Talk:XO LiFePO4 Recovery Procedure
dont know where i get ot here but ok ill try:
well folks, just after a glance at the vast detail of the recovery procedure guys i suppose i am right to post right HERE:
what i did:
i opened the lid of the batterie pack and after a while i did it:
i changed the two lifepo4 for 4 standard liion 18650
and ok, i runs...
cant well tell -normally the capacity should be DOUBLE!!
can someone of the hard/software guys enlighten us what about "smart batterie" status of the xo1 <-> batteries
is there ANY??
i prefered to SWITCH SUCH COMPLETELY OFF -if POSSIBLE
(and yes i know i then have to watch ot about the voltage etc.. not to talk about danger explosion, fires ... blah blah...)
but the advantage is:
more power, use of ANY used batteries from scrap, as there are a lot out there worldwide...!!!
if you want i can make pics of my mod... allows single batterie change in a second, lid closes well, these two mechanisms are well suited for!!!
and: yes sirs, did same at my eeepc, too: works, too!! , thomas@biopilze.de
VERY bad idea!
The XO charging system is not designed to charge the Li Ion batteries found in most laptops. Not only will it not effectively charge Li cobalt batteries its extremely dangerous. You have created an extreme safety hazard for yourself. Mis-charging lithum colbalt batteries will result in explosion.
(reasked by thomas@biopilze.de: please explain: what is the problem? out of my experience with older 18650s LiIon-batteries seem to withstand even higher voltages (happened about 4.4v) without problems (yet)...
and: i had only put these older 18650-s loosely into the batterie-slot in the xo, this results in bad contact -so NORMALLY the cells just WONT CHARGE completely... -SO WHERE IS THE D A N G E R man??? -CANT SEE it YET!!!, thomas)
It's not the voltage. The charging circuitry will over-charge a lithium-ion battery. Imagine trying to charge a NiMH with your EEE pc: they're different chemistries
i've an other problem
my battery did not charge full, so when i try to run bat-recover to fix that, i get the response: no response from battery see-bstate responde: ff and xo hangs up watch-battery gives "normal" information...
any ideas?
Bizarre Results
I'm having some issues with my battery, and I'm not clear on whether the recommendations on this page apply to me or not. My xo shuts down when the battery claims to be at about 40%. I hoped that resetting it with batman's bat-set-low would help, but that appears to have made no difference.
I was hoping to shine some light on my problem, but olpc-pwr-log is giving me weird readings for net ACR. I was under the impression from this page that net ACR shouldn't be in numbers over 3,000, but it changes by thousands per reading! I'm figuring that, for some reason, I'm getting net ACR in units other than those described in this page, but I don't know what units. Can anyone shine some light on this?
