Admin,
On the description page it says:
"Note: Please be aware that if the batteries' Battery Management System (BMS) is activated and the battery voltage shows 0V, you must use a compatible Li charger to reactivate our Li batteries."
Does this only come into play if there is a complete discharge of the battery? Does it just require a charge controller that supports Li batteries or does it need a Renogy controller to reactivate them?

Thanks, I was asking if it was specific to where it has to be a Renogy CC

You must use a compatible LFP charger that is compatible with the Renogy LFP specs. In our note we allude to our Rover Li which supports a activation feature for LFP batteries. -Renogy Team |

AND, it's good to know that possibly from now on Tatt will not make statements as to how a charge controller can wake up a totally discharged lithium battery...Just sayin...Smooch, Tatt. I GREATLY respect the tech of current lithium batteries and cheer their progress, but for me they are far too early in their development to invest such big bucks in them...Lithium tech is really the center of battery development science today where almost every day someone discoverers a totally new way to make them mobetter and even cheaper and safer...Presently that is including graphene tech, but perhaps tomorrow yet another discovery...It is a fast moving target where were I to jump in today, I would regret my investment tomorrow. Nah, I'm too old for that fast moving tech...Plus I have lotsa faith in the scientists working hard behind the scenes right as I speak to produce a breakthru that will last awhile and justify my additional investment. I know little about Renogy, and if they invest in developing the science of new tech, or if they simply sell it to us...Either way I have no complaints because I am just a consumer....but yaknow, I do pay attention. |

Without the wake-up feature to reactivate and recharge batteries, these batteries would become unserviceable and the packs would be discarded. The Rover will apply a small charge current to activate the protection circuit and if a correct cell voltage can be reached, it starts a normal charge. -Renogy Team
Here it is just in case you miss it...
Smooch....

Thank you, I was just going by what I had been told by Renogy.....
I personally don't know crap about Li batteries other than they are very expensive....

Has anyone actually tried this??? How do you apply a small charge current across an OPEN CIRCUIT? I have 3 100 ah Renogy batteries that shut off at the 10v mark, apparently. Open circuit. I have a $600 Morningstar 60 amp controller now but I see the Rover only goes up to 40 amps and will go POOOF if I attach it in place of my controller. I see Optimate makes a lithium battery charger/"saver" that supposedly resets the BMS. Anyone try those?

^^^ Why would you let you batteries get down to 10v in the first place?? ^^^^^^ That's the bigger question.....
