charging in parallel ?

[maddox10]

1 there nimh batteries custom made from two 7.2 volt sticks which are 5000mah

Big batteries.

2 it shouldnt got too high as its in parallel?

The more volt you give to the battery, the more amps will flow, charging the battery faster. If the chargers don't have the electronics to limit the volts , it is possible that the voltage will get too high.
Otherwise, if the voltage is limited, the amps won't flow as fast as you wish.

Definitly not smart chargers. before connecting the batteries, messure voltage and max amperes. If the chargers don't go up in smoke.
Just to make sure you don't get expensive strings from your batteries.

My advice, buy a Imax B6 or simular as soon you have a few £ to spare. Gives you a lot more safety, and a lot more options in the future to charge batteries.
