    Dat gaat er nooit komen, dan loopt onze roverheid teveel geld mis. Als het bekend gaat worden op grote schaal dat je als particulier veel meer geld overhoud als je het in accu's stop worden ze per direct voor de particulier verboden. Er zitten plannen in de pijpleiding om per wijk een groot...

    Nee je mag niet zomaar stroom terug leveren, kan zelfs dood door schuld worden. Stel nu er springt ergens een stop uit of een storing of what ever. Een elektromonteur gaat naar het verdeel station toe van jouw straat en meet 0v op de kabels als het bewolkt is, hij gaat aan de slag en de zon...

    Als je energie opwekt ben je een ondernemer voor de wet. Je kan ook niets voor niets je btw terug vragen. Gebruik je 10kwh per dag moet je al 30kwh per dag leveren om mogelijk gelijk te spelen. Overdag wek je op je krijgt 9 centen per geleverde kwh, maar savonds kom je thuis en je koopt een kwh...

    Jammer dat we zo ver uit elkaar wonen. En tja het is niet echt verwonderlijk dat de dealers niet behulpzaam zijn, immer hun eigen monteurs moeten ook wat te doen hebben.

    Last fire.. :-(

    Sorry, no my friend. it is just the other way around... They keep pumping A's into that poor cell...swallow or choke...a fuse prevents both.. They want to balance...hence a self discharger...more dendrite forming, hence higher ir henche heating up... Now this circle you will prevent with propper...

    Last fire.. :-(

    My opinion about a "runaway": There are other chemestries that get some unbalance and will cause a thermal runaway(famous red sanyo's 18650) Short circuit due to other causes: a pack that is NOT properly balanced. a not matching string, 15s 420Ah cells and one 105Ah cell. short...

    Last fire.. :-(

    Dendrite is occurring/building up with every cycle. The IR is also building up. You will notice this in time. If your string is original a 100Ah, most of us with take it out before it is getting dangerous, meaning: I don't think someone wants to prolong the "suffering" of the string when it is...

    Last fire.. :-(

    I read some very interesting arguments against what ever problem a cell can have... Yes we can put pressure sensors heating sensors bms ect to protect a string and what ever system that we can think of... But arent we forgetting the most important thing? Cell level fuse? The fuse will blow when...

    What happend to the prices of lifepo4

    I found out there are a lot of reasons why they are almost 50% cheaper for EU inhabitants. Vat is increased with 21%(import duty is now calculated, white board criminals) they will get a bit back in there shipping costs. Chinese economy is shrinking for the 3 quarter(3 x 3 months) this time...

    I dont think they are new, but second handed, i am almost sure.... New ones are as 2 as much more expensive. they came mostly from ev's and roberments energies storage projects. For our goal they will last a 20-30 years, easy. New ones will last a minimum of 8000 cycles for our DOD(20 to...

    Indeed if you calculate the calendar life of li ion or lifepo4 with the cycle life in terms of how many times you will do a full cycle a day. Throw in your kwh price from the grid compared to a gasoline operated car or your household daily consumption relative to heating/cooking to get rid of...

If a cell is unused lets take a 100ah cell no matter what chemestry. It has a left over of 100ah: rated new unused. If a used cell test for example 97ah from the...
