    Could this be an option?

    I recently saw this add for a 10 cell Lipo for R/C models. At 37volt 4.5amp I wondered if it could be used to power a bicycle. It doesn't have the management system of a bicycle battery and a purpose made charger would be needed to balance charge it. Advantages may be price and light weight...

    Chinese LiFePo4 battery concerns

    I wonder if parallel cells could be linked by diode's so the Bms could monitor each cell individually, but then the Bms would be much more costly.

    Chinese LiFePo4 battery concerns

    I think your choice of a 5ah pack may have been a wise move as its the only capacity using 5ah cells where each individual cell is monitored by the Bms. In the larger capacity packs, cells are linked in parallel, 2 for 10ah 3 for 15ah and so on. The Bms cannot monitor individual cell's in these...

    Self-build bike nearing completion..couple of questions

    I have the 10ah version of your battery. In the final stages of charging the led's will alternate between red and green until battery is fully charged, when it should remain green. I believe this occurs while cell balancing takes place. The pedelec sensor simply detects the pedals are being...

    Ping battery contents?

    I've recently purchased cells from Ping to repair a 20ah pack originally supplied by him. The cell's are faintly marked on one side with the name SIGNALAB in dotted lettering which is only visible once cell is removed from the pack. The circuit board of the Bms also bears the same manufacturers...

    poor result from new battery

    Bms sounds ok if cutting at 34volt. Not sure who you purchased from but if Daoji666 on ebay you'll need get a returns number before shipping back. The returns details are on the ebay listing. I've dealt with this guy several time's and don't think you'll have any problems. Unfortunately its an...

    Ping battery help.

    Do any of you Ping battery user's know what the BMS's red led's signify? Had a couple come on shortly before charging completed. I think it may be over voltage on those cell's and BMS is bleeding off the excess but I'm not sure. After charge completed voltage at 40.08v dropping too 40.02v after...

    Cheap Indicators and Horn

    I too have one of these ebay lights. I wired the brake light into one of the brake lever connectors rather than use supplied switch, also changed front led to white and added two extra. Added two extra too rear light also. Front indicator's are naff and beeping is annoying.
