Re: Victron smart 12.8v smart lithium battery
To be precise getting the cells balanced is getting then all at the same % SOC. If we have two cells with the same capacity, one at 50% and one at 51% SOC the voltage difference between them would be…2 · -
Re: Valence u27 12 xp lithium batterys
From what I can work out looking at the Valence website your batteries have the balancing circuitry inbuilt but unless you have their external BMS you will have no way of knowing if the battery is ba…1 · -
Re: Have Lithium Ion batteries come of age for off-grid systems?
This video https://www.youtube.com/watch?v=pxP0Cu00sZs, which is one of PNjunction's favorites gives quite allot of information on lithium ion battery coulomb efficiency and other interesting stuff.…1 · -
Have Lithium Ion batteries come of age for off-grid systems?
To me, this thread http://forum.solar-electric.com/discussion/351556/batteries-abruptly-stopped-holding-voltage-under-load shows up some of the major problems with lead acid batteries. * It is very d…2 · -
Re: Seeking Normally Closed Latching Contactor and Q&A about balancing my Li Ion battery bank
You are right, strapping the two cells together in parallel makes them into one cell as far as the outside world is concerned. It also means that the voltage of both cells in parallel are the same be…1 ·
