This is a battery bracket upgrade I did for my Turnigy TZ4 1/28 Scale RC Car. I replaced the stock 400mah battery with a 800mah battery and it was putting too much stress on the elastic band that held it in place, it was not very protected because of how much taller it is..
The mod is derived from replacement PN 9315000194-0
