As i already mentioned in tutorial, charge.sh and charge21.sh allow You to charge N900 with bme disabled. May be desired on few cases, where charging-while-hostmode is on top of them.

Differences between charger.sh and charger21.sh were elaborated on tutorial.

Charging with BME disabled. Additional info displayed allows charging to true maximum capacity instead of charging to "Green light is on" which may not be truly full. Charging at different rates to possibly achieve faster recharge.

which one shud i buy? i am from bangladesh..can u plz suggest me one.including the total cost including shipping

Which battery?


As per the first post in this thread:

Also, best choice via quality/price ratio, is christgift. For Dual Scud price, You can already make 2-3 dual christgifts, resulting in total Ah value higher (but with need to switch batteries often). Personally, I did dual-scud (as main battery), and I plan to prepare 1-2 additional dual christgifts, as backup batteries.

I am trying from the first day Estel's info had been published, but I am never able to reach this passage
I mean, for one reason or the other, my VDQ always turn to 0 before approaching the full discharge point.

The setup is a dual Japod (ex DrFrostDK), and I tried many combo from very hard usage to almost no usage at all (and battery duration of 3 days), but always towards the end of the cicle VDQ goes back to 0. When charging, at the green led point, it is 1 so at least this works. Any suggestion to try to understand WHY I am not able to go to learn mode?

If it runs for too long at 6%/0%, it will reject the learn cycle on basis that such a sudden dramatic capacity increase is "impossible".

Solution: follow charging progress (from empty) using "./bq27200.sh 5". When RSOC hits 100%, continue charging 15-30 minutes, then disconnect charger and follow the instructuins posted earlier for calibrating.


On another topic, charge.sh/charge21.sh will normally charge less full than bme. bme does good on kernel-power, charge/charge21 undercharges on kernel-power. bme overcharges/float charges on normal kernel, charge/charge21 does good. Where "good" is manuf recommended charge procedure, which matches what bme did in PR1.0, before a kernel change in PR1.3 inadvertedly affected bme. This change, I think, was reverted in kernel-power.

just been to get a scud battery from aliexpress and it's asking for your mobile number. not over keen at entering it just wondered what everyone else put in the mobile number boxes and has anyone had any dodgy calls or anything?

I put a fake number in. They are nit going to call you. heh.

cheers vi_ that option was my favourite one don't fancy being spammed on my mobile, landline is bad enough!
