Litespeed, Alex and Cowardly Duck
No idea where located in the world.
That would be too easy...the Android "device" is an old tablet that does not have a camera or a microphone...and that isn't the only issue. EM3ev wants me to install software on my computer that gives them access to it so they can remotely access the BMS. Since the computer is not owned by me personally, installing unapproved software is not an option. Wrote back to EM3ev offering several options to get the battery repaired as well as an option of credit towards a future battery purchase.
Yes, first class batteries from Justin.Bullfrog wrote: ↑Apr 26 2020 5:34amHas anybody bought a battery from Grin Tech?
I know they are not the subject of this thread but they are what I would consider one of the major three suppliers at least for North America . I sure do like Justin and he is always super helpful. Maybe we have been missing out by not utilizing Grin???
I am waiting for somebody to produce a 20s battery capable of 50A continuous and with at least 1,000 Ah. Probably go with EM3ev, Luna, or Grin...whoever makes one first .
Lol, what does that mean? I had a ridiculous ordeal with Luna and the people I spoke to on the phone weren't sober. Recreational drugs are great but probably not for people trying to be professional at work. To clarify, I don't consider acid a recreational drug and I don't actually think they were on acid. Just stoned and stupid. Although Eric has definitely done some acid in his time and I'm not sure the results are what one would want.
Thanks fechter...I'll give the low amperage charging a try.fechter wrote: ↑Jul 31 2020 9:23amIf you have a way to charge the pack at a current that is less than the balancing shunt current (typically 50mA or so), you could let it go for a long time and it should eventually bring up the low cell groups. If you can access the cell connections at the BMS, it would be faster to manually charge the low group.
I ordered some stuff from Luna (California USA) and I figured in the hidden cost of $44cdn FedEx Ground fee for international shipping to Canada from USA. I just wanted it sooner then months later (CycloneTW - China)
