Why choose the Overlander 3261EC5?
Combining a 4000mAh capacity with a 50C continuous discharge rate (200A), this low-profile pack ensures consistent power delivery, lower heat build-up, and excellent runtime—perfect for both RC racers and off-road hobbyists. The reinforced hard case protects against impacts and track debris, while the EC5 connector provides high-current compatibility for demanding setups.
Key features
- 4000mAh 3S (11.1V) LiPo battery in low-profile hard case
- EC5 connector for efficient, high-current transfer
- 50C continuous discharge rate with higher burst output
- 10 AWG silicone leads with JST-XH balance plug
Performance & output
Delivering a strong 200A continuous discharge capability, the 3261EC5 is ideal for brushless systems where acceleration and sustained top speeds matter. The 44.4Wh energy output balances endurance with lightweight construction, providing excellent runtime for competitive racing conditions.
Low-profile advantage
With its reduced height, this pack is designed to fit into tight battery compartments and offers improved handling by lowering the vehicle’s centre of gravity. This is especially useful for touring cars, drift setups, and buggies where balance and agility are critical.
Hard case durability
The ABS hard case adds protection against damage from vibrations, collisions, and rough terrain. This ensures the cells remain secure and reliable through intense racing or extended bashing sessions.
EC5 connector compatibility
The EC5 connector ensures maximum efficiency in high-current applications, reducing resistance and preventing voltage drop under load. This makes the 3261EC5 a reliable option for heavy-duty brushless motor systems and high-demand ESCs.
BRCA-approved assurance
As part of Overlander’s Sport Track series, the 3261EC5 is BRCA-approved, meaning it’s race-legal and trusted by competitive RC drivers across the UK.
Fullymax precision cells
Each Overlander pack uses Fullymax precision-matched cells, ensuring consistency across voltage, resistance, and weight. This matching delivers smoother discharges, improved performance, and extended lifespan compared to generic LiPo packs.
Best use scenarios
- RC cars—touring, drifting, and buggies needing slim battery options
- Off-road racing where improved stability from lower centre of gravity is vital
- Brushless motor builds requiring high continuous current delivery
- Competition tracks where BRCA approval is required
Care & maintenance tips
- Charge only with a balance charger designed for LiPos
- Store at 3.8V per cell when not in use for extended periods
- Securely fit into battery trays to avoid movement during runs
- Inspect casing regularly for swelling or damage
Customer impressions
Users praise the 3261EC5 for its excellent fit in low-clearance chassis, reliable output, and strong runtime. Many racers report better balance and handling with the reduced height, while hobbyists appreciate its hard case protection and consistency under load.

We want to make sure your delivery goes smoothly, so here are some important details about our service:
- For orders above £120, we offer delivery to most mainland UK addresses. For orders under £120, we can still deliver to Northern Ireland and the outlying isles, as long as the item can be sent by Royal Mail, weighs less than 30kg, and fits within 61cm × 46cm × 46cm.
