Axim x51v 3600~ mAh internal battery mod project

--------------------------------

*** project dead for the meanwhile, doing other things:P***

--------------------------------

goal - have a Pocket PC that packs a punch, has a great battery life all while looking sleek and being as inexpensive as possible(not necessarily for myself;-P)... (if it murders iPod touch then thats an extra;))

reasons - 1) avoid needing extended case, 2)the extended batteries at 3600mAh are fugly, 3) have it possibly usable on a aximizer, 4) Have a mp3/mp4 player that is a bit more future proof then consumer units, 5)to avoid people thinking that the axim x51v is a late prototype of the brick phone

rough status

- sticking with Cameron Sino 3600mAh for x51v battery circuit

- battery cells to use chosen! - 2x Cameron Sino 2700mAh for Tungsten C/W / Palm One i705 (3 of 4 cells used)

- battery life estimate needs to be re-assessed(trust no estimateds stated bellow this!)...

--------------------------------

jan05/09 - on my 3rd axim;).... other is not dead yet but just out of commission for now(fried battery meter circuit:P by shorting it by accident, may attempt repair later).... on my 3rd I carefully removed the battery contacts with no damage to the circuit(used micro cutters and soldering iron to melt plastic).....I can now confirmed that the leads that I had specified for HT and ID are accurate.

current conclusion:

-best to use a x51v cameron sino 3600mAh circuit with Tungsten C/W / Palm One i705 cells and use registry tweak to disable battery warnings!:P.... best solution I found and this is probably where my trials end......

I may of found a minor improved method on doing the battery switch mod that involves scratching some of the circuit as to expose a bit of the copper that maybe simpler for people to do the battery door mod(may show pictures later)

feel free to continue where I left off..... next attempt maybe attempt to increase volume on the axim x51v if anything:P

other notes: I bought a Kingston SD4 / 16gb and can confirm that it works fine:-)....... ordered a 32gb too will let everyone know on its arrival, though it has nothing to do with the battery mod....

oct23/08 update --- outdated--- project under revision:P, the circuit board from the 3600mAh cameron sino continued being unstable as far as the battery meter goes,even though it seemed to be almost completely solved.... I'm now trying another battery(2200mAh this time) made by Power Mart or Power Smart from http://www.global-batteries.ca..... will report back if there are any positive results, I will note on a positive the battery had a temperature fuse as a safety which is nice:)

-sometime in 2008 --

Just letting people know that I'm experimenting with putting lithium(lipo) polymer batteries in a Dell Axim as permanently enclosed batteries. I've posted pictures and info of my results....

After hadding killed my first Axim and nearly killing the 2nd one, though luckly being able to find alternative contact points, I've tried modding in a set of 3x lipo batteries.... and have been checking the results

Methods I've used mostly involved using the original circuit board(s) off a dell axim battery attached to lipo cells in parallel.... idea's partly came from the dell axim's 3rd party batteries, the idea that the high mAh batteries such as 3600mAh batteries for the the axim require a “extended” cover that looks fairly ugly and makes the unit fairly bulky, in many cases weighing more.....

I've used tried using and have used: Dell Axim's Original Battery circuit, 3rd party Cameron Sino 3600mAh battery circuit, Generic 2000mAh Tungsten/PalmOne lipo batteries, and Cameron Sino 2700mAh Tungsten/PalmOne lipo batteries

This is a on going project wish me luck!

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! *warning* !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

if anyone is gonna attempt this please be extremely and absolutely careful as lithium ion and lithium polymer batteries are extremely dangerous and can cause a fire or explode if they leak either from a puncture or from overheating, and I will not be held accountable/liable !!!!
