Did the wires come loose from one of the cells?

superek4 · 04.19.2009, 09:17 AM

no but 1 cell is dead three other cell is abt 3.8v but the total volt is 7.5v y? i tried to charge but no batt detected, i used a volt meter no volt detected also. i suspect some wires in the lipo is loose.

anyone managed to get a replacement from hobbycity?

I think a few people have been successful who had issues- hobbycity do have good aftersales support apprently- well worth contacting them.

Three months old, it was a 4s 5000 zippy

This is why zippys are cheap and why you should tape the cells together. When you get a pack back, I would recommend taking the shrink off, taping the cells with packaging tape or something similar, then re-shrinking the pack. It will keep the cells from shifting and the solder joints from coming undone.

I am running 2 3s 5000 and the frist thing i did when i got them was cut the pack opan and resolder all the conections, than re wrap the pack like metallover said. Since than i have never had a problem with the lipos. I look at it like another 15 minutes verses the money i am saying, it is well worth it
