Sounds like a battery issue at first glance, as you EQ a battery it gets warm or even hot and this will effect ability to charge. If e en one of the L-16 is not exactly the same voltage you will not get to EQ untill another battery over voltages to show your overall volts. Need to look at each battery volts under this charge condition. Also if you have a battery acting up be very careful working around them. Jerry
