Boe-Boost Battery Extender

I bought the 5 Cell Battery pack plus the single battery extender, Boe-Boost. The problem is the Boe-boost, has anyone actually got that thing inserted into the battery pack? So far, it has been a frustrating exercise in futility.

    What kind of batteries are you using? I think the Boe-Boost was mainly intended for adding a fifth cell to the standard 4 cell battery pack so that you could still get 6 volts when using rechargeable (1.2 volt) batteries. You may not need it if you have the 5 cell pack. I think the fit is going to be pretty tight anyway. The BOE-Boost pdf says you need to push the two batteries in at the same time as the Boe-boost board.

    Thank you for the reply. I'm using rechargeable 1.2 AAs. I purchased the 5-cell and the boe-boost based on the following from the parallax documentation: Rechargeable Options
    The thrifty Boe-Boost (#30078) allows you to add another cell in series with a 4-cell or 5-cell pack. Adding a 6th 1.2 V AA rechargeable cell to a 5-cell pack will supply 6 x 1.2 = 7.2 V.

    It's been awhile since I've used my Boe-Boost and it was really difficult to get it to fit with rechargeable batteries (apparently many rechargeable are larger than normal alkaline).
    IIRC, I ended up pushing both the two battery ends which connect to the Boe-Boost(BB) and the BB tabs into the other other pack all at the same time. It was a trick but I got it to work.

    I think the BB would be easier to use on non-rechargeable cells.

    Edit: Sorry Rick, I hadn't read you're post carefully enough. I'm glad my method agrees with the pdf.

    Yes, that's the correct way to do it. If you install the batteries first, it will be very difficult to squeeze the Boe-Boost into place. BTW, it needs to be a tight fit to keep the Boe-Boost from falling out when the battery holder is inverted.

    Also, the Boe-Boost was designed aournd the four-cell battery holder. If the cells in the five-cell holder are closer together, the Boe-Boost tab spacing may not be optimum, so reports from the field are welcome on this point.
