Samsung 30Q or Sanyo/Panny GA?

Working on post count Lexel?

your post looks like it, while mine is giving additional value to the topic

the GA plays out the 30Q up to its rated current

I’m probably just being dense, but I’m not sure what that means. Would you expound?

up to 10A the GA has more voltage drop of about 0.01V per ampere

at 10A the energy from voltage drop is 0.1V more so you loose 0.1Vx 3.1Ah=0.31Ah
at 10 A the Samsung gets 2.8+0.31Ah=3.11Ah to the Sanyos 3.1Ah

voltage and Ah readings are taken from HKJ comparism page

so even under 10A constant load the Sanyo cell contains the same amount of energy as the Samsung
but you cant run a single cell light with 36W constantly because of the big amount of heat

and often you will use the light in lower modes
so the extra capacity of the Sanyo cell has more energy availiable for normal use

so my conclusion is that the GA cell is up to 10A superior to the samsung,
above 10A the Sanyo cell is beyond its rating and would contain less energy because of the voltage drop

I real life you’ll probably not notice much, but I do wonder about the following often. Suppose you use turbo mode (10A) let’s say regularly, without giving any numbers to calculate with. What kind of differences in battery life would you get between the GA and 30Q, as the 30Qs are perhaps a bit more “comfortable” with the regular 10A draw, as there is less voltage sag?

where is the best price for protected GA?

If you are in the USA (or Canada) and use the BLF discount code on IMR batteries (15% off purchase) , the GA button top is $5.53 and the flat top is $5.10.

The code is BLF15 (No spacing and case sensitive)

The website is https://www.imrbatteries.com/batteries/…… and the code is good site wide for anything they have.

If interested in the thread I started on this it is HERE

where is the best price for protected GA?

Not sure, but here are a couple of places for protected…………

$7.95 / BT

$9.95 / BT

Then if you can go the unprotected route…………

$6.00 / FT

$6.50 / BT

$5.99 / FT

$7.49 / BT

BT = Button Top
FT = Flat Top

By the way, the ‘GA’ Flat Tops will work in series. Personally, the unprotected flat tops are what I am buying from here out.
For now anyway.

Oh yeah, at IMR there is a 15% discount using the Code… BLF15

I hope this helps.

EDIT: All of the above are reputable vendors right here in the USA. Shipping cost killed the GearBest deals on batteries for me. Even though it has recently been reduced, it is still substantial; especially when the “wait time” is considered since they come from China.

thank you for the links.
