Batteries How to charge lipo battery that has only power cable, Need some details

[maddy23285]

Hi,

I ordered for V913 3 x Flybar and 8 x Tail Blades from aliexpress.com but, they sent me wrong parcel of 5 Lipo batteries. These batteries has only power wires. No balance charge cable is attached. I think these are batteries made for some quadcopter or heli. I don't know exactly where and how I can use these batteries.

Please check the images for more clearification.





Anyone who knows something about this batteries please reply with the details about implementation and charging these batteries.

Thanks

I wouldn't attempt it... they sent you the wrong product, contact them and request that they correct their mistake.

Thanks for reply Randy,

I raised a dispute, the seller has refunded full amount within a hour and he said there is no need to return these batteries as well.

Now I want to know, how can I use these batteries.

I don't to how to charge it. It does not has any balance charging cable.

These batteries looks similar to batteries used in some syma and husban helis.

Really without the balance lead you can't use them. Well you could its just that they will go out of balance after a few cycles.

I am not suggesting you do this but if you really want to or have to you could separate the cells to 1s and use them that way. I don't recommend this because of the potential for shorting the packs.

Then it will depend on your charger and if it supports charging a lipo in that manner... If it does ( read the manual to find out )... I'd recommend setting it to a low amperage setting, probably about 0.5C or less

What charger do you have?
Depending on that answer, you just need to make a charge cable with the opposite end to the one on the battery.
Set the charger to 0.25A, 2cells and charge away

Thanks for reply guys,

Here are few chargers that I have.

WlToys V913 Heli Charger (for 7.4V battery)




VLToys V911 heli battery charger (for 3.7v battery)



Imax B3 compact charger for 1~3 Cell battery




Imax B6 Mini Charger



Can I use anyone of these?

 

[Lee]

Yes you can use the Imax B6.
Just need the charge cable to connect to those batteries, or change the connectors on the batteries to ones you want to use.

OK, Thanks Lee

I would be tempted to cut them open and put balance leads on them but if you do that I accept no responsibility if you burn your house down or blow yourself up.

More than likely, they are not going to have the circuitry for balance leads. You can however, take them apart (ahem, Rc-Help does not support or endorse you trying to blow your hands off by opening up a rechargable pack of c4. We assume no responsibility for what you may or may not do with these batteries) and solder them up as 1s packs. meaning no balance. All batteries have a positive and negative. But I wouldn't do it for safety reasons.

 

[Stambo]

There is no circuitry for balance leads, all you need is a neg same as the neg power lead, a pos, same as the pos power lead and a third wire from where the 2 cells join.
Use a balance lead extension and jobs done.
The circuitry is in the charger.

I still accept no responsibility if you try this and it goes wrong.
