I have the Li-Po battery model 804066 and I would like to test it with the digital multimeter but I don’t know how to improvise
I would also like to charge this battery with one of these chargers but I don’t know which adapter to buy
Welcome to the Forum!
Looking at the battery you have it appears to be similar to ones that we sell on our website Polymer Lithium Ion Battery (LiPo) 3.7V 1100mAh | Core Electronics Australia, you should be able to to remove it from the JST housing and probe the exposed metal pins on the connector. As for a charger our Makerverse USB-C LiPo Charger | Core Electronics Australia should be able to charge it via USB C
Is it possible to test with the multimeter without removing this 2-pin connector?
tell me a decent charger model for this battery on Aliexpress
Hi amer
Doesn’t the game console charge the battery??
Cheers Bob
This battery is a backup. Removing the battery from the console runs the risk of damaging it. It’s fragile, so I prefer to charge it outside the console or test it with a multimeter without removing the connector.
Hi gamer
That has not answered the question. If it is as you say a back up it is very likely the console keeps ir charged. It will not be much good if it is flat when it is needed.
You would have to be pretty rough or clumsy to do any damage.
You don’t have to remove the connector (I am assuming by that statement you mean remove the connector from the wires) but you will have to unplug it to gain access to the wires. To do this just plug a couple of small pieces of thin wire into the connector to make contact with the connector contacts and measure with the multimeter.
This is probably not going to tell you much as you will be measuring under zero load but if the measurement is low under these conditions you could say the battery needs charging.
Looking at the pic you might have access to the connector contacts through those little rectangular holes without unplugging it. The sharp points on the meter probes should enable this.

the connector is very small 2 pin JST 1.25mm is it possible to touch the tips of the digital multimeter to analyze the battery? without removing the connector?
the connector is so small that my fingers can’t hold it to pull it from the socket and remove the battery
Bob’s idea of putting thin wire in the connector would be a good way to be able to read the voltage of the battery.
That connector also looks like to should have the pins accessible from the outside to be able to be probed with a multimeter. The contacts would be pretty small but it can be done.
my 804066 battery with 2-pin JST 1.25mm connector has the pins accessible from the outside but I haven’t yet seen if the multimeter tips can touch that region
In the multimeter, what is the correct scale to measure Li-Po 3.7v 3200mah battery without damaging the battery?
If you have a set of multimeter leads that have clips instead of probes then you can clip short pieces of fine wire to the ends and probe with the wires. It may be possible to make up a similar arrangement with something that is available on the workbench.
The correct voltage range will depend on your multimeter but it will be low voltage DC, possibly 20V but any range greater than 5V is safe. If it’s an autoranging multimeter just select DC.
If you are probing with any type of exposed tips be very careful not to let any exposed part of the leads touch. A short could damage the battery (and give you a nasty fright) but worst case it is possible for the battery current to weld parts together and cause a fire or explosion,

I touched two tips of the multimeter to the two silver tips of the battery connector and it read
storing a 3.7v Li-Po battery long term storage at 3.75v voltage in the multimeter is good or bad? Here the temperature is close to 40C when I need to charge again?
For long-term storage of a LiPo battery the recommended voltage should be about 3.8V.
On the device I use, the battery says 48% on the multimeter, the measurement is 3.75v. Will it be necessary to charge it a little again for store?
Hi @gamer87272298,
I would say that is a close enough voltage it is up to you. I’d recommend storing it in a LiPo safety bag somewhere cool.
I can’t quite read the label here but it does appear to say 3.7V so I wouldn’t charge it beyond 3.8V. Overcharging LiPo’s can be quite dangerous.
Hi gamer
After reading that I would respectively suggest reading the instructions that came with your meter and any other material (there is lots) relating multimeter use before you get too much further. It is not too hard and will be rewarding down stream a bit. It is possibly Auto Ranging and Jeffs comments should be followed.
About the only way you could damage the battery by probing it with a multimeter would be to accidentally short the two contacts with the probes.
What did it read?? That bit did not come out in your post. Just a bank line.
Or is this it in another post.
Confusing what you mean here. The multimeter could not read 48%, only the voltage.
I strongly suspect you have put the comma in the wrong place and completely changed what you actually meant. If you put the comma between “48%” and “on the” it would make more sense. Then it would read
“On the device I use, the battery says 48%, on the multimeter the measurement is 3.75v.”
Quite a bit different with the comma moved.
Attention to detail and accuracy makes all the difference when trying to offer solutions and advice remotely. Remember YOU know what you mean. WE don’t, “we” can only read what you submit.
Cheers and study up on Digital Multimeter Use.

3.75v is good or bad for long term storage Li-Po battery? Is it necessary to go up to 3.80v or can it be maintained?
Hi gamer
3.7V is the nominal voltage for this battery so it should be OK. This is only my opinion. If you really want to make sure try putting “LiPo battery” into your browser. There will be plenty of quality information from battery manufacturers there. There will also be plenty of other information and some of questionable quality so I would take more notice from the people who make the things as a preference.
Cheers Bob
long term storage battery in 3.75v is good or bad voltage for store?
Hi Gamer,
I’d say that would be fine. Just make sure it is stored safely.
Hi gamer
Why can’t you do what I suggested above, refer to a manufacturer’s information.
Cheers Bob
