Samsung INR21700-53G 5300 mAh 15A, original Samsung SDI cell

Samsung INR21700-53G — 5300 mAh 15A, original Samsung SDI cell

Are you looking for a cell with one of the largest capacities in the 21700 format? The Samsung 53G is a proven choice for building battery packs where range matters — electric bikes, scooters, power banks, and energy storage systems.

Why Samsung 53G?

• 5300 mAh capacity — one of the highest values available in the generally accessible 21700 format. More mAh in the pack = greater range without increasing the number of cells.
• Original Samsung SDI cells — manufactured by Samsung SDI, one of the three largest lithium-ion cell manufacturers in the world. No clones, no rebrands.
• Consistent quality batch after batch — industrial cells with full quality control. This is not a market with "declared capacity"; here you get what's on the label.

Technical parameters

What is it suitable for?

• Packs for electric bicycles (e-bike) — 21700 format and high capacity are an ideal combination for 10S, 13S, 14S configurations
• Electric scooters and single-track vehicles
• DIY power banks with high capacity
• Small power UPS and energy storage systems
• Any projects requiring a high-energy cell in a compact format

An energy cell, not a power cell — ideal where range is important, not peak discharge current. If you are building a pack requiring above 10–15A continuous current per cell, ask us about suitable alternatives.

You are buying an original

There are many cells with "sky-high capacity" on the market. The Samsung 53G we offer comes from an authorized Samsung SDI supply chain. We check batches before shipping — we do not deal in fakes or reclaimed cells.
