    NiteRider lithium pack rebuild

    I got a NiteRider Pro-1400-race from REI about a year ago and had one of my two battery packs die.
    I have tear down pictures if anyone is interested .
    The 4400mAhr lithium battery pack has a BMS inside the pack.
    There is a YouTube tear down for a similar style but it can safely be opened with a razor knife and spudgers, just don't go too deep.
    It is a 2S2P lithium pack with 18650's that I will have made up, if I cannot find a pre-made replacement
    BatteriesPlus has a welder that can do this for me inexpensively.
    The BMS has a data wire and NiteRider is known for having a proprietary board outside of the head unit and the board that is inside the battery pack is a NiteRider proprietary board and plugs.
    I have had some experience with RC lithium's and may try to see if I can find a way to keep the small BMS outside of the proprietary pack that they made.
    If anyone else has any experience in rebuilding these packs, please let me know.
    The BMS is usually a pretty robust item, so I think that just replacing the cells should get me back to where I started.

    Yeah, NR does do some interesting things to try to force users into buying replacements directly from them. I got an old dead Minewt to use as a model to design a GoPro adapter for. I tore it down to see how it was built and was surprised to find the CC driver circuit was part of the battery pack and not the light head.

    Hope it's not too windy up there.
    The board on top I thought was the BMS appears to be the LED controller board with the small BMS in the wrapped cell pack.
    Board has Silkscreened 080-223171M, Copper etched 080-22372M labels
    The board has an inductor and some IC's I am sorting out
    CKO T1 46K AP4T microchip ?

    Sure sounds like an LED driver circuit in the battery then. Seems like the Pro series lights are the same as the Minewt in that respect. I've long since tossed the Minewt so can't compare any of your details to the driver it had.

    Still, it should not be too difficult to swap in new cells for the bad ones.
