A battery plate, which fits nicely into the honeycomb pattern in the chassis of the MJX Hyper Go RC cars (tested in a MJX mjx hyper go 16210 brushless). I use velcro cable ties, which are fed through the middle of the plate.

Both the original MJX 2S Lipo and Ovonic Air 2200mah 2S and 3S Lipos can be secured. The original battery can also be tied down with the connector facing backwards to prevent the connector from slipping out in a crash.

Needs to be printed with supports..
