Help with Batteries and chargers.

[ryanvm777]

Ok I think I am going to need some help. I have 18 GP 3300's and they died on me. I am getting less than 2 min. of run time and the truck is driving slow.

1. Can I save them, or bring them back from the dead? They cost to much money to just trash them.

2. What charger or chargers should I get? Keep in mine this is for an E-maxx with 18 cells. So I would need 2 chargers that can charge 9 cells or more. Or a dual charger. I dont want to spend to much money (I always say that). If I have to buy two chargers It can be prety pricey.

3. What settings or do I charge each 9 (and mabey 8) cell pack at? I have 2 MRC 959 right now. They say they chare 1-8 cells, but I have been chargeing 9 cells. Mabey this is why they died on me. I have been charging them at the maximum settings and it takes about 30 minutes. The settings are; 4.5 amps charge rate. and I think 50mv cut off or something. Not sure what the mv are suppost to be for 9 cells (or 8).

4. What should 9 (or 8) cells peak charge read? How many volts should a full charge read?

5. What is the max amps I should charge a 9 (or 8) cell pack at.

I need to have a better understanding becuase now I have to buy 18 more cells and more than likely 2 new chargers. I love to drive my truck but I hate waiting 30 min for less than 10 min of fun. Please help.
