hard pack salvage?????????

[stelerzman]

Hey guys I could use some info on salvaging some Turnigy 5000 mah 2 cell hard case batteries. I have 6 of them that haven't been used or charged in quite some time and the voltage reads between 7.52 &8.180 volts. My main concern is the hard case has expanded to 1 1/8" which is larger than the 13/16" the case was originally. Are these batteries safe to use?????. I want to run them in the Supirior Ul-1. It will be the first time I have attempted to power up the boat.

Thank you for any info you can offer.

I'd shy away from them, especially in a power greedy application like a boat. That puffing will only get worse.

Use em' till they burn baby burn! I had a few 3000mah Turnigys that were puffed like a balloon and they lasted me another 33 months. Just use a lipo sack when you charge them and charge them on some tile or concrete surface!

In my experience you will loose about 30%in run time and in punch power also they will be out of balance but safe to use. that's from 10 years of compative electric on-road racing

I'm a racer, too. I've seen plenty of battery fires, property damage and cooked cars in the past year. Is it worth risking an RC vehicle, or your home, for the sake of saving a few bucks?

lipos are so cheap why take the chance

Thank you all for your input. I've decided to order new batteries, but in the mean time I'll use the ones I have and be very cautious on the throttle. I'm hoping to launch the boat tomorrow for a little test run. I have the throttle epa set to 75%. I hope I receive the batteries soon because I want to see the ul-1 fly across the water.
