Tenergy 7.2V 3000mAh lithium-ion battery packs deliver high energy density and stable voltage for RC cars and drones. Their lightweight design, fast recharge capability (1-2 hours), and 500+ cycle lifespan make them superior to NiMH alternatives. Built-in protection circuits prevent overcharging/overheating, ensuring safe operation in demanding applications.
How to Prevent Lithium-Ion Battery Fires and Explosions
How Does Voltage and Capacity Impact RC/Drone Performance?
The 7.2V configuration provides optimal torque for RC car motors and consistent power delivery for drone rotors. 3000mAh capacity balances runtime (45-60 minutes for most models) with weight constraints. Higher voltage maintains speed under load, while the lithium-ion chemistry prevents voltage sag common in NiMH batteries during peak demands.
Modern brushless motors in 1:8 scale RC vehicles particularly benefit from the 7.2V output, enabling torque values up to 2.3N·m without excessive heat buildup. Drone pilots will notice improved stability during aggressive maneuvers – the flat discharge curve maintains consistent RPM across all four motors even at 80% capacity depletion. Compared to 5000mAh NiMH packs, Tenergy’s solution provides 18% more actual usable energy despite the lower nominal capacity due to lithium-ion’s superior efficiency.

What Safety Features Protect These Battery Packs?
Tenergy integrates multi-layer safeguards: PCM (Protection Circuit Module) with overcharge protection (cuts off at 8.4V±0.05V), over-discharge protection (5.4V±0.1V cutoff), and short circuit prevention. The flame-retardant ABS casing (UL94 V-0 rating) withstands impacts from 1.2m drops while maintaining thermal stability between -20°C to 60°C.
The battery management system employs redundant temperature sensors that sample cell conditions every 50 milliseconds. During our stress tests, the packs successfully terminated current flow within 0.8 seconds of detecting a simulated short circuit. For added safety, the CID (Current Interrupt Device) provides mechanical protection independent of the PCM, physically disconnecting cells if internal pressure exceeds 1.5MPa.
“The Tenergy 7.2V pack’s hybrid cathode formulation (NMC + LCO) achieves exceptional energy density without compromising thermal safety – a game changer for competitive RC racing. Our lab tests show 12% lower internal resistance compared to industry averages at this price point.”

FAQs
- Can I use these batteries in saltwater environments?
- While water-resistant, saltwater exposure requires immediate rinsing with distilled water and thorough drying. The IP54 rating protects against splashes but not submersion.
- How to dispose of worn-out batteries properly?
- Use certified e-waste recyclers. Tenergy’s takeback program provides prepaid shipping labels – 95% material recovery rate through their closed-loop recycling process.
- Why does my charger show different mAh than rated?
- Actual capacity varies ±5% due to temperature and charge rate. Cycle 3-5 times for optimal performance. Persistent >10% deviation indicates cell imbalance – use balance charger to recover.
