Guest Posted June 8, 2016 Share Posted June 8, 2016 What do you think of these RELi3ON 100ah batteries specs @plonkster? RB100 Final.pdf Quote Link to comment Share on other sites More sharing options...
___ Posted June 8, 2016 Share Posted June 8, 2016 Impressive. Now what do they cost? More or less than 7k... that's the target price in my mind :-) Sent from my GT-I9195 using Tapatalk Quote Link to comment Share on other sites More sharing options...
___ Posted June 8, 2016 Share Posted June 8, 2016 Looks like around 1300 USD, or almost 20k each. That is to say, good specs, but ultimately it's still 3 times too much. SilverNodashi 1 Quote Link to comment Share on other sites More sharing options...

Guest Posted June 8, 2016 Share Posted June 8, 2016 About +-R 16,806.27 excl VAT worst case ... per batt. How does that compute to Eskom rates? Quote Link to comment Share on other sites More sharing options...
___ Posted June 8, 2016 Share Posted June 8, 2016 12 * 100 * 0.8 * 2000 = 1920kwh. Make it a round 2000. Then it costs R10 per kWh. That's diesel generator territory. Sent from my GT-I9195 using Tapatalk Weasel 1 Quote Link to comment Share on other sites More sharing options...
Guest Posted June 8, 2016 Share Posted June 8, 2016 Plonkster ... why 2000? That is 100% DOD? Apples for apples should it not be 50% DOD calc? Quote Link to comment Share on other sites More sharing options...

Apples for apples should it not be 50% DOD calc? 2000 is for 80%. I used that one because it's listed on the spec sheet. Saved me from having to read the chart. But okay, lets do the math for 50%. 12*100*0.5*6000 = 3600kwh If the battery goes for R18 000 (for argument's sake) it's still R5/kwh. I know people pay that for UPS batteries (where other factors might be more important, like fast recharge and high discharge rates), but it simply won't do when lead acids to half that (have to be replaced more often, yes, but a farmer cares about rands per hectare, and so do we :-) ).

Guest Posted June 8, 2016 Share Posted June 8, 2016 Agreed ... seems to be lead acid batteries like i.e Trojans' are simply not that easy to beat. Quote Link to comment Share on other sites More sharing options...
___ Posted June 8, 2016 Share Posted June 8, 2016 Just now, The Terrible Triplett said: not that easy to beat And almost completely recyclable. The only downside really is the weight, the space it takes, and the messiness... boer maak 'n plan though. Quote Link to comment Share on other sites More sharing options...
Guest Posted June 8, 2016 Share Posted June 8, 2016 I ordered a wood box specced for 4 x batteries, with wheels ... going to put it in my braai room and insulate the box a bit. Fan mounted on the op of one side, to start when there is excess power on the load dumping function of the Morningstar, to extract the hydrogen. If it works, for I can measure the batt temps, then mine is sorted for a very long time, winter and summer, for the braai room gets about 45 in summer, 15 in winter.
