Each configuration delivers high energy density and high usable capacity in a low-weight, compact pouch-cell platform, with modular 2S–6S voltage options from 6.8 V to 20.4 V. It is engineered for US-based UAV and agricultural drone manufacturers, robotics and AMR builders, and defense programs that need a long endurance drone battery pack without adding airframe mass.\u003c\/p\u003e\n\u003ch2\u003eWhat is silicon-anode chemistry?\u003c\/h2\u003e\n\u003cp\u003eThese are lithium-ion cells. The difference is the anode: conventional lithium-ion uses graphite, while these cells replace it with silicon. At the anode-material level, silicon stores roughly 10× more lithium per gram than graphite (on the order of ~3,400 mAh\/g of active material versus ~355 mAh\/g for graphite), so more energy fits in the same weight and volume. This is a property of the anode material's lithium-storage capacity, not a claim that the finished pack has 10× the energy of a conventional pack. In practical terms, a 6S silicon anode lithium ion battery here carries ~225 Wh in a weight class where a conventional 6S 5000 mAh LiPo carries ~111 Wh — roughly double the stored energy for endurance-oriented missions. Cells use an NMC cathode in pouch format, with a 4.20 V\/cell maximum charge and a 2.50 V\/cell cutoff.\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable border=\"1\" cellpadding=\"8\" cellspacing=\"0\" style=\"border-collapse: collapse; width: 100%;\"\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eField\u003c\/th\u003e\n\u003cth\u003e2S\u003c\/th\u003e\n\u003cth\u003e3S\u003c\/th\u003e\n\u003cth\u003e4S\u003c\/th\u003e\n\u003cth\u003e6S\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eConfiguration\u003c\/td\u003e\n\u003ctd\u003e2S1P\u003c\/td\u003e\n\u003ctd\u003e3S1P\u003c\/td\u003e\n\u003ctd\u003e4S1P\u003c\/td\u003e\n\u003ctd\u003e6S1P\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNominal voltage\u003c\/td\u003e\n\u003ctd\u003e6.8 V\u003c\/td\u003e\n\u003ctd\u003e10.2 V\u003c\/td\u003e\n\u003ctd\u003e13.6 V\u003c\/td\u003e\n\u003ctd\u003e20.4 V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum charge voltage\u003c\/td\u003e\n\u003ctd\u003e8.4 V\u003c\/td\u003e\n\u003ctd\u003e12.6 V\u003c\/td\u003e\n\u003ctd\u003e16.8 V\u003c\/td\u003e\n\u003ctd\u003e25.2 V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNominal capacity\u003c\/td\u003e\n\u003ctd\u003e11.05 Ah\u003c\/td\u003e\n\u003ctd\u003e11.05 Ah\u003c\/td\u003e\n\u003ctd\u003e11.05 Ah\u003c\/td\u003e\n\u003ctd\u003e11.05 Ah\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNominal energy\u003c\/td\u003e\n\u003ctd\u003e75.1 Wh\u003c\/td\u003e\n\u003ctd\u003e112.7 Wh\u003c\/td\u003e\n\u003ctd\u003e150.3 Wh\u003c\/td\u003e\n\u003ctd\u003e225.4 Wh\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCell chemistry\u003c\/td\u003e\n\u003ctd colspan=\"4\"\u003eSilicon-Anode Lithium-Ion (NMC cathode, pouch format)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCell charge voltage (max)\u003c\/td\u003e\n\u003ctd colspan=\"4\"\u003e4.20 V\/cell\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCell discharge cutoff\u003c\/td\u003e\n\u003ctd colspan=\"4\"\u003e2.50 V\/cell\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDischarge temperature\u003c\/td\u003e\n\u003ctd colspan=\"4\"\u003e−20 °C to +60 °C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCharge temperature\u003c\/td\u003e\n\u003ctd colspan=\"4\"\u003e0 °C to +60 °C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePack BMS\u003c\/td\u003e\n\u003ctd colspan=\"4\"\u003eFinal production specification pending\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePack connector\u003c\/td\u003e\n\u003ctd colspan=\"4\"\u003eFinal production specification pending\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePack continuous output\u003c\/td\u003e\n\u003ctd colspan=\"4\"\u003ePending pack-level validation\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduction status\u003c\/td\u003e\n\u003ctd colspan=\"4\"\u003ePilot \/ engineering evaluation\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e\u003cem\u003eThese are cell-level specifications.

Packs are not yet UN 38.3 certified as finished batteries — prototype\/evaluation units only. Once cells are electrically connected into a 2S\/3S\/4S\/6S pack, that finished design is treated as a battery for UN 38.3 transport purposes and does not inherit the cells' UN 38.3 status. All configurations are lithium-ion batteries and remain regulated for transport; the 3S, 4S, and 6S packs each exceed 100 Wh.
