The Dynamite P-DYNM3876 120A Marine ESC for 2–6S LiPo brushless RC boats is a high-performance, water-cooled controller engineered for medium to large hulls demanding precision, power, and durability. Designed for platforms like the Blackjack 29 V3, deep-V hulls, catamarans, and airboats, this ESC delivers 120A continuous current and up to 720A burst capacity, making it ideal for aggressive throttle profiles and extended high-speed runs. With full forward/reverse/brake functionality, programmable cutoff, and marine-specific firmware, the Dynamite P-DYNM3876 offers refined control and thermal stability in demanding aquatic environments.
Key features of the Dynamite P-DYNM3876 120A Marine ESC
- 120A continuous current – supports high-output brushless motors for serious marine propulsion
- Waterproof and water-cooled housing – marine-grade enclosure with integrated cooling jacket for thermal management
- Reverse-enabled drive – enhances maneuverability for docking, recovery, and tight water turns
- Programmable brake – includes time-delay functionality for smoother deceleration and safer transitions
- 6V switching BEC – powers receiver and servos with stable voltage delivery
- IC5 connector – ensures secure, high-current connectivity with LiPo battery packs
How does the Dynamite P-DYNM3876 handle high-current marine loads?
The Dynamite P-DYNM3876 marine ESC with 720A burst current, 6V switching BEC, and 5.5mm bullets is built to withstand the demands of high-speed aquatic platforms. Its 120A continuous rating ensures consistent power delivery during sustained throttle runs, while the 720A burst capacity provides headroom for acceleration spikes and peak loads. The integrated water-cooled housing actively dissipates heat, allowing the ESC to operate efficiently under prolonged stress without thermal shutdown.
Why is reverse functionality important in RC boats?
The Dynamite P-DYNM3876 waterproof ESC with IC5 connector, reverse, and programmable brake includes full directional control for enhanced maneuverability. Whether you're repositioning after a missed turn, navigating docks, or recovering from obstacles, the reverse function adds flexibility that forward-only ESCs cannot offer. Combined with programmable brake settings and time-delay deceleration, this ESC provides a smoother and safer driving experience across varied water conditions.
What battery configurations does the Dynamite P-DYNM3876 support?
The 2–6S brushless marine ESC with time-delay brake, overload protection, and programmable cutoff supports both 2–6S LiPo and 6–18 cell NiMH setups, offering broad compatibility for speed tuning and runtime optimization. Users can tailor their power systems to match hull type, motor KV, and water conditions. The programmable low-voltage cutoff protects batteries from over-discharge, while the overload protection safeguards internal components during current surges or motor stalls.
How does the ESC maintain efficiency under load?
The Dynamite P-DYNM3876 with 120A continuous current, 12 AWG input leads, and .0005 ohm resistance is optimized for low-resistance power transfer and high-current throughput. The 12 AWG input leads support high-discharge rates, while the internal resistance of just .0005 ohms minimizes energy loss and heat buildup. These specifications ensure that the ESC delivers clean, efficient power to the motor, even during full-throttle operation or rapid directional changes.
Which RC boats are best suited for this ESC?
The RC boat ESC for Blackjack 29 V3, deep-V hulls, catamarans, and airboats with water-cooled housing is designed for medium to large-scale platforms that operate in open water or competitive racing environments. Its compact footprint fits most standard marine ESC trays, and its sensorless design simplifies installation and reduces failure points. Whether you're building a custom speed boat or upgrading a stock system, the Dynamite P-DYNM3876 offers plug-and-play compatibility with high-performance marine setups.

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. Some highland and remote areas may carry an extra delivery charge as couriers often apply surcharges in these locations. If you live in one of these areas, feel free to contact us before ordering so we can confirm the delivery options and costs for you.
- Most of our products include delivery in the price. If your order is under £90, a small delivery fee will apply but do not worry this will always be clearly shown at checkout before you complete your purchase.
- Depending on what you choose at checkout, your order will usually be delivered either the next working day or within 2 working days. For next day delivery please place your order before 2:00pm. Orders are dispatched Monday to Friday only. Some items may take a little longer and if that is the case we will always show the expected delivery time on the product page.
- If your order includes items with different dispatch times we will normally wait and send everything together once all items are in stock. If one of the items is going to take a while we will give you the choice either wait for everything to arrive or let us send the available items now and deliver the rest later. It is up to you.
- We use trusted delivery partners to make sure your order gets to you safely and on time. We use DPD for next working day deliveries and Royal Mail for the 2 day option.
- As soon as your order is on its way we will send you a tracking number by email. If you provide your mobile number at checkout we will also send delivery updates straight to your phone so you can keep an eye on progress.
- If a product is marked as "Dispatched within 3 working days" delivery usually takes around 3 to 5 working days from when your order is placed.
- For customers in Inverness and other parts of the Scottish Highlands deliveries can take up to 2 working days even if you select next day delivery as couriers do not currently offer a guaranteed next day service to those areas.
