Quick Fit Check
The [Combo] 2 Packs CNHL MiniStar 850mAh 14.8V 4S 70C LiPo Battery with XT60 Plug is a compact high-voltage battery set for pilots and drivers who need strong 4S punch in a small, lightweight pack. With two matching 850mAh 4S batteries, 14.8V voltage, 70C discharge output, XT60 connectors, and an approximately 110g weight per pack, this combo is well suited for 100–180mm FPV drones, small RC airplanes, compact racing builds, and selected small-tray crawler setups where 4S power is supported.
This battery set is best used when your model supports 14.8V 4S LiPo power, has enough space for a 62 × 30 × 33mm pack, and uses an XT60 connector or a properly rated adapter. For FPV drones, check motor KV, ESC rating, prop size, all-up weight, and battery strap position. For crawlers such as Redcat Vertex 10 and Vertex 10W, confirm ESC settings, battery retention, wire routing, and whether 4S power is appropriate for your driving style.

Core Description
The CNHL MiniStar 850mAh 4S 70C LiPo battery is built for compact RC setups that need higher voltage without carrying a large battery. Compared with a similar 3S pack, this 4S version gives stronger voltage, sharper throttle response, and more punch, while still keeping the battery small enough for compact FPV and lightweight RC platforms.
The 850mAh capacity keeps weight under control, which is important for 100–180mm FPV drones, small RC airplanes, and tight battery-tray builds. The 70C discharge rating gives this pack the current support needed for short, responsive flights and higher-load throttle changes.
This listing includes two matching MiniStar 850mAh 4S packs, making it useful for back-to-back flying, tuning, practice sessions, or keeping one pack ready while the other cools after use. For most models, these packs are used one at a time unless the model is specifically designed for multi-pack wiring.
4S LiPo Battery for 100–180mm FPV Drones and Small RC Aircraft
The CNHL MiniStar 850mAh 14.8V 4S 70C LiPo Battery with XT60 Plug is designed for compact RC helicopter, airplane, quadcopter, drone racing, and FPV hobby setups where 4S voltage and XT60 wiring are required. It can be considered for 100mm to 180mm FPV multirotors, small RC airplanes, and similar compact 4S platforms.
Typical use cases include small multirotor FPV builds, micro racing drones, compact freestyle setups, and small RC aircraft such as the Durafly PNF MFX Racer when voltage, battery bay size, connector, CG, and ESC rating match.
For compact FPV use, 4S battery selection should be checked carefully. A pack that is too heavy can make the aircraft sluggish, while a pack that is too small may sag quickly under load. This 850mAh 4S pack is aimed at pilots who want a compact, punchy power source for short high-output flights.
XT60 Version and XT30 Alternative
This battery comes with an XT60 plug, which is useful for models already wired around XT60 connectors. XT60 can be a cleaner choice when your ESC and power lead are already set up for that connector format, especially when current demand is higher than very small micro connectors are designed to handle.
We also offer the same 850mAh 4S battery with an XT30 plug for models that use smaller connector hardware: 4S 850mAh with XT30.
Also Recommended for Redcat Vertex 10W Power Setups
The [Combo] 2 Packs CNHL MiniStar 850mAh 14.8V 4S 70C LiPo Battery with XT60 Plug is a compact 4S option selected for experienced drivers who want extra brushless punch from the Redcat Vertex-10 and Redcat Vertex 10W crawler platform. Both RTR models are 2S–4S LiPo ready and use an XT60 connector, making this MiniStar 4S pack a compact higher-voltage option when fitment matters.
Compared with 3S, 4S gives the Vertex 10 platform a sharper and more aggressive throttle feel. It can be useful for experienced drivers running the wider Redcat Vertex 10W on open rock gardens, steep climbs, and lines where extra wheel speed can help. For general crawling, technical throttle control, and longer trail sessions, many drivers may still prefer 3S or a larger-capacity 3S pack.
This 850mAh 4S pack is best understood as a compact punch / test / short-session battery rather than a maximum-runtime crawler pack. It can help with lightweight setup testing and fitment-sensitive builds, but runtime will be shorter than larger 1500mAh, 2200mAh, or 3000mAh crawler batteries.

Why Choose a 2-Pack 850mAh 4S MiniStar Set?
A two-pack 850mAh 4S battery set is practical for RC pilots because compact models often have short, high-output flight windows. With two identical packs, you can complete more test flights, tune throttle curves, compare prop setups, or fly back-to-back without switching to a different battery size.
For small FPV and aircraft use, matching capacity and weight from flight to flight helps keep the model feel consistent. For crawler users testing 4S on a Vertex 10 or Vertex 10W platform, two matching packs also make it easier to compare ESC settings, throttle response, and battery placement.
Applications
- 100mm to 180mm FPV multirotors using 4S LiPo power

FAQ
What is this 2-pack 850mAh 4S LiPo set best used for?
It is best used for 100–180mm FPV drones, micro racing builds, small RC airplanes, compact 4S aircraft, and Redcat Vertex 10 / Vertex 10W short-session 4S setups.
Can this battery work in FPV racing drones?
Yes, it can work in compact 4S FPV racing drones when the frame, motors, ESC, prop setup, connector, and battery strap position are suitable.
Can this battery work in the Redcat Vertex 10W?
Yes, it can be used as a compact 4S option for Redcat Vertex 10W setups where tray fitment, wire routing, ESC settings, and driver experience are suitable. It is best for punch, testing, and short technical sessions rather than maximum runtime.
Should Redcat Vertex 10 drivers choose 3S or 4S?
For most everyday crawling, 3S is the easier and more controlled choice. 4S gives sharper wheel speed and stronger punch, but it is better suited to experienced drivers and open lines where extra power is useful.
Why choose the 2-pack version?
The two-pack version gives you more repeat sessions with the same battery size and weight. This is useful for FPV tuning, small aircraft flying, and testing 4S behavior in compact crawler setups.
Is XT60 the same as XT30?
No. XT60 and XT30 are different connector formats. This product uses XT60, but a separate XT30 version is available for models that use XT30 connectors.
Can I use both batteries together?
Only use both batteries together if your model and wiring system are specifically designed for multi-pack use. For most compact FPV, small aircraft, and crawler setups, these batteries are used one at a time.
Notice
- Only use a compatible LiPo balance charger designed for 4S LiPo batteries.
- Stop charging immediately if any cell exceeds 4.2V.
- Check voltage, connector type, battery bay size, strap position, wire clearance, ESC rating, and center of gravity before purchase.
- Inspect each battery surface, connector, wires, balance lead, and cell voltage before first use.
- Do not use either battery if it becomes swollen, damaged, overheated, or physically deformed.
- For FPV use, monitor voltage sag and land before over-discharging the battery.
- For crawler use, 4S power should be used carefully, especially in technical lines or tight terrain.
- For long-term storage, store each battery at proper storage voltage in a cool and dry place.
- If a new battery does not initially hold full performance, several normal balanced charge and discharge cycles may help stabilize the cells.
- Always follow standard LiPo safety procedures during charging, storage, transport, and use.
