DOA Zeblaze Blitz with new improved 750maH battery upgrade.
What the hell, why not hahahaha !! Display on all day, no problem!
Seamless upgrade @Jim_Chisholm Gives it a slightly “urban techno-decay” feel!
Yup wait till I strap the Honda Generator on my back and run a couple 12AWG cables up my arm. It’s about coming to that with all these “mobile” devices.
Gawd I love my Seiko Automatics…
very smart idea…maybe smart watch companies in the future can utilize the rubber band for extra batteries beside the antennas
great
Now, lets add Qi charging options and Solar!
Thinking about pulling the Qi receiver out of my old Moto 360 and installing it actually.
I was thinking the same thing for my KW88, but it’s not worth it. The magnetic dock cable works very well.
What smartwatches need is a kinetic charging system like Seiko uses.
Or a super-efficient RF rectifying/charging system for all those signals we’re surrounded by.
Wow, I currently searching battery pack to upgrade my kw88 too. Where did you purchased it?
It’s just a 1S battery that I swiped from my 10 yr old’s Syma drone. A six pack is like $18.00. Search Amazon for Syma battery.
I’ve since moved it to the inside of the strap, fits better, is pretty much invisible and doesn’t interfere or block the embedded antennas. Heck I may put one on both sides.
Couple more pics with battery on inside of strap.
GearBest “offered to replace it” if I pay a $60.00 “handling fee”. Nah…
Hi, Can you show us how to connect the battery to smartwatch pins?
My watch arrived DOA (dead). I opened it up and checked the battery, which wouldn’t charge. It had 0.076V (76 mV) potential.
So I just snipped the battery off the small ribbon connector that leads to the main board and soldered on a couple of leads, which I then ran externally to the battery.
Disassembly of the internals to get at the battery under the main board is very straight-forward. Several small ribbon cables that pop off with your fingernail.
Note I had to make a couple of small notches in the metal back plate for the wires to sit in, else the case would cut through them when I screwed it on and short them out,
LiPOs HATE to be shorted out and can burn pretty dramatically.
Not something you want happening on your wrist.
Freaky battery life with this battery + custom rom. After 8 hrs of fairly heavy use I’m at 94%
Jim, just wondering if you have the ability to charge the defective Lipo with a 10mA current for 30 minutes and then measure the voltage.
I wonder if it recovers to a voltage above 2.4 V.
If so you could step up the current to 100-200mA at that voltage.
You never know.
Yes I tried that with 30mA, pretty much a dead internal short. In my experience any LiPO below 2.4 is permanently damaged and best disposed of.
Next time you open the back and have a clear view of the PCB, make a picture of it for others for future use and entertainment. Like I did with the KW88
Hi @Jim_Chisholm , I had searched and found most of the battery taken from syma drone doesn’t have protection circuit, this means you probably soldered the syma battery to the protection circuit coming from the built in battery. Am I correct? If not, please be very careful of overcharging, it may blow your battery.
@akhmad_kai hi akhmad yes that is correct , I’m using the stock protection circuit. The battery does stop drawing current when full.
At 24 hrs of heavy use and continually playing with it I’m at 55%.
(everything turned on).
can i see this bottom side how do you solder his battery connect to smart watch
