Voicon Posted January 7, 2021 Share Posted January 7, 2021 Hi All I have 4 x Lipo batteries of varying types that when I put all my rc stuff away I didn't do a storage charge. 3 of the batteries are hard case and 1 soft, the soft case battery has very slight ballooning. All 4 batteries were discharged by use on a car. They've been sat there for at least 3-4 years. I've already thrown 8 batteries, 3 hard case that errored when charging and 5 soft that had ballooning. Should I throw them all and buy new? Is it worth the risk for £80-100. Thanks Quote Link to comment Share on other sites More sharing options...
Tug Posted January 7, 2021 Share Posted January 7, 2021 Plug them in to the charger and see what the cells are reading. Anything below 2.7 on any individual cell is ready for disposal. And don't just bin them, you could cause the bin lorry to catch fire. 3 Quote Link to comment Share on other sites More sharing options...

Thanks I'll check the cell voltages, is that the only issue or would being discharged for 4 years cause any detrememt? The other batteries are soaking in heavily salted water now.

Tug Posted January 7, 2021 Share Posted January 7, 2021 You need to ensure they're completely discharged before the salt bath. If they're left at LVC voltage, there's a sizeable risk that they'll deep-discharge in fairly short order. I had it happen overnight, just one night and they were fubar. 1 Quote Link to comment Share on other sites More sharing options...

Voicon Posted January 8, 2021 Author Share Posted January 8, 2021 I dont think my charger has the capability to check cells individually, it shows the total voltage when charging but I can't see anywhere to check the individual cells. It's a Hobbyking eco eight. Quote Link to comment Share on other sites More sharing options...
Tug Posted January 8, 2021 Share Posted January 8, 2021 Scroll through the menu, it'll be there. Probably the button on the far left. Quote Link to comment Share on other sites More sharing options...
