Good ideas for both the jumper-resistor and the clip!

The resistor is almost shorted at the pin header. The clothespin offers no reverse polarity protection. A 2032 cell holder is cheap to buy or can be salvaged from old computer motherboards.

They expire fast.

Hello. The lir 2032 is rated 3.7 volts. Do you think it can be used instead of cr2032 that is rated 3.0 volt in a keyfob for example ? The voltage difference can cause some sort of problem? Thank you.

What is a keyfob? Good question. I suggest you check the device datasheet before connecting a battery with a higher voltage. If you don't have a datasheet or professional test tools, ask the seller or manufacturer...

WONDERFUL

Interesting projects

Nice Idea, man! What is the resistor's value?

I use a 47k resistor, so the charging current is lowered to about 30mah

@@dariocose so basically the less mah the higher the resistor? My second question is why did you solder the resistor to the pin? As it has two pins cant you directly put in the jumper?

@@Mehhh_was_here hi. 1) in the datasheet of tp4056 (or in this video kzread.info/dash/bejne/p5WgrtmSgrWuZrw.html ) there are the tables and formula for choosing the right resistor. In general, the higher the resistance, the lower the charging current. 2) I have no idea why I soldered the resistor on the pins 😁

Is the best 👍💯👍💯👍💯

thank you bro!

that resistor just slow down the current but the voltage is 4.2 still dangerous

how about a ML2032 charger

I read a few articles. I don't think you can use the same charger for lir and ml. "They have completely different chemistries so they have completely different charging voltages and profiles." - electronics.stackexchange.com/questions/533265/protection-and-charging-circuit-for-lir2032-or-ml2032-battery - www.reddit.com/r/dreamcast/comments/g1atiq/lir2032_vs_ml2032/ you can try a charger like s.click.aliexpress.com/e/_DkRpijx or this circuit seems suitable and adjustable in voltage and current s.click.aliexpress.com/e/_Dne8NMD

LIr 2032 have higher voltage, but you can add a diode in series on output + terminal for drop the V. and charge ML2032 ?

I thought they were single use

Only the LIR2032 are rechargeable
