14.4V · 4S · 16800mAh · 20C
Lithium Ion UAV mission pack · 241.9 Wh · 20C continuous / 20C burst
Product nameGenX Ultra 14.4V 16800mAh 20C Premium Lithium Ion Rechargeable Battery
235 Wh/kg — The Reason This Pack Exists
Endurance on a UAV is bought with mass. At 235 Wh/kg this pack carries roughly 1.0× the energy of a conventional UAV LiPo of the same mass — Lithium Ion chemistry.
235 Wh/kg is the published rating. The pack figures divide out at 198 Wh/kg (241.9 Wh ÷ 1,224 g) — its 22.8 V sibling at 447 Wh/kg. Confirm which basis applies before you commit an airframe mass budget; the datasheet states it.
Same Pack, Other Voltage Class
Identical cell, chemistry, footprint and connector — the cell count changes. If your airframe runs a 22.8 V bus, switch here rather than going back to the catalogue.

Questions Buyers Ask On This SKU
01Is the discharge rating 20C or 20C?
20C continuous — 336 A. 20C — 336 A — is the burst figure and appears in the catalogue title. Size ESCs, fusing and harness on the continuous number.
02Why is rated cycle life 800+?
Because it is Lithium Ion at 235 — that energy density is bought with cycle count. Rated pack cycle life on this SKU is 800+. It is an endurance and mission pack, budgeted as a consumable. For high-turnaround flying, ask us to specify a higher-cycle line instead.
03What does ₹9,775 include, and how is GST billed?
₹9,775 is the unit price excluding GST. At 18% that is ₹1,760 tax, ₹11,535 delivered per unit on a GST invoice. Bulk rates apply from 25 units, and OEM pricing is quoted against volume — both come back on the RFQ, not from this page.
04What certification is on record for this pack?
Certification is confirmed per SKU on the quotation, never assumed from the catalogue. Manufacturing and R&D are in Gandhinagar, Gujarat, and the pack is made in India. If a tender names a certification you must hold, ask before raising the PO — we will state exactly what is on record for RKI-6433.
05What charger does 4.2A(1C), CCCV, 4.20 V, 250mA cut-off need?
Standard charge is 4.2A(1C), CCCV, 4.20 V, 250mA cut-off — 70.6 A on a 16.8 Ah pack, over 90 Mins, on a balance-capable charger sized for 4S reading the 2515 Connector harness. Rapid charge on this SKU is 8.4A(2C), CCCV, 4.20 V, 100mA cut-off.
06What is the temperature limit before thermal runaway?
80 °C — do not exceed it. Cell temperature must stay below 80 °C in every condition, on this pack and on every GenX line: charge, discharge, storage and transport. Above 80 °C thermal runaway becomes possible on any lithium chemistry. Treat 80 °C as an abort limit, not a target. If a cell approaches it, land, isolate the pack and report it to us.
07Can I get a different connector or harness length?
Yes. The pack ships with XT90S on the discharge side and a 2515 Connector balance lead. Alternate connectors, cable lengths and OEM harnesses are quoted as custom work — send the airframe interface with your RFQ.
08How fast can you dispatch, and is there a minimum order?
In stock, PAN India. No minimum order — one unit for evaluation is fine. Air freight needs the UN 38.3 test summary; request it with the order.
