like this




or will i destroy my batteries?

Re: charging in parallel ?

Depends on several parts of the equation.

1) What kind of batteries?
2) if the voltage goes too high, bye bye batteries.
3) in case of smart chargers, forget it. They will make each other believe the battery is full.

1 there nimh batteries custom made from two 7.2 volt sticks which are 5000mah
2 it shouldnt got too high as its in parallel?
3 whats a smart charger? the chargers used to be argos drill chargers

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.

Re: charging in parallel ?

I wouldn't, just buy a decent cheap charger.

£30 for a mains-powered charger with many more options that will be more than sufficient to charge your batteries: http://www.giantshark.co.uk/power-a606- ... 05325.html

Let us know if it worked.

But I have to admit, I'm getting less brave with aging...

If I would do it, I would wear several items of protection.

Re: charging in parallel ?

also instead of a new topic, ive made my own battery with c size cells 10 of them in total and i was wondering on how to cover them? could i use big heat shrink or is there anything else?

Re: charging in parallel ?

A plastic fizzy drink bottle and a heatgun. The Aussie way.

The smallest bottle you can fit the cells in should do nicely.

I will have to remember that one when I need to insulate a big electrical wire temporary
