charging 1 cell 7.3volt 500mah lipo with iMax B6 charger

I have an iMax B6 charger. I recently bought a Blade 120SR. It uses 1 cell 3.7 volt 500mah lipo batteries. For whatever reason I cannot charge my batteries using my iMax B6 charger.

The charger works for every type of battery I have used with it. But not with the 3.7 batteries. Is it possible to charge 1 cell 3.7v 500mah batteries with the iMax B6 charger? Currently I am using the charger that came with the heli, and it does charge the batteries.

I corrected this listing to correct the voltage of the battery.

Me thinks you need to check your battery label. I think it's a 3.7 volt single cell battery. Not a 7.3 volt.

Yeah, Jack that's correct.

Battery: 1-cell 3.7V 500mAh Lithium Polymer (1.9Wh), 12C

Hi Gpruitt54,

Welcome to the forum.

I have a B6 and a blade 120SR and so does my friend, we have both experienced problems charging the 3.7v batteries, it's not that it doesn't charge, but it doesn't fully charge and the results are inconsistent.

We have both gone to the Celectric 4 port charger with adapters so that we can charge up to 4 at a time no problems since.

Back to the original question, Yes you supposedly can charge 3.7v on the B6 but for what ever reason I can't get it to fully charge consistently.

Yes, I made a mistake. I have the battery in front of my now. Yes, you are right, its a 1 cell 3.7 volt 500mah (1.9 Wh) lipo.

I am trying to charge it with my iMax B6.
The chargers settings are in deed set for the 3.7 specifications.
Charging for 1C, which is 0.5 amps.

I am new at this so forgive my the mistake in what I initially listed about the battery.

While on the subject of 3.7v lipo batteries. Do these batteries need to be discharged after running in the 120sr and before recharging???

Currently, I am using the e-flite charger that come with the Blade 120sr heli. This charger has no discharge capability, as far as I know.

I will look into the EFLITE CELECTRA 4 port CHARGER. Any other recommendations for chargers that will work properly with the 1 cell 3.7 volt lipos???

There is one other thing. From what I can see, the CELECTRA 4 port charger uses those small white balance charge connectors. However, my e-flite batteries has those red (sorry, don't know the name of the connectors). So my batteries will not fit into the CELECTRA charger's ports. So, are there more than one type of CELECTRA 4 port charger with different charging ports?

Thanks!

Hi Gpruitt54,

The adapter you need is "BLH3126 Blade JST-RCY to Ultra Micro Battery Adapter Lead" they are about $4.00 each you can also get others to charge the mCP X batteries.

Horizon have them if you can't get them elsewhere

I charge single cells via my B6 without problem ...

There's no need to connect anything except the main power connector of the battery direct to the main charge out lead.

I even have an adaptor that I can charge individual cells of a multi cell LiPo through the balance plug ... again this is via the main charge out lead of the B6 ... this I use when I find a cell that is down or not charging up properly on balance etc. - revive a cell.
