Battery Chargers

[tuXguy15]

This year our robot drew a lot of current and it killed the batteries when we had to keep recharging them constantly. Also i know that 15 volts wont last longer. My point is that we are not managing our batteries right if we arent getting 15 volts. The 6 amps wont get it there because doing a 6 amp charge does not allow a peak and level type of charge that those types of batteries need. You do 2 amp until it peaks then 4 until it peaks then6 to finish charging it's.
