-The most beginner tolerant and value-for-money battery bank is two **6v deep cycle flooded((you can/must add water periodically))"​golf cart" batteries** [[electrical:​12v:​parallel_serial|wired in series]] to make 12v.  This will provide 200+ Ah (amp-hours) of rated capacity.((100+ Ah of usable capacity)) ​ This bank gives Bill one normal day's use and and about a half/day of of reserve (ie, a day with no charging). ​ A set of golf carts like this will be sufficient for most needs and does well with 200-500W of solar panel. ​  Deep cycle batteries are typically [[electrical:​depth_of_discharge|discharged no lower than 50%]] as this is a good usability/​lifespan compromise. 50% DoD is about 12.2v for lead-acid chemistries. ​ A [[electrical:​12v:​lvd|Low Voltage Disconnect]] can help prevent deeper, damaging discharge.+The most beginner tolerant and value-for-money battery bank is two **6v deep cycle flooded((you can/must add water periodically))"​golf cart" batteries** [[electrical:​12v:​parallel_serial|wired in series]] to make 12v.  This will provide 200+ Ah (amp-hours) of rated capacity.((100+ Ah of usable capacity)) ​ This bank gives one normal day's use and and about a half/day of of reserve (ie, a day with no charging). ​ A set of golf carts like this will be sufficient for most needs and does well with 200-500W of solar panel. ​  Deep cycle batteries are typically [[electrical:​depth_of_discharge|discharged no lower than 50%]] as this is a good usability/​lifespan compromise. 50% DoD is about 12.2v for lead-acid chemistries. ​ A [[electrical:​12v:​lvd|Low Voltage Disconnect]] can help prevent deeper, damaging discharge.
