    Where to buy headways?

    you could offer the security that each cell was tested and is working as customizeable pakcs are. The austrailian headway importer has his business set up around that fact: some want the best price, but others prever a acceptable price and usable servie and the safety to not receive a maybe...

    Headway Battery rust

    this busbar seems to be the culprit, maybe helped by clorine chemicals ( washing owder, pool equipment, fertilizer...) around the storage area. different types of metal have different values in matters lie magnetism and electrical leading ability, so 2 different types of metals tackled...

    so let´say "Yay" to a surprisingly cheap to run and economic counterpart to conventional electric motors. those still convinced that all ice-type motors are evil compared to a electric should consider the percentage of electric energy lost in transit when transported of the coal and nuclear...

    New Clean Propane Powered Scooter and Fun Kart

    you will have to run these small airtires with considerble pressure to minimize rollin resistance, the hardtire gopeds don´t have this problems and never get a flat. if adding on the weight of the batteries in your backpack ( 10Kg is without batteries which makes it stealthy i assume ) the...

    found new cheap site for BMS, LiFePO4 & charger up to 18000W

    since they make good stuff it doesn´t really matter, but there was a misinformation about the "CE" sign at the beginning of this thread.

    Best damn 6S lithium monitor on the planet for $15

    daisy-chaining of more than the signal to the piezzo-buzzer is not doable with soldering on the board itself only, the other features like displaying more than these 8 physical channels ( limited by avalability of plugs) on one monitor would require hardware modifications too fuzzy to make and...

    Konion 18650V charging? Help?
