What Is a 1S Shorty LiPo Battery?
A 1S Shorty LiPo battery is a single-cell RC racing battery installed inside a wide, low-profile hardcase. This battery format is most closely associated with lightweight on-road racing platforms that are designed specifically around 1S power.
Depending on the manufacturer and racing community, the same general battery category may also be described as a:
- 1S shorty battery;
- 1S stick LiPo battery;
- 1S hardcase LiPo battery;
- 1S pan car battery;
- 1S LCG battery;
- 1/12 scale racing battery;
- GT12 LiPo battery;
- LMP12 battery.
These terms can describe similar products, but exact dimensions, terminal positions, weight, chemistry and competition approval differ between individual battery models. Always check the complete specification rather than relying on the category name alone.
1S Shorty LiPo Batteries for 1/12 Pan Cars
The primary application for this battery class is the 1/12 pan car, including LMP12-style prototype racers and closely related competition chassis. These cars use a lightweight, low-profile platform where battery size and installed mass directly influence chassis balance and center of gravity.
A typical 1S racing hardcase is approximately 91–93mm long, 46–47mm wide and 18–19mm high. This wide and flat shape allows the battery to sit low inside a compatible chassis while still providing the capacity required for complete race runs and extended practice sessions.
Drivers searching for a 1/12 pan car battery should compare:
- case length, width and height;
- battery weight;
- terminal diameter and position;
- capacity and discharge capability;
- LiPo or LiHV chemistry;
- maximum permitted race voltage;
- competition approval requirements.

The 8200mAh capacity provides substantial energy reserve for complete race runs, repeated setup changes and longer track sessions. Actual runtime and voltage behavior depend on the motor, gearing, ESC settings, boost or turbo timing, track layout, tyre load, vehicle weight and driving style.
GT12 LiPo Batteries
GT12 cars commonly use a low-profile 1S battery format similar to the packs used in 1/12 pan cars. The single-cell system helps maintain a lightweight platform while the wide hardcase battery can contribute useful mass low in the chassis.
When choosing a GT12 LiPo battery, check more than the voltage. Different chassis may use different battery retention systems, terminal orientations and weight distributions. The battery must fit securely without interfering with the body shell, wiring, rear pod or side-link movement.
Competition requirements also vary. Some GT12 clubs allow any commercially available hardcase battery that meets their dimensional and voltage limits. Other events require the exact model to appear on an approved or homologated battery list.
LMP12 Batteries for Prototype Pan Cars
LMP12 generally refers to 1/12-scale prototype-style pan cars with low aerodynamic bodies and direct-drive rear pods. These cars are highly sensitive to total weight, left-to-right balance and battery placement.
A suitable LMP12 battery should provide:
- the correct 1S voltage;
- a low-profile case that fits the chassis restraint system;
- sufficient capacity for the intended race duration;
- adequate current delivery for the selected motor and ESC;
- predictable weight for chassis setup;
- the required approval status for the intended event.
The CNHL 8200mAh 1S Shorty LiHV pack is positioned as a high-capacity and cost-conscious option for compatible LMP12 platforms used in practice, testing, club racing and events that allow the specific battery.
1S Shorty LiPo vs 2S Shorty LiPo
A 1S shorty battery and a 2S shorty battery may both use compact hardcases, but they are not interchangeable. The cell count changes the voltage supplied to the complete vehicle.
| Feature | 1S Shorty LiPo | 2S Shorty LiPo |
| Nominal Voltage | 3.7V LiPo or 3.8V LiHV | 7.4V LiPo or 7.6V LiHV |
| Primary Vehicles | 1/12 pan car, LMP12 and GT12 | 1/10 drift, touring, buggy and other 2S cars |
| Required ESC | Purpose-built or verified 1S-compatible ESC | 2S-compatible ESC |
| Receiver Power | May require a boost BEC or voltage booster | Normally supplied by a standard ESC BEC |
| Typical Case Height | Often approximately 18–19mm | Often substantially taller |
Do not purchase a 1S battery as a replacement for a standard 2S shorty solely because the length and width appear similar.

1S Shorty RC Car Battery vs Micro 1S Drone Battery
The phrase “1S LiPo battery” is also widely used for Tiny Whoop drones, micro helicopters and small RC aircraft. Those products are completely different from the high-capacity hardcase packs used in 1/12 RC cars.
| Comparison | 1S Shorty RC Car Battery | Micro 1S FPV Battery |
| Construction | Wide hardcase racing battery | Small exposed softcase battery |
| Typical Capacity | Several thousand mAh | Usually a few hundred mAh |
| Primary Application | 1/12 RC car racing | Tiny Whoop, micro FPV and small aircraft |
| Typical Connector | 4mm or 5mm bullet terminals | PH2.0, BT2.0, A30 or similar micro connector |
For FPV drones and other lightweight models, browse the CNHL 1S LiPo battery collection.
How to Choose a 1S Pan Car Battery
Measure the battery compartment
Measure the maximum usable length, width and height inside the chassis. Allow additional clearance for bullet plugs, ESC leads, capacitors, battery retainers and the body shell.
The battery should not move during acceleration, braking or cornering, but it should also not be forced into the chassis under excessive pressure.
Check the battery weight
Battery weight affects total vehicle mass and side-to-side balance. A lighter battery may require ballast, while a heavier battery can reduce the freedom to position weight elsewhere on the chassis.
Compare the battery weight with the chassis manufacturer’s recommended setup and the minimum weight required by the racing class.
Verify the terminal size and polarity
Many 1S racing batteries use 4mm or 5mm bullet terminals instead of permanently attached discharge wires. Check the plug diameter, polarity, insertion depth and terminal location before connecting the ESC.
Never allow the exposed positive and negative terminals to contact each other.
Confirm the complete 1S electronics system
The ESC and motor must support 1S operation. The receiver, steering servo, transponder and cooling equipment must also receive a stable supply voltage.
A vehicle being physically large enough for the battery does not prove that its electronics can operate correctly from one cell.
Why a 1S Racing Car May Need a Voltage Booster
A conventional ESC BEC normally reduces the main battery voltage to power the receiver and steering servo. With only one battery cell, an ordinary step-down BEC may not have enough input voltage to produce a stable receiver output.
A complete 1S racing setup may therefore use:
- a purpose-built 1S ESC with an integrated boost BEC;
- an external DC-DC voltage booster;
- a separate receiver battery where the rules and chassis allow it;
- another receiver power solution specified by the electronics manufacturer.
Check the required voltage and current for the receiver, servo, transponder, cooling fan and any other installed equipment. An unstable receiver supply can cause weak steering, radio resets or loss of control.
1S LiPo vs 1S LiHV Batteries
A standard 1S LiPo battery normally has a nominal voltage of 3.7V and a maximum charge voltage of 4.20V. A 1S LiHV battery normally has a nominal voltage of 3.8V and may support charging to 4.35V when permitted by the battery manufacturer.
| Battery Type | Nominal Voltage | Typical Maximum Charge Voltage |
| 1S LiPo | 3.7V | 4.20V |
| 1S LiHV | 3.8V | Up to 4.35V when permitted |
Many racing organizations set their own maximum charging or inspection voltage. A LiHV battery may be charged to 4.20V when required, although this does not use the pack’s complete high-voltage capacity.
Always follow the lowest applicable limit established by the battery manufacturer, charger instructions and event regulations.
High-Capacity 1S Batteries for Practice and Racing
High-capacity 1S batteries are commonly selected to provide sufficient energy for full race runs and repeated practice sessions. Capacity can also help reduce the rate at which the pack voltage declines during a demanding run, although actual performance depends on more than the printed milliamp-hour figure.
When comparing 1S racing batteries, consider:
- voltage retention during the complete run;
- internal resistance;
- battery temperature;
- weight and chassis balance;
- consistency between charge cycles;
- connector resistance;
- cell age and storage history.
A high printed C-rating should not be used as the only basis for comparing products from different manufacturers.
Compatible 1S Shorty Battery Applications
| Application | Suitability | What to Check |
| 1/12 Pan Car / LMP12 | Primary application | Battery tray, installed weight, terminals and 1S electronics |
| GT12 | Recommended with checks | Chassis dimensions and event battery requirements |
| Open-rule Club Racing | Good application | Confirm that non-homologated commercial hardcase packs are permitted |
| Practice and Setup Testing | Good application | Match battery weight and voltage to the intended race setup |
| 1S World GT or Oval | Possible | Verify the exact chassis, class voltage and battery dimensions |
| Custom 1S Buggy | Specialist use only | Do not assume compatibility based on battery length alone |
| Standard 1/10 Drift Car | Usually unsuitable | Most conventional drift systems require a 2S battery |
| Standard Touring Car or Buggy | Not a direct replacement | Use only when the complete vehicle is specifically configured for 1S |
Practice, Club Racing and Sanctioned Events
A high-capacity 1S shorty battery can be suitable for regular club nights, practice, driver training, tyre testing, gearing comparisons, ESC setup work and chassis-balance adjustments.
However, a battery that fits the chassis is not automatically approved for every race. Competition eligibility may depend on:
- the exact manufacturer and model number;
- the current approved battery list;
- case dimensions and construction;
- maximum pre-race voltage;
- connector and wiring requirements;
- club-specific rules.
Unless an individual product page explicitly states otherwise and the exact model appears on the applicable current list, do not assume that a battery is ROAR approved, IFMAR approved, EFRA homologated, BRCA approved or legal for every sanctioned competition.
Drivers should check the latest rules directly with the event organizer before purchasing a battery specifically for regulated racing.

Frequently Asked Questions
What RC cars use a 1S Shorty LiPo battery?
Purpose-built 1/12 pan cars, LMP12 racers and many GT12 cars are the primary applications. Selected World GT, oval and custom racing platforms may also use this battery format. Always confirm the required voltage and physical dimensions for the exact chassis.
Is a 1S Shorty LiPo the same size as a 2S Shorty battery?
Not necessarily. The length and width can be similar, but 1S racing batteries are often lower in height. More importantly, a 1S battery provides approximately half the voltage of a 2S pack and is not a direct electrical replacement.
Can I use a 1S Shorty battery in an RC drift car?
Only when the complete drift system is specifically designed for 1S operation. Most conventional 1/10 drift cars use a 2S battery, so a 1S pack may provide insufficient motor speed and may not support the ESC BEC, steering servo, receiver and gyro correctly.
Do 1S pan cars require a voltage booster?
Many do. Some specialist 1S ESCs include an integrated boost BEC, while other systems require an external DC-DC booster or another receiver power solution. Check the ESC specifications and the voltage requirements of the servo and receiver.
Is every 1S Shorty battery legal for GT12 or pan car racing?
No. Correct voltage and physical fit do not guarantee competition eligibility. Some events require the exact battery model to appear on an approved or homologated list. Check the current organizer rules before purchasing for a regulated race.
Can a 1S LiHV battery be charged to 4.35V?
A LiHV battery may support charging to 4.35V per cell when permitted by the manufacturer and charged with a compatible LiHV charger. Many racing rules impose a lower maximum voltage, frequently 4.20V, so follow the limit applicable to your event.
What connector does a 1S Shorty racing battery use?
Many high-capacity 1S hardcase batteries use direct 4mm or 5mm bullet terminals. Terminal diameter, polarity and position vary, so confirm the product specification and ESC wiring arrangement before connecting the battery.
