As the title suggests, I am trying to see if the Dinotte 200L battery pack (AA type) can be modified so more run time can be generated. The Dinotte 200L AA battery pack is simply a 4 AA cell battery holder with a 9 volt type connector.

http://kc-bike.blogspot.com/2007/11/product-review-dinotte-200l-led.html

I have read a write up mentionig that a modification can be achieved by wiring two 4 AA cell battery holder together so a total of 8 AA cell can be used so the result is doubling the run time (please see attached link).

However, my concern is that the 8 AA cell (2 battery pack) might overload the lighting unit (i.e. from 4 AA [1.5V*4=6V] to 8 AA [1.5V*8=12V]). Could anyone please inform me that there is no need for my concern with the above setup? I just do not want to damage the Dinotte 200L unit by overloading it?

Lastly, if the above modification works, won't an 8 AA cell battery pack with a 9 V type connector work as well?

Is there anything special about with the above modification that would allow it to be used on the Dinotte 200L and not a prefabricated 8 AA battery holder?

Thanks for eveyone's input.

You want to wire the 4AA packs in parallel. They RS holder might work, but it's probably serially wired.

Alternatively, just get another 4AA pack and swap it out when the first pack starts to cut out.

it could be made to work if you know what you are doing with wiring, the way that i would do it (trying to put this so that anybody can understand it instead of the technical jargon) is to take the 2 4AA packs and hook them up to the same 9v connector, this way it can pull the power from both packs, but wont pull more than 6 v

(im pretty sure that this would work but if someone else has a better idea please correct me)

To simplify further: Purchase two 4.8 volt packs, Connect the
red wire of one to the red wire of the other. Do the same with the black wires. Now place your connector on the end of these combined wires. Assuming the batteries are 2400mah, you now have a 4800mah 4.8 volt pack. Ifyou purchase an 8 cell pack, it will be 9.6v 2400 pack.

yup exactly what i was saying thanks for clarifying

If you wire exactly as in your second link above, you'll get what you're looking for: same voltage but twice the capacity. An easy and excellent upgrade :thumbsup:

The RS 8 cell holders are wired in series and provide too high of a voltage.

As others have stated, wire 2 four cell holders in parallel.

I just read through that second link you posted, describing the construction of the 2-into-1 battery cable, and I'm not quite sure why he's connecting the red wires (typically the positive wire) from the battery holders to the black wire (typically indicates negative) going to the Dinotte. The key of course is to be sure the (+) and (-) from your modified battery pack is connecting to the correct points on the Dinotte, otherwise you could fry some components in the light.

jim, take a look at all the pics,
you will see the double pack snap connector is in turn connected to another snap connector

Ah, yes....makes perfect sense now. Thanks.
