Core parameters of CROSSRC EMO X5 Leopard 3S 5200mAh battery:
- Type: Lithium polymer (Li-Po)
- Nominal voltage: 3S (11.1V, fully charged about 12.6V)
- Capacity: 5200mAh
- Discharge rate: 50C (instantaneous maximum discharge current: 5200mAh × 50 = 260A)
- Dimensions: about 138mm × 47mm × 25mm (need to confirm compatibility with EMO X5 battery compartment)
- Plug: T-Plug (need to match the original car interface, some versions may require an adapter cable)


Performance of CROSSRC EMO X5 Leopard 3S 5200mAh battery:
- Power output: Compared with 6S battery, 3S power drops by about 40%-50%, and climbing angle and acceleration performance are weakened.
- Temperature control performance: low voltage + high discharge rate design, long-term high-load use may still cause heat (it is recommended to monitor the temperature).
- Balance charging: A Li-Po balance charger that supports 3S is required, and the recommended full voltage is 11.4V (single cell 3.8V).

How to use the CROSSRC EMO X5 Leopard 3S 5200mAh battery?
1. Prioritize low-speed cruising, light off-road or indoor venues.
2. Avoid using it in complex climbing terrain (easily trigger battery protection or insufficient power).
3. Use a genuine balance charger and set the charging rate ≤5C (recommended 2C).
4. The storage voltage is recommended to be 3.85V per cell (total voltage 11.55V), and long-term storage requires regular recharging.
5. If you pursue power, you can upgrade to Leopard 6S 5200mAh (need to confirm that ESC supports 6S).
6. If you need to balance performance and battery life, you can choose 4S 5200mAh (gear ratio or motor parameters need to be adjusted).
