Quick Fit Check
The CNHL MiniStar 900mAh 7.4V 2S 30C LiPo Battery with PH2.0 & JST Connectors is a higher-capacity battery option for compatible Axial SCX24 crawlers, small-scale RC vehicles and other lightweight 2S models. Its 900mAh capacity provides approximately 2.57 times the nominal capacity of the common 350mAh SCX24 battery.
Each battery measures 55 × 30 × 12mm (L × W × H) and weighs approximately 39g. Before ordering, verify the battery mount, PH2.0 connector polarity, wire clearance and added weight. More capacity can increase runtime, but it does not guarantee a specific number of driving minutes or a direct fit in every SCX24 configuration.

More Capacity for Axial SCX24 Crawlers
The common Axial SCX24 stock battery is a 350mAh 7.4V 2S LiPo with a PH2.0 connector. This CNHL MiniStar 900mAh pack provides approximately 157% more rated capacity, offering additional energy for compatible crawlers without changing the cell count. Actual runtime depends on the motor, gearing, terrain and driving style.
The CNHL battery is approximately 15g heavier than the common stock pack and has a different case shape. Check the battery holder and weight distribution before fitting it to an SCX24 Bronco, Jeep Gladiator, Toyota 4Runner or other SCX24 variant.
PH2.0 and JST Connectors for Small RC Models
The battery offers PH2.0 and JST connection options for compatible 2S RC electronics. PH2.0 is used on common Axial SCX24 configurations, while JST connections can be found on selected small RC models. Confirm the exact connector type, gender, pin arrangement and polarity before use. Do not connect the same battery to multiple powered models simultaneously.
Battery Option for Furitek Terra COMP 1/18 Crawler
The Furitek Terra COMP 1/18 is another application where a compact 900mAh 2S pack may be worth considering. Compared with an 800mAh reference battery, 900mAh offers 12.5% more nominal capacity. Confirm the actual battery holder, connector and voltage requirements before installation. See the Furitek Terra COMP 1/18 Review.
2S Battery Upgrade for Redcat Ascent 18
The CNHL MiniStar 900mAh 2S may be considered for compatible Redcat Ascent 18 Scout II Brushless and Ascent 18 APEX configurations. Check the vehicle's battery compartment, main connector and polarity before switching packs. Explore the Redcat Ascent 18 Battery Upgrade Guide.
900mAh 2S Battery Option for Redcat SixtyFour-18
The Redcat SixtyFour-18 1/18 hopping lowrider uses a 2S battery system. This CNHL 900mAh pack offers 20% more rated capacity than a 750mAh reference pack, but the 55 × 30 × 12mm dimensions and PH2.0/JST connector arrangement require verification before installation. Compare suitable options in the Redcat SixtyFour-18 LiPo Battery Collection.
Can This 900mAh 2S Battery Power UMX Aircraft?
Some lightweight RC aircraft use 2S batteries with small connectors, but 2S voltage alone does not establish UMX compatibility. For example, the E-flite UMX Eratix 3D FF 450mm recommends a much smaller 300mAh pack, so this 39g 900mAh battery is not an appropriate stock replacement. Check the aircraft's battery recommendation, connector and CG before choosing a pack.
For model-specific details, see the E-flite UMX Eratix 3D FF Guide and our CNHL 900mAh Battery for SCX24 and UMX Models article.

The CNHL pack offers substantially more rated energy but weighs approximately 15g more. The added battery mass can affect suspension behavior, center of gravity and climbing balance. Actual runtime will not necessarily increase in direct proportion to capacity.
2S LiPo Charging and Battery Care
This is a standard 7.4V 2S LiPo battery with a maximum balanced charge voltage of 8.40V (4.20V per cell). It is not a 2S LiHV battery and must not be charged to 8.70V.
For routine charging, a balanced 1C rate of 0.90A per battery is preferred. The specified maximum is 5C, equivalent to 4.50A, but that is not the everyday charging recommendation. Make sure the charging leads, connectors and charger are rated for the chosen current.
Use a compatible 2S LiPo balance charger and the correct JST-XH balance connection. Do not assume the stock USB charger supplied with a different battery can safely charge this larger-capacity pack. Allow the battery to cool before recharging and use a storage-charge program for extended periods of non-use.

FAQ
Is this a good Axial SCX24 battery upgrade?
It is a higher-capacity 2S PH2.0 option for compatible SCX24 models. The 900mAh capacity is approximately 2.57 times the common stock 350mAh battery, but the case dimensions and 39g weight require a physical fit check.
Will it fit an SCX24 Bronco, Gladiator or Toyota 4Runner?
These models use 2S battery systems, and common versions use PH2.0 connections. Confirm the specific vehicle's battery mount, connector polarity, wire routing and space for the 55 × 30 × 12mm battery before use. A guaranteed modification-free fit is not established for every version.
How much longer will 900mAh last than 350mAh?
The 900mAh battery offers approximately 157% more rated capacity than a 350mAh pack. Actual runtime gains depend on motor load, terrain, gearing, vehicle weight and driving conditions; a fixed runtime cannot be guaranteed.
What are the PH2.0 and JST connectors for?
They offer connection options for compatible 2S RC models. Always confirm the exact JST type, connector polarity and appropriate current capacity. Having two connector options does not mean the battery is universally compatible with all SCX24 or UMX models.
Can this battery be used in a Furitek Terra COMP or Redcat Ascent 18?
It may be considered for compatible 2S configurations, but confirm the actual battery holder, connector, polarity and vehicle electronics. Model-specific fit and performance are not guaranteed solely by matching voltage.
Is this suitable for Redcat SixtyFour-18?
Its 900mAh capacity provides 20% more rated capacity than a 750mAh reference battery at the same 2S voltage. Confirm battery-compartment clearance, main connector and polarity before use.
Can I use it in an E-flite UMX Eratix 3D FF?
It is not recommended as a stock replacement. The Eratix 3D FF 450mm specifies a much smaller 2S 300mAh flight battery, so the 39g CNHL pack is significantly heavier than the reference setup.
Is this a standard LiPo or LiHV battery?
It is a standard 7.4V 2S LiPo battery. Maximum balanced charge voltage is 8.40V total, or 4.20V per cell. Do not use a LiHV charging setting.
What charging current should I use?
For routine charging, 1C equals 0.90A per battery. The specified maximum is 5C, equal to 4.50A, but the charger and all charging connections must support the selected current.
How many batteries are included?
Select the desired 2-pack or 4-pack option on the product page. Each individual battery has 900mAh capacity and is normally installed, used and charged separately.
Notice
- This is a standard 2S LiPo battery with a maximum charge voltage of 8.40V (4.20V per cell).
- Use a suitable 2S LiPo balance charger. Do not select LiHV mode.
- Confirm battery dimensions of 55 × 30 × 12mm, approximately 39g weight, connector polarity and secure mounting before ordering.
- Matching the battery voltage and connector does not guarantee physical compatibility.
- SCX24 and other small RC models may require different mounting arrangements due to the larger battery dimensions and weight.
- Confirm the exact PH2.0 or JST connector type and polarity before connecting the battery.
- Do not use both power outputs to operate separate devices simultaneously.
- Check that the power leads and connectors can safely handle the actual load and charging current.
- Never charge unattended. Inspect the pack and cell voltages before charging or use.
- Do not charge or operate swollen, punctured, damaged, overheated or otherwise abnormal batteries.
- Do not attempt to restore a defective battery through repeated charge/discharge cycling.
- Allow the battery to cool before charging and use an appropriate storage program for extended periods of non-use.
- Inspect the battery after crashes, hard impacts or excessive vibration.
