Haha, Bill, are you there?
I would like 5 or 6.
Flat top can cause poor contact in series, unless you use something conductive between them to ensure stable connection.
Received my six batteries today.
Thank you doingoutdoor.com
Yes, the positive button top stick up enough to use the batteries in series without solder/magnet mods.
I have picture of two of my batteries in series with a multimeter measuring the voltage of the batteries,
but don’t know how to post the picture here.
Interested in 4
edit: got an invoice from bill - paypal sent today 9/25…

I received my batteries. Super quick! Thanks!
Jon got the batteries and post a test video for them, for your reference:
Bump, to a friend’s nice deal.
I have also sent an email requesting 6 batteries if they are still available.

Paypal sent. Thank you for this opportunity!
I am interested in these because I have a Cometa 2016 ordered, but I am slightly confused. Do we order them and send payment to an individual, and then he somehow commands Amazon to ship them? How does that work?
You may post here the number of cells you want, then when Bill reads your post, he will send you a pm for the negotiations to begin.
Or, you may send an email to Bill at bill.qiao@163.com and he will send you a payment request through Paypal and his Amazon store will ship it to you.
Thank you Carman, shipping submitted already.
