Re: Charging batteries in series

...... so series it is then.

Do you normally remove the tiny JST pH connectors and just use crocodile clips to charge or make up adaptors?

I made a charge lead today using JST pH sockets but they are bloody fiddly and probably won't last long. Good soldering practise though.

Re: Charging batteries in series

I understand I asked the question and I do not want to disagree but...

I guess with 2 single cells I can either connect them in series and charge them as a 2 cell battery pack or according to this I can also do them in parallel.

Re: Charging batteries in series

2 cell batteries don't really require balancing. I would advise making the 2 cells a permanent 2-cell pack and charge it as such, because then it means you don't need 2 chargers on the go. My charger comes with a socket to balance 2 cell packs? If I make up a lead to charge in parallel on one charg...

Re: Charging batteries in series

It's not essential to balance charge small battery packs. You can, and it may improve lifetime, but many smaller packs come without a balance connector and are just fine. If you don't want to balance charge you can just connect the red and black 4mm outputs from the charger to the positive and nega...

Re: Charging batteries in series

If you put 2 new cells together as a 7.4v lipo pack, you charge it as such. The charger will not know any different. Wire the 2 cells together as a permanent pack. Then you can get whatever lead you want, solder it to the pack and use the opposite one with Banana plugs on the end that will plug int...

Charging batteries in series

I have just bought a Sky Rc charger http://www.nitroplanes.com/26p-e4-charger.html and 2 x Lipo batteries that I will connect in series to create a 2 cell 7.4v battery. Can someone tell me how to connect these to the charger; should I charge them individually or leave them connected in series? If I ...

Re: New B: First post, First RC, First robot

Items are starting to arrive now, so I have decided to make a mock-up of my design. I have added a link to photo bucket (if it works). http://s380.photobucket.com/user/sportball/media/IMG_20130928_221806.jpg.html I went for the sabertooth in the end to make the first build a bit simpler. I am going ...

Re: New B: First post, First RC, First robot

Thanks for the help and the offer to programme the baby O. I will have a think about it and place the order tomorrow.

Re: Sabertooth alternative

Thanks for the info, I will order a baby O and have a look. I am happy to do some basic soldering as long as I know what to do.

That's the final component then; now I just need to figure out how to wire it all up, programme the transmitter and build the chassis....easy :oops:
