Product overview
The CNHL 50D 5000mAh 21700 Li-ion Cell is a rechargeable cylindrical component for custom aircraft battery packs. Its Long Range Series BAK 50D designation includes a 3.6V voltage designation, while its marked capacity is 5000mAh. The 21700 size class is approximately 21mm in diameter and 70mm long; those are format-level dimensions, with exact dimensions varying by cell model. Procurement is at the individual-cell level, with pack integration intended for users who have the necessary knowledge and equipment.
The 50D emphasizes a balance between power capability and stored energy, making it a starting point for long-range FPV, efficient fixed-wing aircraft and UAV battery projects that need current headroom as well as endurance. Custom packs can combine cells in series to increase voltage and in parallel to increase capacity and share load. For 50D cells, a 2P arrangement provides 10000mAh and a 3P arrangement provides 15000mAh. These are pack-configuration capacities rather than the capacity of one supplied cell.
Integration requires appropriate cell matching, interconnections, insulation and wiring. Safe current from a completed 50D pack depends on parallel cell count, wire gauge, connector, interconnections and thermal conditions. Charging equipment and settings must match the cell, and operation must remain within its voltage, current and temperature limits. Exposed terminals require protection against accidental shorts; damaged insulation, abnormal electrical behavior, reverse polarity, physical damage and excessive heat are material handling concerns.
