ok the questions i have is the truck is a redcat exp pro it had a 7.2 nimh battery with a 45 amp splashproof ecs and a 3300kv brushless . sensorless motor well my son wanted to get a batttery that would last longer as the nimh battery that came with the truck was only a 2000 mah battery so he decided to buy a 5800 lipo battery and he bought a lipo battery charger when the battery came in it had 3 holes on one end of the battery one was+ one was - and a small hole in between them we also got a wire plug that had a red wire with a pointed prong on it and a black wire with a prong on it and a blue wire with a small prong on it so i plugged the black wire into the - and the red wire into the + and the blue wire into the small hole between the + and the - not sure what the blue wire is for any way there was a little white plug attached to this which is where the battery pluggs into the charger the original nimh battery had just a bannana plug on it with red and a black wire comming off of it the new battery didnt have any way to attach the battery to the car so i decided that the box with two other pluggs in it we could attach the white plug(the plug to charge the battery with) into there which i later found out it was the receiver box which was a bad choice as it started to smoke so i unpluged it and then the truck would not do anything when i finaly got the battery hooked up to the car correctly with 4 mm bannana plug it did nothing so i assumed that i had smoked the receiver card so i bought a new receiver card and still nothing works i did some checking and there is no power to the receiver from the esc so i am assuming that i need a new esc so here is my questions i need help with

1= the orginal battery was a nimh 7.2 volt and the new battery i got was a 7.4 lipo will the 7.4 lipo battery hurt any thing since its just 0.2 volts difference

2= is the esc that is in the truck thats possible burned up is a 45 amp brushless sensorless can i put a higher amp esc in it with out hurting anything as long as it is still for a brushless sensorless esc or do i need to install the same 45 amp esc back in it</p><div class="_1yr"></div><div class="_sq"></div><div class="_2oy hidden_elem"></div>
