Hobbywing EZRun MAX8 G2 ESC Features:
- The ESC uses a special process, coupled with an innovative waterproof design, to increase waterproofing and dust-proofing performance in different climates. It is easy to deal with the harsh conditions containing sediment, ice, and snow, water accumulation.
- Built-in ultra-powerful switch mode BEC with a continuous current of 6A, an instant 15A, and support for 6V/7.4V/8.4V switching, supporting a wide range of powerful and high-voltage servos.
- Equipped with the most advanced and safe electronic switches. The traditional mechanical switch protects and prevent dust, humid and other harsh environments, contact rust, and violent impact (such as flying slope landing) caused by the automatic closure of mechanical switches and other issues.
- Support the 32 degree turbo timing setting. When used with the matching motor (such as EZRUN 4278SD), the maximum rpm can be increased by about 25%, easily win your rival. • Multiple protection functions: battery low voltage protection, ESC and motor overheat protection, signal loss protection, current protection.
- Support LED program card, LCD G2 program box, OTA programmer (Note: optional) to set the parameters of the ESC.
- Real-time data logging to view various running data on the HW LINK app using the OTA Bluetooth module.
- Support the firmware upgrade of the ESC (The multi-function LCD G2 program box or OTA Programmer is needed to purchase), you can enjoy the latest functions.

Questions & Answers
The 2250kv system will run 4s or 6s depending on the application. It has XT90 plugs on it.
No, this is for a 1/8th scale car. you can look at something like this for the Zorro HW38020344
I am sorry we do not know that vehicle but this is a very good 1/8 brushless system and we recommend 2x 3s lipos like this SCH-CR780
It will run with either but you would need a loop connector to run one battery if it has 2 connectors.
Yes this would work in that car for you.
Yes this one HW38010404
No, this is only available with the XT90 connectors
The g2 is the latest version :)
No this is pre soldered with xt90 connectors on it.
