Low power / voltage

had my alti turn off on the way to altitude 3 times yesterday. after turning back on when on the ground it turns off after a few seconds saying low power even tho its still over 60% battery. After a few attempts it stays on but then again turned off on the way up. only worked on 4 of 7 jumps…

Does it need a battery replacement?

Almost done with it, great alti when it actually works but its not reliable enough. Also onto my 5th bumper case and that has split too, now seems there is nowhere to buy new ones from either
