Well, I dont know if Im the first, but I think I had a battery vent yesterday. It was very hot yesterday and I was running errands. First time it happened, I dont think I knew. I just went to pick ELA up and it was all loose. I thought, this is weird........
I happened again, and thought this is really weird.........
I switched out the battery and all was fine for rest of the day and today. I decided to look at the battery and it looks like there is rust on the flat or neg part of battery. Its an AW IMR 18500. I suspect this was the battery that was in use when I left my ELA running for 45 mins. I thought I threw it away but the other day my mom said she found a battery downstairs and placed it where I have the other batteries, it got put into circulation.
But anyway, I wanted to let you guys know that the ELA does indeed sort of blow loose. I would have to say that its safe and combined with the design, the kick 2 and the AW batteries all went well and nothing or I, got burned , or injured.
