External battery? --newb question

[Zembot]

What is the connector called on the RN battery? I.e., if I were to search online, what type of connector would I search for? I’d like to solder together a male/female cable (about 2’ length) and use an external RN battery when connected to the PC.

I recall a similar post, but now I’m unable to find it.

Thanks

Hi,

Although I haven't tested it yet myself, you might be able to just connect the battery to one of the servo ports on the RoboNova-1 ...

That is a standard way of putting juice into R/C receivers ... just goto the two power 'n ground pin side of the servo connector and leave the signal side empty.

I've been thinking of giving it a test soon myself but haven't actually tried it to see if the CPU gets power or not ... definately the servos would have power though ...

I tried emailing sales at several companies to find the battery connector part number ... never got an answer back ... Tony Ohm suggested one site which I've tried emailing several times ... they don't answer their email ...

They are available from the savvy shop,and are called HV connectors just click on the online shop link under main menu left hand column.

And SubPilot was good enough to give the details in a very early post : So quoting Subpilot

"The power connectors are made by AMP/Tyco and are in their Economy Power line.
The connector P/N is 1-1123722-2 and the pins are 1318912-1. Digikey has them. conn= A30501 pins= A30499."

BTW I agree with CaptKill4Fun, and have used the servo connectors on RC kit myself. My only caution on something like the RN-1 would be the current passed through the servo connector in a servo stall situation. If this is the battery connector this would be the current drain for all stalled servos so could be quite high. Anyway just a thought.

Yeah, it would probably work, but I believe the tracers on the board are pretty thin around the servo rail in comparison to the bat conector/charge/switch's. The amp draw can get up there. I'd be careful... especially since no one has actually tried it yet.
...likewise, just a thought.

Hi,

The HV battery connector in the RoboSavvy shop is a 3-pin connector ... the connector on my RoboNova-1 is a 2-pin connector ???

There is anotehr connector in the shop too, but it still doesn't match the RoboNova-1 ???

What's the part number for this type of image of a RoboNova-1 Battery side connector?

I have checked these do appear to be current the Digikey part no's and AMP/Tyco part no's

Hope this is a bit clearer

Zembot Welcome and sorry for the wrong info.Thanks for stepping in chaps.

[CaptKill4Fun]

Hi,

Thanks Pev ... after poking around with those part numbers I found that Mouser does sell'em and half the price of DigitKey! That's a US$0.28 savings per set!

Anyway, I found the data sheet for the style and it shows they come in different colors too ... White (natural) 1-PN, Yellow 2-PN, Blue 3-PN, Red 4-PN, Black 5-PN and Green 6-PN.

However, I couldn't find colors other than the white at either shop ... but somebody must sell'em ...

Appreciate your help everyone. There’s no way I could have found these connectors on my own. I just placed an order at mouser.com. Thanks for the links Capt.

Now I have another related question. I was ready to order a RN battery to use with the new cable I’ve yet to create. Then I got to thinking… I have several spare C-cell NiMH battery sticks from my RC cars, which I rarely use. I’m confident I can disassemble and re-solder the cells for the correct voltage to use as an external battery. My concern is using 1600 mA cells for the RN? Does a higher mA give longer run time? Or will it fry my RN? The battery amp ratings don’t seem to matter with my RC cars (only voltage), but I definitely want to play it safe with the RN.

Sorry I’m still in the infant stage of learning. Thanks again all.

[bauermech]

The mAh rating translates to runtime for the most part. The more you've got, the better.

[Bullit]

Just don't go over 6V and your robot should be fine with greater mAh. Your robot should run longer if he can carry the extra weight which I'm a little unsure of.

[Zembot]

Thanks for clarifying mAh guys. That's what I thought, but I'd be kicking myself if I fried the RN and didn't ask.

... if he can carry the extra weight which I'm a little unsure of.

Actually it's to have extra external batteries when I have it connected to the PC via a cable to the RN. I'm limited in my knowledge of robobasic. Yeh I know it's easy for everyone else . I'll use a fully charged RN battery just to program a simple move. The external batteries should give me extended PC time, which I desperately need.

Thanks all

hello zem ;

In french sorry

Pour ma part j'utilise un connecteur que tu trouve sur les PC ( un peu comme ceux des ventilateur de cPU), c'est un connecteur 3 pins mais tu le recoupe avec un cutter pour avoir que 2 pins et tu garde le détrompeur !!!

sinon regarde ici : http//www.radiospares.fr

Pour ma part J'ai un adaptateur secteur 6/6.5 V 2500 Ma ( regarde sur ebay il y en a) ou j'ai adapter ce connecteur , je le connecte A LA PLACE de la batterie du RN1 cela me permet de mettre au point mes routines

One idea that I'm looking in to is using mobile phone battries.

there 3.7 lipos with 950mah and weigh 18g

two inline would give the the right V with a regulator. there cheap and you could have a couple charing walst the others charge I might buy 8
