This in from another site, about RC electric boating. The poster is a owner of a RC boat shop here in the states. He is a real reputable guy. I have talked with him a lot, and I respect his opinion.
Near Disaster - Chinese battery
That's it! I'm done! No more Turnigy batteries! About three weeks ago I had a small 1800mah 3S pack blow up on my charging bench. No reason for it. BRAND NEW pack. Charging at 1C. I managed to knock it on the floor. All it did was scorch my charger and put smoke crap everywhere.
TWO DAYS AGO I opened my Lipo cabinet in my warehouse/shop to get some packs out. I noticed a strange sticky film on the packs...THEN I SAW IT.... a 4S 5000 40C Turnigy pack, again, brand new and hadn't even been charged, had blown up inside the cabinet which holds about 50 lipo packs! It had to have happened when nobody was there. It scorched some other packs close to it, melting heat shrink and a balance plug on one. I can't imagine why the wooden cabinet and my entire 2000 sq. foot building housing our inventory, workshop, lots of boats and airplanes....to the ground! The warehouse is air conditioned and packs are always reduced to storage charge before putting in the cabinet.
NO MORE Turnigy batteries for me! You guys do what you want but two fires in three weeks from the same manufacturer's brand new packs has me convinced.
I will spend more and only buy quality Hyperion packs only from here on out!
