanks

I want to point out that after the update, the comm cable with conductors on 7,8 no longer worked, and I had to use the Jerry rigged 1,2 cable to monitor these batteries.

Thanks for the input I’ll follow up

After the update 7,8 uses 19,200 baud. 1,2 still uses the default 9,600

ALCON,

After updating LP4 to 3.26.

The 7,8 pin communication cable will only read if you change the default "App BaudRate" to 19,200
Pin 7,8 is read only

Pin 1,2 (read/write) still uses the default 9,600 BaudRate

Thanks I'll give that a shot tomorrow

Will there be similar firmware updates for the 24V and 12V batteries in the future or do they not suffer from the same issues as the 48V ones?

Do you have issues with you batteries charging to 100%?

The only issue I had when updating this weekend was, I had to restart the program once for two of the 6 packs. Otherwise, all went well.

I did it the way @Markus_SignatureSolar explained. Fabricated a cable as shown in the video by @Zapper77.

The packs all reflect the same "Full Bat Cap" of 99.8 whereas before they said either 98.8, 98.9 or 100.

Unfortunately, still have the same 4 cells not functioning like the other 92.

I know this update is for the Lifepower 48v, are there going to be any improvements also for the LLs?

 

[jmjack]

There is a new firmware available on the EG4 website https://eg4electronics.com/downloads/

This is for the 48V Lifepower4 battery. This firmware will help keep the batteries Top Balanced when charging.

Hi @Markus_SignatureSolar - Will the improvements only been seen when the inverter battery setting is set to EG4 or will those of us using USE settings also experience it.

The LLs are solid they dont have any issues reported.

this was meant for close loop but works open loop as well

I have issues where, in a pair of 24v batteries in series, one will be at 27.0v, and the other will be at 28v. The drift gets so bad that one batteries shows cellOV alarm. About once a week I have to disconnect these pairs and reconnect in parallel, let them balance each other, then reconnect in series.

I was hoping this firmware would let one battery turn its Charge MOS off while the other was still on, to allow both batteries to reach the same voltage (1/2 nominal bank voltage each)

Is the 24v version recommend for series connection?
