    LiPO PSA - How Not to Bun Your House Down

    Morning all (or whatever it is where you are), I had a good scare last night that provided a stark reminder of why we treat LiPO (and all batteries really, but particularly LiPO) with the respect and care we do. Most who read here regularly are generally well aware of the dangers and how to...

    Watt/Ammeter With peak amps and watts for 72v system

    Hey guys, So I recently changed my system from 52v to 72v and I'm having a heck of a time replacing my old wattmeter, a basic bitch, blue 150a turnigy that worked awesome, but sadly is only good up to 60v. Searching for a replacement I was only able to find units with rather large external...

    Running higher voltage and relation to power, amps, resistance, heat...

    Hi, So I've been running my leafbike 1500w at 52v and 80a batt for peaks of 4200w, but I'm wondering if going to 72v would be better? If I run higher voltage I also need to run lower amps to keep the wattage within reasonable bounds correct? This being the case I'm then wondering if that would...

    RC LiPO imbalanced discharge question

    Hey all, So I just got back from a ride where my LVC kicked in only about halfway through my trip and I had to pedal all the way home. This seemed weird, but I was also doing some controller tuning and therefore lots of stop, WOT, stop, readjust, WOT, etc before even getting to the trail. And...

    Reading a 100k thermistor with incompatible controller

    Hey all, So, I routinely push the limits of my leafbike 1500w with FF, running a YKZ7280-JA bluetooth controller, 80a batt, 230a phase (usually tuned down a bit to more like 60a batt, 180a phase, but sometimes not). While I try to be careful, and frequently test motor temperature by hand on the...

    Temporary replacement controller

    Hey fellow nerds, So, I blew my stock leafbike controller (hunk of junk anyway) the other day, went a tad overboard on the old shunt modding, and she peaked out at 80a and 4200w before BANG, extreme cogging, a sure sign of a blown controller. Tried to replace the blown fets with spares I had...

    Balance charging 2 x 7s Lipo

    Hey all, hope this is the right place for this question. Honestly there probably is no right place since I feel like I should have been able to find this information myself. But alas, it was not to be. I'm building a 14s2p 10Ah lipo pack using 7s packs, a fairly rare configuration, which makes...

    Torque of Bafand G60 750w vs. Leaf 35mm 5t

    Hey guys, I've been playing around with the simulator and I'm definitely missing something here. The Bafang g60 750w hub motor is one I already own, and is pretty decent, but I don't see how it can possibly match up with, much less handily beat, the leafbike 1500w 35mm 5t wind, can it? Its...

    48-60v 55A controller paired with 16s 10Ah LiPoly 20c

    Hello all, I have a controller coming that is rated for 48-60v, 55A that I would like to run with a 16s. From what I have learned I don't think this is an issue? The 48-60v rating is nominal right? So even though at full charge my 16s would be 67.2v, it's nominal voltage would be 59.2v. Is this...

    First Build, know what I want, not how to get there.

    Hello all, I currently own a fat bike ebike I got for free as an abandoned package (I work in shipping). Best score ever! It has got me hooked and I've put over 300 miles on it in the just under 3 months I've had it, but now I want more power, and, being a huge nerd, have proceeded to try and...
