About the Losi Promoto Platform
The Losi Promoto series combines advanced electronic control with mechanical precision, featuring a flywheel-stabilized chassis, chain drive, and adjustable suspension geometry. Both the MX (off-road) and SM (street) versions share the same internal layout and battery tray, ensuring cross-compatibility for all CNHL 2S LiPo packs.
Why Upgrade to CNHL Racing Series Batteries
The stock Spektrum 5000mAh 2S pack is functional but limits throttle punch and runtime. CNHL Racing Series batteries, built with a 120C discharge rating, deliver the continuous current flow needed for full-speed wheelies, hard braking, and precise MS6X control. The hard case design ensures safety and durability even in high-vibration dirt tracks.
Choosing Between 5600mAh, 6000mAh LiHV, and 6600mAh Packs
If you’re seeking pure acceleration, the 5600mAh 120C pack provides the lightest setup with maximum power delivery. The 6000mAh LiHV pack increases voltage and responsiveness, perfect for riders who enjoy dynamic wheelie control. The 6600mAh 120C version offers the longest runtime — ideal for endurance sessions and extended bashing days.
FAQ
- Are these batteries compatible with both Promoto MX and Promoto SM?
Yes. Both models use the same 2S EC5 battery bay, so these CNHL packs fit perfectly in either version. - Can I use a 3S pack?
No. The ESC and motor are designed for 2S only. Using a 3S may damage the electronics. - What’s the difference between LiPo and LiHV?
LiHV batteries offer a slightly higher voltage (7.6V vs 7.4V), delivering a bit more punch and top speed potential. - Which pack gives the longest runtime?
The CNHL 6600mAh 7.4V 120C battery offers the longest ride time among the recommended options.
