GROUPBUY: 8pcs Samsung 35E BUTTON TOP for the BLF GT

Interested, hopefully ship to Australia

I had the same thoughts as you. A sepic (buck/boost) regulator would have been the better choice, but also increased cost, complexity… and I suspect, introduced a myriad of unforeseen problems for the manufacturer. The limitations of maintaining regulation with the GT buck driver has also been discussed in the GT thread. You are correct, that the best performance of the GT will be realized while using cells that can maintain the highest voltage throughout the discharge curve. Keep in mind, that the discharge amps while using 8 cells in the GT will be about 1.5A per cell at max power. With that in mid, the Samsung 35E does a good job maintaining a high voltage while carrying a 1.5A load, especially for a 4.2V cell. Considering the availability of 4.30V and 4.35V cells, I was skeptical until I compared them against dozens of other cells using HKJ’s discharge comparator. Unless I missed something, the Samsung 35E is the better choice (and does not require a special charger to recharge them to max capacity).

Compare several 4.2V 18650 cells at the 1A and 2A discharge rates and see if you can find a cell that does an overall better job than the 35E.

Also keep in mind that our eyes perceive light logarithmically, and probably wont be able to detect lumen variations in the field while using any of the top quality cells that most of us already use.

Please PM price quote when available and add me to the list. Thank you.

I am interested
If they are shipped to Uruguay, I will place two orders

Interested if they ship to Finland.

Interested!

Does price apply to shipping to the Philippines?

any chance they will ship to Canada?

Let me know if you have any way of shipping to South Africa.

8 cells around $40 shipped?

Interested

Interested – i used the form.

I am in the same boat as my two fellow Aussie mates here. Not hopeful but I have put in my details too. :smiley:

Interested. Entered my email in the form.

Interested. Do you ship to New Zealand?

Interested please Max

interested and also filled out form, thanks M4D M4X.

Interested and filled out the form already.

I already signed up for the unprotected BT 35E, but i would also be interested in protected ones if you can get us a deal on them too.

Interested if shipped to Brazil

i was told shipping to most countries...
