Re: Anyone actually used the Boston Power 5300mAh cells?

As Pajda said ...they are definitely not (2) 18650s in one pack. And I have had several buyers using these cells and very happy with them. And yes ....they have gotten more expensive so get' em while you can if you have an interest in them. And still available but they have now increased production ...

Re: Boston Swing 5300 mAh and cell holders. Now ship to Canada

It is official, I can now entertain shipping to Canada by Fedex Ground. Mexico and others are also a possibility. There needs to be a purchase of at least 84 batteries to do this and shipping will be extra as opposed to free shipping in the U.S. for 20 batteries or more. As well, the purchaser will ...

Excellent Matt ...TY! Once again I am glad they are performing for you.

Re: Boston Swing 5300 mAh and cell holders. Free shipping 20 battery U.S. Only

For those of you that might be concerned about these batteries because of soldering issues. There is a solution to this, all you have to do is lift the welded tab on the cathode (positive) side of the battery a small bit with a razor blade and soldering is just like 18650's. The anode side solders v...

Re: Anyone actually used the Boston Power 5300mAh cells?

As far as I know they are readily available ....you can readily find them all over Alibaba, Ali Express etc. Of course it could be that they have a new battery ...as technology marches on but I am not aware of this. In the meantime ...the batteries are what they are stated to be and are new and I ha...

Spot welder recommendation

I have decided on pursuing a spot welder for my battery builds. What are the views about the alternatives for this in the $200 range of options for this need? Kweld? JP Spot Welder? Chinese? Which ones perform on not only nickel but copper. I have studied most of these but would like the end users i...

Re: Boston-Power Swing 5300 Li-ion cell test

Pajda ...have you tried welding or soldering the Swing? I actually got a couple to test and see. I do not have a welder at this time ...but soldering was no problem using a good iron (Hako) flux and Kester 44 solder. I am also not as adept at charging and testing as Thunderheart ....so right now I h...

Re: Boston-Power Swing 5300 Li-ion cell test

Excellent review here on this battery. Has anyone since tried welding any of these? I corresponded with the gent who did that review on Youtube and was told problem soldering them just like 18650s ...so I would think they could be spot welded just as easily.

Nods on that ...and a temporary hold of the information would be OK for me at this time. Basically, it is for an R/C application and I want to see the max current draw during use under load.

Re: Watt Meter/Power Analyser with peak hold

So it holds the peak until another peak is hit or until battery power is taken away? That is all I need at this time ...but I am getting conflicting input regarding this.
