    48v to 12v step down to power 300-500 watt inverter

    good point but i wanted to be able to use 12v applications too... in fact mostly 12v applications... may need to get a 48v inverter as well though.

    Thank you! I appreciate the kind words. I have purchased a bright led flashlight that clips on the handlebars one of the ones that takes a single 18650. I need to get one of those blinking led tail lights though for sure.

    again. i wasnt whining. i asked if anyone was interested in going in on boards.... you are the only one coming around and slinging insults that are not warranted... if you want to send Riba your whole bank account feel free to do so but otherwise im getting back to sourcing and building these...

    thanks for the info. yea mine is level 3 protection. I will go for the plus when i replace these but it seems like they will likely hold up for a while. I cannot believe the difference these tires make on my bike it is so much more enjoyable to ride.

    My persistence paid off. Thank you for splitting the thread!! Finally something that is logical and not blinded by emotion people taking what I was saying as a personal attack against Riba were wrong. DIY 4 life.

    And why would that be? Are you a mod? Doesn't seem like it. There has been links to boards and components don't think um breaking any rules... Trying to accomplish something if you don't have anything to add you can take a seat.

    destro... im trying to get one together for myself for a reasonable price. I have no intention of taking business away from Riba and selling welders but I dont understand why it would be a problem if he isnt offering them for sale anymore... after i get mine together and test it i will get back...

    So Tom explain to me where im asking anyone to work... I said the exact opposite in kit form sure its worth the cash.... but just reselling boards at a huge markup isnt "working" the work done on this was gleaning info from other resources and putting it together... this welder is not riba's...

    controller mounted next to battery?

    thank you for the reply! thats awesome then maybe theres not much need to worry about them if you arent abusing the heck out of them. i will likely just order a cheap 48v/60v just to have a spare just in case... or if i want to run a little more power. are you running a 1000 watt motor on that...

    JP spot-welder, FET-switched, timed adj. pulse

    I hope no one misinterprets me... I simply want to keep this info and parts available at a reasonable price and since kits arent available and no word on when they will be it seems to me the best thing to do is to make a alternative way to get / sell the parts so people can continue to build...

    controller mounted next to battery?

    Are any of the chinese controllers better than the others? like made with better components... i have a 29 amp controller and 1000w motor... i was thinking about getting one of the 48v / 60v controllers in case i ever want to bump up the juice a bit with another pack in serial. Just curious if...

    So in this thread there is a link to buy 3 boards for 48 bucks but i only need one... I figured since the kits / built units arent being sold anymore i could snag one of the boards cheap... but riba wants 40 for 1 board and a pic. I have a pic programmer so the pic isnt the issue. I totally and...
