Choosing a LiPo Battery for Axial SCX10 Crawlers
The Axial SCX10 name now covers several generations and a growing number of 1/10 crawler models. From original SCX10 and SCX10 II trail trucks to the expanding SCX10 III lineup, these vehicles can differ substantially in body packaging, chassis configuration, battery position, and available battery space.
That makes battery selection less about finding one universal “SCX10 battery” and more about matching the pack to the particular truck. Voltage, capacity, dimensions, connector type, wire exit, and installed weight all matter when choosing a battery that fits cleanly and keeps the crawler balanced on the trail.
2S vs 3S LiPo for SCX10
2S LiPo remains a practical choice for drivers who prefer smooth throttle control, predictable low-speed response, and relaxed trail driving. It can also make sense on older or customized SCX10 builds where the electronics were selected around a 2S power system.
3S LiPo is widely used when more wheel speed, climbing punch, and throttle headroom are wanted. Many newer SCX10 III configurations support 3S, but the voltage rating of the specific ESC and electronics should always be confirmed rather than assuming every SCX10 build accepts the same battery voltage.
SCX10 III Battery Fitment Varies by Model
One of the most important things to understand about the SCX10 III family is that sharing the same platform name does not mean every model uses the same battery size. A Coyote, Toyota SR5, Jeep CJ-7, Base Camp, Gladiator, or JLU Wrangler can have different usable space around the battery even though each belongs to the SCX10 III family.
Battery position, body clearance, chassis components, strap location, and wire routing can all change the usable footprint. A larger-capacity pack may work well in one model, while another may be better suited to a shorter or more compact battery. For that reason, always compare the battery's length × width × height with the space available in your exact truck.
Battery for the Axial SCX10 III Motobilt Waypoint Jeep JT Gladiator
The 1/10 Axial SCX10 III Motobilt Waypoint Jeep JT Gladiator is a useful example of why model-specific battery information matters. Axial rates this RTR crawler for 2S and 3S LiPo batteries and lists a maximum battery size of 138 × 46 × 35mm. Its adjustable battery mounting system can accommodate both standard and shorty-style packs, giving owners some flexibility to tune battery size and vehicle weight.
Axial's recommended completion setup uses an 11.1V 3S 3200mAh 30C battery with an IC3 connector. That does not mean every battery must be exactly 3200mAh, but any alternative should remain within the available battery space and meet the electrical requirements of the truck.
CNHL batteries equipped with EC3 are particularly relevant here because EC3 and IC3 are physically compatible for the main power connection. An EC3 battery does not provide Spektrum Smart battery data, but it can still be considered as a power option when voltage, dimensions, polarity, and wire clearance are suitable.
EC3 and IC3 Compatibility on SCX10
Several newer Axial crawler setups use IC3 connectors, while many CNHL crawler batteries are available with EC3. EC3 and IC3 are physically compatible for the main battery power connection, making an EC3-equipped pack a practical option for many IC3-equipped vehicles when the battery itself fits correctly.
The important distinction is Smart functionality. A standard EC3 LiPo battery does not contain Spektrum Smart electronics or provide Smart battery data simply because it is connected to an IC3-equipped vehicle.
Using XT60 or EC5 Batteries with an SCX10
An SCX10 battery does not necessarily have to come with EC3 from the factory. If a suitable CNHL pack uses XT60 or EC5, it may still be usable with a properly rated adapter or connector conversion, provided the battery voltage and physical dimensions are appropriate for the truck.
When using an adapter, check polarity, current rating, connector condition, wire clearance, and the extra space required by the adapter and wiring. On tighter crawler chassis, that additional cable length can matter just as much as the battery dimensions themselves.
Popular Axial SCX10 III Models Covered by This Collection
This collection is intended to help owners shopping for batteries across the wider SCX10 platform, including the Axial SCX10, SCX10 II, and current SCX10 III family.
SCX10 III models covered include the 1/10 Axial SCX10 III Jeep CJ-7, 1/10 Axial SCX10 III 1987 Toyota SR5, SCX10 III Coyote, SCX10 III Base Camp, SCX10 III Jeep JT Gladiator, SCX10 III Jeep JLU Wrangler, the new SCX10 III Motobilt Waypoint Jeep JT Gladiator, and SCX10 III Builder's Kit projects.
These trucks share SCX10 platform DNA, but battery fitment should still be checked model by model rather than assuming one pack size fits the entire lineup.
How Much Battery Capacity Do You Need?
There is no single ideal capacity for every SCX10. A higher-capacity pack can extend trail time, but it is usually larger and heavier. A compact battery gives up some runtime in exchange for easier fitment and less weight carried on the chassis.
This difference is especially important across the SCX10 III range. Some models are designed around relatively compact packs, while others provide enough room for larger batteries. The new Motobilt Waypoint, for example, is officially recommended with a 3200mAh 3S pack even though other SCX10 III configurations may commonly use substantially larger capacities.
Instead of choosing capacity first, start with the maximum usable space in your truck. Once the pack fits correctly, choose the capacity that gives the balance between runtime and vehicle weight that suits your type of crawling.
What to Check Before Buying an SCX10 Battery
- Voltage: Confirm whether your specific ESC and power system support 2S, 3S, or both.
- Dimensions: Measure the usable battery area rather than relying only on the SCX10 generation name.
- Connector: Check whether the truck uses EC3, IC3, or another connector and whether an adapter will be required.
- Wire clearance: Make sure the main leads and balance lead can exit without being sharply bent or trapped by the body or chassis.
- Battery retention: Allow enough room for the stock straps or battery mounting system to secure the pack properly.
- Weight: Consider how a larger battery may affect chassis balance, climbing behavior, and overall trail feel.

FAQ
What battery does the Axial SCX10 III Motobilt Waypoint Jeep JT Gladiator use?
Axial lists the Motobilt Waypoint Jeep JT Gladiator as compatible with 2S and 3S LiPo batteries. The stock connector is IC3, the maximum listed battery dimensions are 138 × 46 × 35mm, and Axial's recommended completion battery is an 11.1V 3200mAh 3S 30C IC3 LiPo. The battery mounting system can accommodate standard or shorty packs.
Can I use an EC3 battery in the SCX10 III Motobilt Waypoint?
An EC3 battery can be considered because EC3 and IC3 are physically compatible for power. You still need to confirm that the battery voltage and dimensions are appropriate. A standard EC3 battery will not provide Spektrum Smart battery data.
Do all SCX10 III models use the same battery size?
No. Battery space varies between models such as the Coyote, Toyota SR5, Jeep CJ-7, Base Camp, Jeep Gladiator, JLU Wrangler, and Motobilt Waypoint. Always check the dimensions and battery mounting arrangement of your specific truck.
Can an Axial SCX10 run on 3S?
Many SCX10 and SCX10 III setups can run on 3S, but this depends on the ESC, motor, gearing, and electronics installed in the individual truck. Factory and modified SCX10 builds are not all identical, so confirm the ESC's maximum input voltage before moving from 2S to 3S.
Should I choose 2S or 3S for an SCX10 crawler?
Choose 2S if smooth throttle response and controlled trail driving are the priority. Choose 3S when the truck is rated for it and you want additional wheel speed and climbing punch. Battery fit and vehicle balance are still important regardless of voltage.
Should I choose an EC3 battery or use an XT60 or EC5 battery with an adapter?
A direct EC3 battery is usually the cleanest option for an EC3- or IC3-equipped crawler. An XT60 or EC5 battery can also be considered with a properly rated adapter when its voltage and dimensions are suitable. Check polarity, current rating, wire routing, and the extra space required by the adapter before use.
What capacity LiPo is best for an SCX10?
There is no universal capacity that is best for every SCX10 model. Smaller packs reduce weight and can fit tighter battery areas more easily, while larger packs offer more runtime when the chassis has enough room. Start with confirmed battery dimensions for your exact model, then choose the capacity that best matches your preferred runtime and vehicle balance.
