William,

I'm all over it!!! Thanks for the heads up........ Greg

It comes with three cords with clips, ring terminals, and a car plug. Each connects to the charger with a polarized plug. I plan to replace the ring terminals with banana plugs. Also has polarity protection. The 1 amp rate should be fine for the 7 amp batteries. I think I had seen mention of Walmart chargers in the area of $35 but $15 seemed reasonable to get now.

hi all

i won an auction on ebay and now have a thunder power poly charger 425 model. it has a cell number button, a current button and a voltage button. and a start/full button. when you start a blue light blinks quickly. but some times i hear an audible cherping and sometimes i dont. if this charger is working correctly what will i see and hear and what does it mean?This charger came with no documentation but i do recall someone telling me that it would automatically decide on the number of cells if you do not. I charged a 1320 ahh 3 cell pack and noticed the super bright led .sometimes they blink and sometimes the cell count led will walk back and forth alternating between 4cell and 3 cell I havent a clue what any of this means or even if it is working correctly . what would the max current you could hit the batterys in order to charge the packs in the shortest time. and also the safetest way to charge

The wall chargers do work fine on those, and it is tough to overcharge using those..... The last time I needed to charge my flight box I tried the feature on the "Triton", and ya know.... that GelCell has never worked better... that was about 3months ago too... it FULLY charged my batt and then just shuts off.. there's a good charger for ya.. charges anything battery on the market. :)
