Only if you rip out the charging port interface as well, seeing how the battery only has a motherboard connector.
But if the charging circuitry sits on the motherboard, you might be out of luck.

Hi.
I bought a Himalaya from ebay that cannot be charged through mains charger...
Although it can be charged through the usb cable..
I tried to charge it with its cradle connected to the wall charger and it's not charging. If i remove the battery and put it on the cradle it's charging(the battery only). Also, i tried my blueangel's wall charger and it's also not working with this himalaya. (it should?..)
So...now i'm charging the device through usb...either with the cradle or just a capable usb cable.
I think that there's a problem with the connector of the device...but i wonder why it's charging on usb and not charging on mains charger.
The best solution that i can imagine is to open it...measure the pins with a multimeter and then short-circuit the usb charging pin with the 'faulty' one...
Any other ideas?

Hi.
Thanks for the reply. I have already tried to alter the connections on the charger. I short-circuited pin 22 with pin 13 and it was charging. Altough...when i tried to solder the short-cirtuit i destroyed charger's connector So i'm afraid to solder something on the 2020's side.
Is there a way or special soldering iron for such jobs?.....
My conclusion about himalaya's charging system is that it's charging from pin 13 when connected on usb but it's charging from pins 20,21,22( not sure) when connected on a wall charger.
For now, i'm using a usb wall charger by connecting the usb cable on it.
dear nicktgr15
Its very interesting.
Could you please give me screenshoot of that PIN connect to wall charger ? Which PIN in the himalaya mainboard .. connect to what Female PIN on wall charger ?
My Himalaya 22 pin choped so can not possible to charge on spot.
I can only charge the battery by remove the battery and charge on seperate charger.
So when my himalaya power is over I have to take the battery out on it and charge it on the general charger...
Thanks anyway.
Hi everyone. I bought Niki the other day on ebay with broken screen. It is fixed now but notice that AS does not work nor I can charge the battery. The USB connector is fine and it is not de-soldered. Forgot to mentioned it is running custom OS from here and is unlocked.
Wonder if anybody has any suggestion what it could be?
Thanks
if charger is plugged in without the battery I get 2.2 V between pin 1 vdc and pin 4 on bat connectors. Does that mean it should be charging?
ok....does anybody know if I can charge the battery direct to selectable voltabe PS? guess I am asking what is the charging voltage?
anyone......
Can someone please take the battery out and measure out pin 1 and 4 accross while charger plugged in. Need to know what is the charging voltage. My shows 2.2 V which is not enough. Guess second question is has somebody managed to find what is causing this fault. Must be a common fault as it use to get very hot during the charge.
anybody? is there any electronic schematics for power circuit for this model?
Just measured it. On my NIKI100 it shows 2.80V on the outer pins when I dont have a battery connected but having the USB connected. When the battery is in and has USB connected it is charging with 3.95V.
hello...help the battery does not charge....with 8 months ...why?
I have to buy a new one?
what battery are you trying to charge? does it just not charge at all? does the charging light come on??
Is it the battery not charging or is it a problem with the charger or the cable so no charging light at all?
have you tried an other cable and another charger?
e.g. other cable connected to the laptop?
So i have this original n7100 battery that i want to find a use for, and my gf has a low budget samsung phone(and i have a spare charger for her phone) that is always out of battery, and i was thinking if i could just cut the cord of the charger and connect to the spare battery, the output of the charger is 4.75v 0.55A, the spare battery is 3.8v 3.8A, her phone battery is 3.7v and 0.7A
Is it possible or would it be easyer to just mod her phone to use the spare battery to act as the main power source? Then would it be possible to get a transistor to act as battery switcher so she could just unplug the spare battery (i would just create a connection port on her phone)
Saturday night and i can't go out so i really need a project

sory, that text is a little bit confusing for me, but you have to check correct volateg and amparage, lowering voltage and amp, is easy, the reverse is a little harder.
try this way
hi,
use otg adapter and connect to the note. then take charge/data cable and connect the cable to the adapter and the other end with yours girlfriend phone. under 5V there is no worry. maybe you unplugg your phone and there ´s still the charge sign. then u have to restart your phone. but i dont think that will happen.
cheers
:laugh: Maybe Your Rom make Pin drain so fast

Yes, this is entirely possible. But you're not going to find someone who can say how much work it will be to make it happen unless they've done it themselves. These lithium batteries need control circuitry to charge and discharge correctly. I'd try to use the battery to drive something else (like an LED and resistor) first to see if you can get it to work. If there's not built-in circuitry to prevent that, it my work for the phone too.
I’ve looking at adding a second charge port so I can use OTG and charge, tried lots of different OTG cables, hubs, hubs with switches but nothing works.
Today I’ve tried wiring in a TP4056 charge board but it’s not charging my battery even though the charge light is on
Can anyone help with this
Red + battery power out
Black - neural power out
White + battery
Green - battery
Could anyone please help with why I can’t change battery, it’s still charging with the original change port but not with the PT charge board
Why do you say it's not working? Are you expecting the charging indicator to work?
If you wired an external charging board directly to your battery, Android is probably not going to recognize your battery is actually charging

Hi
Yes that what I thought, I left screen turned on and plug-in to the PT charge board and the battery lost power so I guess it’s not charging
It’s still charges fine with the original port

You can bypass the battery protection module. Connect the charging module to 2 battery packs (Use B + and B - connection, ignore the connection OUT + and OUT - ).
Battery pack -> charging module
Battery pack -> battery protection module -> motherboard
You can use multimeter (select DC voltage) to measure the voltage.

Hi
I’ve done as you have suggested but it still doesn’t change, I wondering if the charge module has a large enough output to charge the battery, Fire HD 10 3.8v 6300mAh
I think the module is input 5v output 1A

Were you able to get this working? I am going to try to do the same tonight. I came across your post and it has me worried that it won't work. 5W should be enough power to keep the battery charged. I believe most USB 2.0 cords only charge at 5V 0.5A, or 2.5W.
Hi
Sorry for not replying earlier
No not got it working, have you had any luck?
I would love to get this sorted
I believe the powerboost 1000c that I have is faulty. I wired it up last night and it is showing the battery as full, even though it is at 3.7V. I have ordered two other types of lipo charging modules to try. One is a 2A charger, so I can rule out that 1A is not enough. They should be here this weekend.
The 1A charging module arrived today. It is working, but the battery is charging very slowly. I realized it is the same TP4056 that you mentioned in your original post. Maybe yours was defective, or it isn't enough power to charge the battery and run the dongle. I did modify my otg cable, adding in a usb male connector to power the dongle from another source. I haven't tried a normal cable with the charging module yet.
I should get the 2A charging module and a new otg cable tomorrow. I will post my results after some testing.

Very interesting
Thanks for the update
Any news with the other board?
