Quick Fit Check
The 2 Packs CNHL MiniStar 650mAh 7.4V 2S 70C LiPo Battery with XT30U set includes two compact standard-voltage 2S batteries for micro FPV aircraft, small RC vehicles and other lightweight models that use a 650mAh-class 2S power system.
Each battery measures approximately 58 × 30 × 15mm (L × W × H) and weighs approximately 49g. The 650mAh capacity provides more energy reserve than very small 450–550mAh packs while keeping battery size and mass appropriate for many compact RC platforms.
This product contains two separate 650mAh 2S batteries. It is not a single 1300mAh battery, and using two packs individually does not change the voltage or capacity of either battery.

Two Separate 650mAh 2S Batteries
This product contains two individual CNHL MiniStar 650mAh 2S batteries, giving users a convenient second charged pack for back-to-back driving or flying sessions.
Each battery remains a 650mAh 7.4V 2S pack. The two-pack package should not be interpreted as one 1300mAh battery or a 4S battery.
For compact RC vehicles and micro aircraft, a two-pack set is useful because it extends total session time without increasing the weight carried by the model during each run.
Why Choose This 2-Pack?
-
650mAh capacity: More energy reserve than smaller 450–550mAh micro batteries.
-
Approx. 49g per pack: Keeps each individual battery relatively light for compact RC models.
-
58mm length: Compact battery body for tight chassis and aircraft installations.
-
70C continuous output: Suitable for responsive 2S brushless power systems.
-
XT30U connector: Compact connector used by many small RC platforms.
-
Two-pack value: One pack can be in the model while the second is ready for the next run.
-
Standard LiPo chemistry: Charges to 8.40V and does not require LiHV mode.
A Lightweight 2S Battery Option for the Hobby Plus DKR4 Fortis
The CNHL MiniStar 650mAh 7.4V 2S 70C is a compact battery option to consider for the Hobby Plus DKR4 Fortis Brushless.
Its 7.4V 2S configuration follows the truck's 2S power direction, while the XT30U connector and compact battery dimensions make it particularly relevant to small-scale RC platforms where battery space is limited.
At approximately 49g per battery, the 650mAh MiniStar also keeps battery mass conservative. That is useful in the Fortis because its rally-truck body and chassis geometry already place considerable mass above the axles.
A lighter battery will not eliminate the Fortis's naturally higher center of gravity, but it avoids adding unnecessary battery mass high in the chassis and helps preserve responsive acceleration and direction changes on dirt, gravel and trail surfaces.
The 650mAh capacity also gives drivers additional energy reserve over smaller 450–550mAh packs while remaining compact enough to make sense in a 1/18-scale platform.
Because small RC trucks can vary in battery tray dimensions and connector layout, confirm the actual battery compartment, XT30U polarity, wire clearance and retention system before use.
Compare more suitable 2S options in the Hobby Plus DKR4 Fortis Battery Collection.
2S Battery Option for the HPI Venture18 U4 Ford Bronco
The compact 650mAh format is also relevant to compatible HPI Venture18 U4 Ford Bronco setups where a standard 2S battery and XT30U connection suit the vehicle.
For a small-scale crawler or trail truck, battery choice affects more than runtime. Additional battery weight changes climbing balance, side-hill behavior and overall chassis response, so a compact battery can be preferable to simply installing the largest pack that fits.
The 650mAh capacity offers a useful middle ground between very small lightweight packs and higher-capacity batteries that may add unnecessary weight to a 1/18-scale chassis.
See the HPI Venture18 U4 Ford Bronco Battery Guide for more battery-selection information.
Micro FPV and Small 2S Brushless Applications
The combination of 650mAh capacity, approximately 49g weight and XT30U connection also makes this battery relevant to compatible micro FPV aircraft and custom 2S brushless builds.
Compared with a 450mAh pack, 650mAh provides approximately 44% more rated capacity. That can provide additional usable energy, but it also brings more battery mass, so the correct choice depends on the aircraft's frame size and intended flying style.
For lightweight FPV models, smaller packs generally favor agility and lower takeoff weight, while 650mAh can be attractive when cruising time and energy reserve matter more.
Older FPV platforms such as Vortex, FLIP, Tweaker and other small frames have appeared in many different electronics and connector configurations. Treat this battery as a candidate only when the specific build supports standard 2S voltage, accepts the battery dimensions and uses a compatible XT30U connection.

The better battery depends on the model. A 450mAh pack is preferable when minimum mass is the priority, while the 650mAh battery carries substantially more energy and is better suited to platforms that can use the extra capacity without compromising fit or handling.
XT30U Connector
This battery uses an XT30U output connector. XT30U belongs to the XT30 connector family and carries the main positive and negative power connection.
Always confirm connector gender, polarity and physical fit before use.
Models using PH2.0, BT2.0, XT60, EC2, IC2, EC3, IC3 or another connector system require a suitable adapter or professional connector conversion.
Standard 2S LiPo Charging
This is a standard 2S LiPo battery. Maximum balanced charge voltage is 4.20V per cell, or 8.40V total.
Do not charge this battery using a 4.35V-per-cell LiHV mode.
For routine charging, a balanced 1C rate is preferred. 5C is the stated maximum, not the everyday target.
FAQ
Does this product contain one or two batteries?
It contains two separate CNHL MiniStar 650mAh 7.4V 2S batteries.
Do two 650mAh batteries mean this is a 1300mAh battery?
No. Each battery is independently rated at 650mAh. As supplied and used individually, the package does not become a single 1300mAh battery.
Is this a standard LiPo or LiHV battery?
This is a standard 2S LiPo battery with 7.4V nominal voltage and a maximum fully charged voltage of 8.40V.
Is this battery suitable for the Hobby Plus DKR4 Fortis?
It is a compact 2S option to consider for the DKR4 Fortis Brushless when the battery tray accepts its 58 × 30 × 15mm dimensions and the vehicle uses a compatible XT30U connection.
Why choose 650mAh instead of 450mAh?
The 650mAh battery provides approximately 44% more rated capacity, while the 450mAh battery is lighter. Choose based on whether energy reserve or minimum installed weight matters more to the model.
Can this battery be charged to 8.70V?
No. This is a standard LiPo battery, not LiHV. Maximum balanced charge voltage is 8.40V total, or 4.20V per cell.
Is XT30U compatible with XT30?
XT30U belongs to the XT30 connector family and uses the same main positive and negative power-interface direction. Always verify connector gender, polarity and physical fit before connecting the battery.
Should this battery always be charged at 5C?
No. For routine charging, a balanced 1C rate is preferred. The 5C specification is the stated maximum charge rate, not the everyday target.
