    SUITABLE FULL SUSPENSION FRAMES?

    People! Posting negative things about others posts, with zero reference or proof of your negative statement is an inferior trait. My bike hauls ass, is tight in the corners, and rides very good. Just another negatively oriented comment with zero basis in reality. I just looked on Ebay and there...

    SUITABLE FULL SUSPENSION FRAMES?

    Late 1990s GT LTS1 LTS2 LTS3 frames have a full front triangle for a battery box. They came in 4 sizes. A 14.5, a 16, an 18, and a 20". This refers to the seat post length. The 20 inch long seat post version is best because it has the largest triangle up front. I really like the "4 link" rear...

    $14.99 72v Sunwin Controller

    It only gets warm, not even hot. It is directly in front of my rear tire, so it is basically fan cooled. Also. It seems that only the 72v and higher versions are guaranteed to have the 100v 330w FETs I listed in the first post of this thread. Lower voltage versions seem to have the 75V FETs. I...

    $14.99 72v Sunwin Controller

    People are way off in their amperage ratings. I have ran 90 amps through my 15 FET controller daily with videos to prove it. They are the China 100v FETs I mentioned in my first post, and are rated for less power and with a higher on resistance than a 4110. I am powering a MXUS 4t with 20AH of...

    $14.99 72v Sunwin Controller

    Keep watching. I have 3 here that I got all this summer for the opening bid. Right now there are none up, but they have this here better controller with 18 FETS for $35 delivered. Here ya go...

    $14.99 72v Sunwin Controller

    Well, this controller handles 6400 watt intermittent and barely gets warm. I put a 100 amp breaker and pulled 90 amps for over 2 seconds so far. I call this a winner for $23.99 delivered from China within 3 weeks. No better deal that I can find.

    Recommendations for a good soldering iron to buy

    Well it looks like you bought a well reviewed iron. That can solder sheet metal too. To the spot welder guy trolling a 18650 soldering thread... Nothing happens to the chemicals in 18650 cells when soldered properly. You can suggest and imply that there is unseen internal chemical damage all...

    Recommendations for a good soldering iron to buy

    If you read my post, I say that I use my d550 for heavy soldering like 18650 packs, and the station for general bench soldering. I did not imply that the Hexacon is for soldering 18650 packs power connections. Nor did I imply that the Portasol is to be used for 18650 packs. I included the...

    Unknown Contoller

    I bought one and used it on my friends trike I built for him. The controller comes with the jumper plug included to use without an LCD. To turn on and set regen braking, to set the number of motor magnet poles, to set PAS assist, and several other important parameters, the LCD is needed. It...

    Unknown Contoller

    That looks like this Hallomotor/Conhismotor unit. Correct current as 13.88 amps at 36v is 500w. It can be used fine without an LCD. You have to jump two wires as pictured. http://www.hallomotor.com/36v-500w-brushless-dc-sine-wave-ebike-controller-regenerative-function.html

    Recommendations for a good soldering iron to buy

    Here is what I use to build 18650 packs. I use it to solder many other heavy connections on my Ebike. This is the lowest price on Ebay for one of these right now. The second link is the iron I use. I like my old Hexacon station. That is for all general duty bench soldering. I also have an old...

    18650 pre-made or diy?

    You do not "need" a spot welder, as I have soldered all my packs with a Weller D550. You also need thin wires and xh connectors for battery balancing leads. You will need Gorilla/duct tape and heat shrink. If I am making an odd shaped pack to fit in a triangle etc, I use a hot glue gun to stack...

    Arc Burn!

    Well I personally would be getting some XT90s along with an anti spark XT90S, or at least slide the Andersons together into pos/neg pairs. But if your personality is one of needing drama like you seem to indicate, then use all black wires and heat shrink(sarcasm). Anderson 45s at 150v huh? Must...

    Definitive Tests on the Heating and Cooling of Hub Motors

    I am on board for the in the field FF testing. I have a new MXUS 4t that I have not used ATF in yet, but have beefed the wires. I am waiting on a 100a breaker so I can hit 7000w peak. I will watch for the post on how you will distribute the FF syringes. I suppose via Paypal. I am still curious...

    Torque Arm missing - is this a problem?

    I would say to use it, as it could "possibly" spread the axle slot without it, and it will "not" fail in that manner with it. No brainer if you look at it that way. And, the fact that the kit came with one makes me ask...... Has your bike store ever installed an ebike kit before? That seems...

    $14.99 72v Sunwin Controller

    I took a video and it looks like the breaker tripped at 80a and not 100a as listed on the breaker. Here is a video of this controller in action. All I did was solder up the shunt. In the video I pop the breaker as the screen showed 80a. I have a 100 amp breaker on the way. This 15 FET controller...

    Amps seem to dwindle off WOT, 18fet programmed wrong? (pics)

    If you are not slowing down once you reach top speed, then it is normal falling off of current as load decreases at top speed. You see, there is no more accelerating that needs to be done, only maintaining the speed you just accelerated to. Holding the tire off the ground will not reveal any...

    Here is a video of me riding the bike while monitoring the power real time with a camera. This helped me to see that the breaker was tripping right at 80 amps and not 100 as I had thought(and is written on the breaker). I have a 100 amp breaker coming. I also was monitoring the new 10 year old...

    Amps seem to dwindle off WOT, 18fet programmed wrong? (pics)

    It is normal for current to fall off at WOT as the motor speed maxes out due to the voltage ceiling. Instead of accelerating, you are only holding a constant speed which takes much less energy to do. Same as in a car, it takes way more gas to accelerate to freeway speed than to hold a steady...

    HKsunwin is the seller. Search for "controller" in their items. The lowest price one is usually a 72v 500w one for $14.99 opening bid. It seems like these might be refurbs, because my newest one has obviously had 2 caps replaced because they left the silastic from the previous caps on the board...

    $14.99 72v Sunwin Controller

    It saw 100 amps only long enough to trip the breaker, which is pretty instantaneous. I have no bms. I know that I hovered just below that for a while though. I had just installed this controller in my new build with a MXUT 3000 4t and 18s of Multistar LiPos. I pulled it tonight and cut out the...

    $14.99 72v Sunwin Controller

    So, this controller is a real sleeper. I figured that since the output was set at 7 amps, I would solder the shunt up all the way. Oops. I put it on my bike today and it drew over 100 amps peak at 72v and barely got it warm. It tripped my 80 amp(100a trip) breaker, so I stopped giving it full...
