How to Choose the Best Battery for Traxxas Slash 4×4
Voltage and Cell Configuration
Voltage determines your Slash 4×4’s top speed and acceleration. A 2S battery provides 7.4V, 3S delivers 11.1V, and 4S offers 14.8V.
Higher voltage means faster speeds but requires compatible electronics. Check your ESC specifications before upgrading to 3S or 4S batteries.
Capacity and Runtime
Battery capacity measured in mAh directly affects how long you can drive. Higher capacity batteries like 5200mAh or 6500mAh provide longer run times.
Balance capacity with weight since larger batteries add mass. Consider your typical driving sessions when selecting capacity.
Discharge Rate (C Rating)
The C rating indicates how quickly a battery can deliver power. A 50C battery provides steady performance while 80C or higher handles extreme demands.
Higher discharge rates prevent voltage sag under load. Match the C rating to your driving style and motor requirements.
Battery Chemistry
LiPo batteries offer better performance and lighter weight than NiMH. However, LiPo requires more careful handling and storage procedures.
NiMH batteries are more forgiving for beginners but heavier and less powerful. Choose based on your experience level and performance needs.
Connector Type and Compatibility
Ensure the battery connector matches your Slash 4×4’s ESC. Common types include Traxxas plugs, T connectors, and XT60.
Some batteries include multiple connectors or adapters for versatility. Verify physical dimensions to ensure proper fit in the battery compartment.
Frequently Asked Questions
Can I use a 3S battery in my Traxxas Slash 4×4?
Yes, if you have the VXL brushless system, which is designed for 3S LiPo batteries. The standard brushed system requires an ESC upgrade to safely handle 3S voltage.
How long does a 5000mAh battery last in a Slash 4×4?
Runtime typically ranges from 15-30 minutes depending on driving style, terrain, and motor system. Aggressive driving and brushless motors drain batteries faster than casual cruising.
Do I need a special charger for LiPo batteries?
Yes, LiPo batteries require a balance charger designed specifically for lithium polymer chemistry. These chargers balance individual cells and prevent overcharging damage.
What’s the difference between 50C and 80C discharge rates?
Higher C ratings deliver more current on demand, preventing voltage sag during acceleration. An 80C battery provides better performance under heavy loads compared to 50C.
Can I use two batteries in my Slash 4×4 at once?
Not without special wiring modifications. The Slash 4×4 is designed for single battery operation, but you can keep spare batteries for extended driving sessions.
Final Thoughts
The Gens ace 5000mAh 3S LiPo offers the best overall performance for most Slash 4×4 VXL owners with its perfect balance of power and runtime.
Consider your driving style, budget, and electronics compatibility when choosing. Match voltage to your ESC capabilities and select capacity based on desired runtime.
Start with a 2S battery if you’re new to RC, then upgrade to 3S as you gain experience and confidence.
