Cheapskating wont work !!!
After 35 years of doing solar power, I can guarantee that you will end up with a dead battery bank. The three Powerline batteries will shortly fail. You will buy three new Varta's to replace them, ONLY to find the Varta fitted now no longer matches the three new ones.
Second set of batteries will also be a failure!!.
TRy putting 3 off 6 inch wide tyres on your car, and a single 5 inch tyre. Its only a "small" discrepancy.
60 Ah and 65 Ah is also only a small discrepancy. Internal resistance of the new battery will be MUCH different to the old ones.
