Samsung 30Q 18650 Battery 4-Pack (USA) $18.58

Samsung 30Q 18650 Battery 4-Pack (USA) $18.58

Here’s a solid deal on some of the best high-capacity 18650 batteries on the market: the Samsung 30Q.  Central Vapors is currently selling them for $5.49 each.  Even better: you can get a bulk discount (extra 5% off) if you buy 4 or more, which should bring the price down to $5.22.  And lastly, you can use coupon code “VAPECHEAP” to get an additional 11% off your entire order.  That works out to just $18.58 total…or $4.64 per battery!  Not bad at all.  In case anyone is wondering, Mooch rates these batteries at 3000mAh / 15A, but you can push them to 20A as long as they stay below 75°C.  You can check out his Bench Test Results HERE.

As always, keep in mind that Central Vapors offers FREE shipping when you spend $50 or more (US orders only).

From Mooch:

The Samsung 30Q datasheet (Section 7.9) mentions operation at 20A. Operation at that level can be done as long as we don’t let the battery get above 75°C, its maximum rated operating temperature.

But this is not a high performance “power” cell, designed for high current. It is a high capacity “energy” cell designed for low to moderate power levels and long running time. At higher current levels the voltage sag and power loss in the cell are huge. Do not exceed 20A.

I am giving this cell a continuous current rating of 15A (about 45W using 3.7V) and a temperature-limited rating of 20A (about 60W if using 3.7V) as long as the cell is never allowed to reach 75°C.

 

Samsung 30Q Batteries (2 Pack) $11.03

samsung 30qFasttech has a two-pack Samsung 30Q batteries for $12.25. But, use the coupon code “RMBBUST” at checkout and the total drops to $11.03 with FREE WORLDWIDE SHIPPING included. Not a bad deal at all on some highly-rated batteries. Just keep in mind that it typically takes up to a month to receive batteries from FastTech. So, I would leave some time for shipping if I were you. With that said… $11.03 shipped is one hard deal to beat.
