2016-03-13 03:53 <arossdotme> for an rc battery lipo 4s 20ah 10C. should i get this protection board www.aliexpress.com/item/4S-20A-11-1V-li-ion-BMS-PCM-battery-protection-board-bms-pcm-for-lithium-LicoO2/32388217872.html?ws_ab_test=searchweb201556_3,searchweb201644_4_10001_10002_10005_301_10006_10003_10004_62,searchweb201560_8,searchweb1451318400_6150 or...
2016-03-13 03:53 <arossdotme> this one that costs a bit more:

2016-03-13 03:54 <arossdotme> looks like theres some differences. not sure what they mean
2016-03-13 04:00 <arossdotme> i dont think i need balancing build in? as i will only be using a balancing charger. or does the balancing circuity help keep the cells balanced when discharged? :/

2016-03-13 10:30 <DocScrutinizer05> arossdotme: yes, balancing also on discharge helps a lot, though in this case it's more the per-cell undervoltage monitor + cutout
2016-03-13 10:30 <DocScrutinizer05> that does the trick
2016-03-13 10:31 <DocScrutinizer05> the balancing current is too low to actually help during high load discharge
2016-03-13 10:31 <DocScrutinizer05> in your last link you posted

2016-03-13 16:11 <wpwrak> now, let's see if i can get this voltage regulation redesign done. that stuff's been sitting on my desktop for the better part of three weeks by now. and each time i think i've covered everything i find something's i've overlooked :(

2016-03-13 17:11 <arossdotme> DocScrutinizer05, thanks muchly, feel ive been enlightened some more :)
2016-03-13 17:14 <arossdotme> my discharge load is a few amps. 3-4A for my audio power amp, 3A for my rgb led light panel, 2-3or4?idk for my netbook

2016-03-13 17:25 <eintopf> my monitor still works fine

2016-03-13 19:19 <wpwrak> eintopf: let's hope that it'll have many good years of service life left :)
2016-03-13 19:22 <eintopf> wpwrak: I also try to working on short address stuff
2016-03-13 19:22 <eintopf> it worksa
2016-03-13 19:22 <eintopf> but I did everywhere a /* TODO */ in ipv6 neighbor discovery...
2016-03-13 19:23 <eintopf> because it's not easy to make stuff there which is very specific to link-layer handling in a global upper layer implementation
2016-03-13 19:23 <eintopf> but I think for 6lowpan we need an own neighbor discovery implementation anyway
2016-03-13 19:24 <eintopf> but this is for future, first prepare the neighbor layer (which is used by arp/ipv6 neighbor discovery/ ALSO ATM YEAH!/etc...) to give me the neighbour_priv pointer when calling dev_hard_header
2016-03-13 19:24 <eintopf> and I hope they will accept it mainline
2016-03-13 19:25 <eintopf> possible othersolution would be 1. backup skb->cb, 2. put pointer into skb->cb, 3. call dev_hard_header, 4. restore skb->cb
2016-03-13 19:26 <eintopf> but this is bullshit
2016-03-13 19:26 <wpwrak> yeah, sounds very ugly
2016-03-13 19:26 <eintopf> I want it as parameter for dev_hard_header
2016-03-13 19:26 <eintopf> of course const
2016-03-13 19:29 <eintopf> but I first want to make some use-case for short address handling in neighbor discovery cache of ipv6, then all people understands why I need that
2016-03-13 20:37 <eintopf> meh, I watched alien at the tv while eating
2016-03-13 20:37 <eintopf> the alien blobs out of the guy
