Even more battery storage
I recently saw a batch of ten 70 AH sealed 12v batteries advertised on eBay. I just had to have them and made the seller an offer which he accepted. He shipped them to me on a pallet in only 2 working days. They are less than six months old and were part of a huge UPS back-up system for a large multi-national company which re-located.
I have wired them all in parallel, which gives me a capacity of 700 AH and added to my existing battery makes a total of over 1,000 AH. This should be enough storage for for several days of emergency lighting and computer use with my solar panels and wind generator providing the charging source.
See my home alternative technology exploits which are always changing and being improved, without spending a fortune.

Thanks for this, but I can't justify any more investment in wind power as the site is in a dip and the wind speed is insufficient to be viable.
Hi Nigel,
Excellent web site & blog... made me smile !
Just a little comment about the wiring of your batteries. When wiring batteries in parallel it is better to take your pos and neg connections from diagonally opposite terminals.... or even better, use a common bussbar and the same length cables to each battery.
Otherwise.... the battery at the "front" gets most use, resulting in uneven battery wear.
Very best wishes,
G.
