4. Comparison of user measured data
| test items | LiPo 3S | Li-ion 4S | NMH |
|---|---|---|---|
| 0-60km/h acceleration | 2.8 seconds | 3.5 seconds | 5.2 seconds |
| Top speed (km/h) | 78 | 65 | 45 |
| Charging time | 1 hour | 2.5 hours | 4 hours |
5. Precautions when purchasing
1.size match: The standard size of the KM short-card battery compartment is 138×46×38mm. Extra large-capacity batteries may need to be modified.
2.temperature control: It is recommended to use a cooling fan for high-discharge batteries, and the temperature needs to be monitored for use in summer.
3.Charging safety: LiPo batteries must use a balancing charger to avoid overcharge and overdischarge.
4.budget allocation: The cycle life of high-end battery packs (about 800 yuan) can reach 300 times, which is twice that of low-end batteries.
6. Expert advice
According to the latest guidelines of the International RC Association: it is recommended to choose 1/8 scale models such as KM short truckMinimum 5000mAh capacityandContinuous discharge above 30Cof battery. For users who often perform somersault stunts, instantaneous discharge capability is more important than capacity.
