Ok so I have my sv27 and I ran the boat today,and it ran for about 5-8 mins,when I ran it for the 1st time it didn't run much longer than that...about 10-12 mins? is this normal,I have the PROPHET PLUS CHARGER.Amps Meter=4.73-5.00 AMPS?, VOLTMETER SAYS*ANYWHERE FROM 8.00-9.4 VOLTS? I dont know what the deal is.so I called someone up and they said to charge them at a 1 amp rateto see if they will improve the runtime will it?(when the batteries said they were done,tonight...it said it only charged 1274 MAH? when I charged them today to a full charge*HEARD THE BEEP!* so what could possibly be the problem!?? Thanks!
