Are you saying that is the way they work and others just don't know they take days to balance with a bms ? Do they take days to balance the pack ? If not then something is wrong with the setup ? With the pack or bms or the way it was connected ? How do you adjust the lvc for lipo ?

My Hyperion only stays in balance mode for a few mins and gets them within 8 thousands of a volt and that is for homemade A123 packs. ( it says 3 but the fluke says about 8 ) How long does this bms normally take to balance ? And how do you adjust the lvc for lipo ?

That is what I am thinking too. Lipo BMS for sure.

Does the pack balance ok with a rc balance charger ? That would be the correct tool to charge with. And leaving them on charge for 4 days ? Did you get ideas like this from reading es ? What is your LVC set to ?

pm returned neighbor :)

Yes. Thank you for this info and taking the time to take pictures and post. You may have saved some members from buying junk like this.

I have never seen them this low before. http://www.buya123batteries.com/category_s/1515.htm With the good service I have had with A123m1 cells from 2006 I am thinking these could last as long as Windows 7 ? (2020) :) Maybe longer ? They last so long the price per ride is so low ? :)

:cry: I am near Tampa. Where are you ? I still have a bunch of A123m1 cells. :) They would be the cheapest for 10,000+ miles ? :)

No doubt you could get those A123s to catch fire too ? I bet you could get sla to burn too ? Because many after rusty cells become rusty with water to short out in the rain ?

Cheapest would be a pack made with recycled makita cells from Doctorbass ? http://endless-sphere.com/forums/viewtopic.php?f=9&t=51279 http://endless-sphere.com/forums/viewtopic.php?f=14&t=27707

Back on topic. You are using this right ? http://www.bestekpower.com/444v12spcmbmspcbforli-ionli-polymerbatterypack/PCM-D122.html What will your LVC be set to ?

They are like the frickin devil battery ! Be your friend and buddy for many rides then burn your house down !

I put little 5 amp inline fuses on the balance leads on the packs I build. I don't ever use the balance leads to charge. Just balance and sense the voltage. Some complain the Hyperion will read an error and shut down too quick. It is so picky about sense wire connections.

I know I sure did not.

Real nice fellow too. He met Nancy, came to the house. I am very sad about what happened. He was not a newbee.
