NEW to this but need help

[RayofSunshine]

I have 3 x Mira 25 batteries. I bought 2 additional batteries from trade sparky fitted one without an issue dut the supplied lead was to short for the fifth battery as the manual says not to stack modules in more than 4
Can anyone please advise what lead I need and where to buy it from
Also I am hoping to increase the number of batteries further to a total of 7. Is there anything I need to consider or be aware of
Thanking you. In advance
Cheers
Ray

You need the extra length cable pack see here -

It's the same lead set for HV2600 and Mira batteries
