Depends on your understanding of a flat battery.. if there is no activity then the battery is below the acceptable charge voltage for the BMS (battery management system) circuit board to recognise the flat battery. By putting another battery of equal voltage in parallel that in fact has charge (voltage) then the BMS will recognise and deliver a charge to the circuit.. After a few seconds disconnect the second battery source from the flat battery and the BMS should continue to charge the flat battery as usual..!!

no it was awful. we hgad a teacher in university that had a doctorat degree, however he was not a teacher and after 3 weeks of his teaching we all sign a letter to the university saying he was drowning the fish with his knowledge that he could not communicate and he was fired on the spot and replaced. this guy is exactly the same: worthless

Wowww.... this tip saved my life!!... This is exactly what I had to do to get charging again, not a full BMS shutdown. I am hooked to your site forever, and why does Enerdrive not tell you this I wonder? Thank you, thank you.

Why didn’t you make a demonstration?

Another great video. From my understanding using the “supply” mode (momentarily) in a Victron Smart Orion DCDC charger would suffice? Thanks

Thanks for the info, I watched another vid similar by another youtuber that showed ways you could kick start it with many 12v methods just to trick the charger into realizing a battery exists there to be charged. I was lucky My electrician i called didn't come and come through the manuals and found out my AC to DC charger had a mode i could run 12v without a battery and that kick started it just turning that on for a few seconds then switching back to charge lithium.

Thanks, your simple explanation helped me revive my lipo4 battery!

Great Video Bud,

Will this work on a solax battery please. I have two 6.3kw linked. I think I may have one that has shutdown as they only charge to 40% then start sending excess power back to the grid. A step to step guide for a solax battery would be very helpful. Thanks so much

I have a 110ah slimline with inbuilt DC DC charger. It has ran flat. What is the best way to recharge?

hello can you explain to me the function of the wire on the lin socket? is there a 12 volt present if I connect it to negative, should it interrupt the 200A' relay?

Great hack. My 6 vah battery went dead and got zero voltage at battery and charger. Used a car charger at 10 amps [2 amps didn't work] and charger started.

How to revive an SOK Bluetooth Lithium Battery and bypass BMS The BlueTooth has discharged the battery and you can't charge it. Open the battery and charge the cells directly for about 10 minutes - after try charging from the top through the BMS. If it doesn't work, recharge all the cells bypassing the BMS to nearly 100% capacity. If the BMS still won't work: Disconnect all power from BMS, let it sit overnight, make sure you charged the cells without the BMS to about 80% - reconnect the BMS, start charging normally through the BMS on top of battery.

Would a 12V battery start up a 48v ? I have only one 12v

Hi, I have a 48 Volt 10 AMP battery that will charge for around 5 minutes then when I use the electric bike it will die very very quickly within 15 seconds how do I revive that battery. It does have a built in headlight and that's the only way that I can think of to discharge it. Or should I get another 48 Volt good battery and just go positive to positive negative to negative any help would be appreciated thank you Andrew

Probably it's loo late to reply..don't know whether you will see this. But anyway, you should try this procedure called battery balancing on your battery pack. The device used in this case is called a 'battery balancer' and costs about 9,000 INR here in India. Or you may catch hold of someone in your area that repairs lithium battery packs and ask him to do it for you for a fee. Hope it helps. Regards

this also works on lead acid and glass batteries, I have scored many a free battery because of "hibernation mode'

Thanks, just about to buy a lithium battery.

I have a dead 36v what do I do then ?

Please I need help. I have some pieces of lithium phosphate batteries 🔋 that don’t retained charge 🪫 and I noticed the electrolyte seal covers are broken 😞. Can that cause a problem to the batteries? Can I add an Electrolyte to the batteries cells? What type of electrolytes can I add. Please kindly help me with a tips or solutions: Thanks

did not show how to do it show us

Carefull, not every battery has a safety bms, so li-po battery's and li-ion cells inherently do not have bms on the cells themselves, you need to add it for them to be "safe"

My battery is working but the display is not going on

Next time try to find a room that is acoustic friendly

But how do you flatten the batteries if they have bms low voltage cut out ? Surely that would make it impossible to flatten beyond the cut out level

@sonicspring6448

Because the battery looks as if its output voltage is zero at the terminals, but the pack of lithium cells inside still probably have some charge left. The terminal voltage is zero because of the internal contactor / relay / disconnect device which most Li batteries have now for safety reasons.

Here's what i WANTED to post that morning: Body Heat to Warm the Battery, keep it under a blanket with you and your Heat will warm it. Don't touch it directly but keep the blanket a few inches within the battery and it'll warm after awhile. Can keep it under the Blanket with you to Warm it up then run it and keep Alternating Keep it under glass in the Sun If you have a Car keep it on the Dash until it's Warmed, keep checking on it though cause even in Winter the Dash can reach 100° Wrapping it in Clothes or Blanket to insulate You posted this 15 Hours ago, so I'm assuming it was getting closer to dark, and you were frantically searching for an answer. I'm in NY area.

Any experts out there?? So is he essentially saying is to connect a DC power source in parallel to the dead lithium battery n jump start charging it that way?? Any gurus PhD’s out there to confirm this??

Wretched! Shoot it again as though not trying to direct loading a truck with mulch from a distance, but gesturing to the point and on topic, illustrating as ye go. Speech was very very off pace and enunciation. Also ofc. people should be using pulse chargers, see "Unravelling the Mechanism of Pulse" for an article that should get you to an open access Science article.

What the hell is he talking about?

wth, its youtube, show your work

lol...zero for communication...repeat 6 grade please

Does a serious over charge degrade the battery and if so how to fix like an undercharged if applicable??
