HI every one
Had a big problem with the Engel Gato i put the sub on charge with a very good charger, to cut a long story short was in the garage at the time and the charger switched off every thing seemed to be fine, so i unpluged the charger and put the cover back over the sub to take it out the next day. i then went up stairs to bed but when i came to it the next day when i pulled the cover off every thing was black inside the sub, what had happened during the nigh one of the batterys exploded. Three of the cells all the insides just blow out nothing shorted out in the sub all i can say is what a mess it was i was very lucky that there was a alloy plate sat above the batterie packs. That was the only thing that stoppted the sub from catching fire.
You have never seen anything in such a mess i have been on weeks sorting it out but it is all back together now last thing to do is trim it back up. The odd thing is i remember switching off the charger looking at the LCD display and every thing was fine. I had some of the same make of cells in another unit and when i came to charger it the charger came up with fault and the batterys had just died and they was not even plugged into anything, im not going to say what cells they are but i will say that i will not buy any more
I was very lucky that the garage did'nt burn down and the big sub with it, so it just goes to show how dangerous it can be charging batterys
All the best Sub John
