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 · -
Re: Nickel-Iron woes.
Hi, That's even stranger. I can see the photos here, logged in or not, but not the ones on SPT unless I log in there. To save time, I copied the text from SPT, so that must have copied the photo…1 · -
Re: Newbie ready to go off grid
The best way is for them to invest in the first set of batteries, once they have "skin in the game" they will keep a much closer eye on things. And remember distilled water for batteries.1 · -
Re: Thoughts on the new coronavirus?
