Basically it solves the problem of having to repeatedly swap out disposable batteries or deal with inconsistent voltge drops in medium-draw gear—things like portable LED arrays or small medical carts where you need steady 11.1V but not the full current of a high-rate pack.
What it does is handle those loads without overheating or sagging too fast, which is a common headache with cheaper lithium packs that claim medium discharge but can't sustain it past the first few minutes, though honestly the 0.2C continuous rating means you're not pushing it hard.
The 5.2Ah capacity gives you about 57.7 watt-hours in a package that's 39×56×68mm and only 270g—give or take the 5g tolerance—and the 3S2P config means you get parallel redundancy so if one cell group weakens, you don't lose whole pack.
We usually have stock on these (CE, RoHS, and UL-certified) but lead times can stretch to 20 days or so when orders hit 500 units or more—the 3% self-discharge per month is actually better than most 18650 packs we've handled, by the way, so storage isn't a headache.
At roughly 500 to 1000 cycles depending on how you treat them—keep charge tempearture between 0°C and 45°C, discharge from -20°C up to 60°C—you'll see the capacty fade earlier if you're regularly pulling near the peak 15.6A for the 3C bursts, but most buyers go with the 5.2Ah continuous setup for steady-state lighting and it holds up fine.
Anyway, one thing I'll mention is that this pack isn't great for high-drain vape mods or power tools where you need sustained 50A or more—the 18650 cells inside are medium-rate, not the high-drain Samsung 30Q types—but for anything in the 1 to 5 amp continuous range, it's reliabel workhorse we've shipped thousands of.
We usually start at 100 units for custom orders, but we can do smaller quantities for standard specs like this one—just reach out to confirm.
Yes, we include copies of our CE, RoHS, and UL certifications with every batch. Just let us know in the order notes.
For stock orders, it's about 7–10 business days. Custom labeling or packaging might add 3–5 days.
That's the standard continuous rate, but the pack can handle bursts up to 15.6A for short periods. For steady use beyond 1.04A, let's talk about your application.
Keep it at 40–60% charge in a cool, dry place around 15–25°C. We also recommend charging it every 3–6 months to avoid deep discharge.
