I have sent you firmware versions 1.5 2.5 and 4.5 to assist in updating the firmware to the batteries.
You will require a Rs232 to usb modified cable to do the firmware update.
We can supply one to you but request you only cover the courier costing to get the cable to you.
Our address for pickup is:
Unit 2 Point Business Park
29 Marinus rd
Milnerton
7530
Please inform the courier company driver to ask for me by name and to ask for a RS232 Cable
