    Gaozhao Charger Investigated (non-OEM from China)

    Well, my Gaozhao Charger charger stopped working the other day. If my multimeter is correct its outputing about 80vdc when it should be doing 60vdc. The first sign of issues was the fan getting much louder than usual. Maybe getting to much voltage. The last time it did anything when...

    Battery Care

    I have a 48v 20amp 16s battery and I want to make it last as long as possible. I've been told that it is best to charge no higher than 80%, is that right. This charger cycles on and off after I believe it has fully charged. Is it just trickle charging or balancing? Basically I'm just after...

    steps to further protect and maintain an ebike kit.

    I think the subject line pretty much explains my what I'm after, but a little back story I have a ebike kit installed and running well. With the amount of riding I plan on doing it's only a matter of time before I get caught in the rain. What can I do to weatherproof my kit?

    How fast?

    I would like to rely on it as a primary means of transportation. I also want to be able to drive on any road in my city without slowing the flow of traffic. What do you think the best route would be for a 55 mph ebike build?

    How fast?

    Seems like it would be easier and cheaper to just buy a bike chassis with everything but the engine components in the 250cc size range. Any thoughts?

    How fast?

    What is the fastest you would recommend going on this trek k3500? I'm looking for a bike for a future build that can handle up to 55mphs. If you can, post pics of examples of what I should look for in a bike to go 55mph with.

    What kit should I get and where should I get it?

    Would you say it just sucks because of the shipping cost or performance also? because I checked the shipping cost with the dealer and both 700c and 26'' wheels with kit have the same shipping cost.

    Are any versions of lithium batteries safe to charge inside without monitoring them? Where can I find a bms for this kind of setup? I've posted some pix of another guys pack on here and I wish the complete assembly of this pack was on film and a parts list and seller of parts was mentioned...

    Charging batteries safely

    Unfortunately I do not have a fire place but I do have a grill and a fire pit. My only concern is when I'm not at home or around my batteries do I leave them in the grill/pit? Here in Minnesota it gets really hot and really cold. Any suggestions that won't risk burning my house down?
