needed a reliabel cell for high-drain portable device we’re scaling up to a few hundred units, couldn’t afford votage sag under load or batch-to-batch variance that kills runtime calculations.
we’ve been burned by cells that claim 3500mAh but test closer to 3100, so we asked for the full discharge curves—this one holds about 3350mAh at 0.5C discharge in our tests, internal resistance is ≤12mΩ which matters for that 15A continuous and 30A peak they list, cycle life is >500 but we usually see 600 or so before it drops to 80%.
it’s basically same cell used in some power tool packs we’ve torn down, but it’s not suited for high-temperature continuous charging above 45°C or storage at full charge for more than a month—drops to 2.75V cutoff which is standerd, but some of our BMSes need a slightly higher cutoff so check that.
they include COA per batch with HPLC traces and internal resistnce scans, we do a random 5% retest here and it’s been within spec for three orders so far.
anyway, lead time is 20 days or so, MOQ is 500 pieces, and we usually have stock but confirm if you need them faster.
For bulk orders, our MOQ is typically 1000 pieces. If you need a smaller trial batch, we can sometimes accommodate that — just reach out to our sales team.
Lead time is usually 15-20 working days after order confirmation and payment. For very large orders over 10,000 units, it might stretch to 25-30 days.
Yes, we supply full copies of CE, RoHS, KC, CTIA, TUV, and CB certifications along with each bulk shipment. Just request them when you place your order.
We can put your brand logo or custom label on the battery wrap, and pack them per your spec — like blister packs or tray inserts. Minimum for custom labeling is 5000 units.
Store them in a cool, dry place at -20°C to 50°C, ideally at about 50% charge. Keep away from direct sunlight and moisture. If stored more than a month, check voltage every 3 months.
