The video review (Spanish)
After testing other HobbyKing packs, I used the 6500mAh Turnigy Rapid 4S in the MJX 7303. HobbyKing supplied it through the channel partnership, a relationship reflected in the video and links.
The Tested Pack
It is a 4S hardcase pack with XT90. The label advertises 140C discharge, a commercial rating I do not certify through a current test here.
Before use I checked all four cells, finding them around storage voltage with small differences. This is reception inspection of one pack, not the entire series.
How It Worked in the 7303
It let me enjoy the car with the delivery expected from that 4S configuration. A timed session appears, but not repeated-condition runtime testing or an equivalent pack comparison.
I recorded no under-load voltage curve, so good impressions are not measurements of electrical stability or internal resistance.
Car and Battery Are Separate Tests
I hit the car and lost parts during use. That belongs to the session and my driving; it proves neither a battery defect nor that this battery makes the car tougher.
The MJX 7303 review covers the vehicle. This entry concerns the pack, format and user experience.
My Takeaway
I was happy with it in my car. Before choosing one, check dimensions, connector, permissible voltage and the exact reference’s charging conditions.
Price, shipping and the TOPERC code discussed were conditions at recording, not promises of current terms. Check them when ordering.
