    What do you reckon your total costs are there, Scott?

    I spotted this...

    Mastervolt MLS Lithium Battery – Glasgow Angling Centre

    Hmmm... £675.99 for 30 AH, anyone?

    You should think about going into business for yourself.

    The 39 Samsung batteries I used came to about £100. You can get them for about £2.70 each when you buy them in bulk.
    The Vruzend kit to connect them all together was about £40 but if you have a spot welder or don't mind a fair bit of soldering, you could get the nickel strips for less than a tenner.
    The charging leads are just a couple of quid so you could do it for about £110 or so, all in.

    Those GAC batteries are a bit steep, even for an off-the-shelf job.
    We just got a pair of Pylontech lithium batteries for the house to store surplus power from the solar panels on the roof.
    Each battery is 2.4kwh or 50ah at 48 volts and cost £700 each.
    That's about the equivalent of 200ah at 12 volts !

    I use 110Ah Exide deep cycle solar system batt now for 7 years, when not in use I store it properly and charge often, here is the problem.
    Put whatever you have heard or been taught about “Deep Cycle” and “High Cycle” batteries out of your mind. Every lead-acid battery can be deeply discharged. What is important is the number of times each particular battery can be discharged at a chosen depth of discharge (DOD). For example an Excis 100 battery (102Ah) from First National Battery can give 950 cycles (load shedding occurrences) if only 30% of its capacity is removed each cycle, 500 cycles if 50% is removed and only 60 cycles if 80% is removed (based on a 25°C operating temperature and correct charging).
    Do not size your system so that you remove 80% of the batteries capacity each cycle and expect 2 years battery life as you will more than likely only get 2-3 months life!
