Re: Beverage storage area is the coldest it has ever been - 35F
Totally true, personally I don't consider myself a prepper by any stretch of the imagination, I am however almost self sufficient from a food standpoint, but it's extremely difficult to co…1 · -
Re: How does battery voltage translate to watts stored? Does it?
Battery voltage does not directly indicate watt-hours stored. "Standing" voltage measured at least 4 hours after charging or discharging can give you an idea of the battery charge level. BU…1 · -
Re: How does battery voltage translate to watts stored? Does it?
Read this part of your post again. You said 15 watts. (That is per hour, expressed as 15 watt-hours if you run one hour) In the next sentence, you jumped to 15 volts per hour instead of watts. You ha…1 · -
Re: How does battery voltage translate to watts stored? Does it?
Adding to what Marc says... For a first estimate, Lead Acid Batteries are fairly close to 100% "amp*hour" efficient... If you have a 100 AH battery and pull 50 Amp*hours out of it (assuming…1 · -
Re: Off Grid Telecommunications Plant Battery Project
Telcom batteries are designed for only a couple dozen or so discharge cycles, as backup generators come on line. They are designed for long Float life and are often swapped out at about 50% of warran…1 · -
Re: AGM battery Lowest voltage
For most AGM designs, I am a strong proponent of staying in Absorb until end amps are reached, with a limiting timer overlayed. Concorde Sun Xtender specifies Less Than 0.5% of the C/24 capacity at t…1 · -
Re: IBM's new battery, we hope!
Dave, I will have to check out those Grapefruit! The two Costco's nearest me are over an hour away, so we go less often but really bulk up. There is good eating in freshwater too! Saltwater fish…1 · -
Re: IBM's new battery, we hope!
It is interesting though not surprising that the "greenies" care not about the horrific consequences of Congo cobalt mining. Going out on a limb and thinking perhaps lithium based energy c…1 · -
Re: Pros and Cons of different battery types?
Lead acid, despite their shortcomings when compared to more modern technologies, definitely has its advantages when cold is a factor, they are able to tolerate extreme low temperatures if fully charg…2 · -
Re: Two MPPTs, two pv arrays, two battery banks, but one combined output?
Usually, there would be only one 24V battery bank... In your case, both series strings of four 6V batteries would be connected in parallel to make a larger 24V bank. Then, both A and B controllers wo…1 ·
