Re: Price check on battery packs

For USA shipments, is HK still the go to store, what others offer good quality, pricing, and service for US delivery?

Re: Yescomusa.com 500 & 1000 watt 48v rear kit review

Well, I just hit 6 years and ~22,000 miles on the 48V 1000W yescom motor Wes, That is simply amazing. Due to your diligent and regular reporting, the decision to go with this motor was super. Not putting anywhere as many miles on it, working perfectly. Only issue is the electrical connection betwee...

mcintyretj, As always, very much appreciate the regular updates, although they are getting somewhat boring :) That is your kit just works like a mule.

Re: Yescomusa.com 500 & 1000 watt 48v rear kit review

Thanks guys about the rear axle torque. The frame is 6061 so may need to get torque arms. For now I set the torque to about 60. It clicked at 50 but not 70 without feeling like it was going to strip. Will see if it holds. The 15s 10amp HK LiPo battery pack is delivering 20 miles or so, up/down, har...

Re: Friction drive outrunner setup. New DJ bike.

welcome aboard. If you have no other option then just do it. Just make sure you have the motor pressed onto the tire so there is no slippage. At worst case, you are out a motor but in this game this cost is not much of the total bill. I don't have personal real world experience with FD drive but I d...

Re: Yescomusa.com 500 & 1000 watt 48v rear kit review

Rear axle turning issues. How much torque do you use on the 1000w rear hub axle nuts? There was a mention of 100 ft/lbs torque. I have a torque wrench to screw to 100 ft/lbs but it seems like the axle shaft will split. A torque arm is not visible on the bike in the pics but is there another way to l...

Re: Which gear in a 3 speed hub is strongest?

Since the sun gear on the shaft was identified as a failure point, did anyone source a gear that had more strength? Any other mods that resulted in improved strength?

Re: Posturing and Rants on the Rear End of Things

Very old thread but wondering what the current experiences are with durability of the SA 3 speed hubs and damping to reduce gear stress. Did anybody do any mods to the internal IGH parts to reduce weak failure points? What is the upper wattage/torque limits to keep from blowing it up? thx

Modded IGHs?

I bet plenty on a beer(ish) budget would line up for a 3-speed IGH capable of 3-6 kW. The SA AW and Nexus 3 speed units seem capable donors. So many tinkerers here but very few stories about mods to IGH to increase strength. What's causing failure in high power applications? Seems like two primary c...

Re: Help in picking out parts for my first bike

Since you are in Sweden, you should check the legal requirements if you care about that stuff. I think most Euro countries have 250w PAS only systems. That will narrow your selection quite a bit.

Re: Help in picking out parts for my first bike

Welcome. There are many ways to do a ebike. Your bike is quite nice and light so I would suggest you go with a lower power unit. The easiest is to add a rear hub motor. There are kits available that provide the needed parts. You can also purchase a prebuilt battery in a nice container. It would take...

Hi, Love your posts. It is amazing to read about the amount of milage you are able to put on such an inexpensive setup. I took your advice and purchased two Mean Well HLG-240H-30A chargers. I want to double check the wiring needed to get 60V output. I found a couple diagrams but would love it if you...

Re: Yescomusa.com 500 & 1000 watt 48v rear kit review

I got one of the Imax 50 watt chargers thinking it would be good to have to balance charge individual packs should they need an adjustment from time to time. For a 5s 5000mah pack, do I need a more powerful unit? I'm expecting this sort of pack balancing should not be that often so if it takes more ...

Thanks for the confirmation, Wes. Without any manual cell balancing what is the acceptable variance in cell voltage? Mcintyre did a great job of demonstrating easily understood way to make small adjustments. I'm not planning on initially doing any cell balancing; that is why I checked and asked. Fir...

Hi, Again, thanks very much for the guidance. With a regular voltage meter, I checked the voltage of the 6 packs. Four report 19.3v. The two packs other had one low cell each - .9v in one and 1.1v in the other. Does this indicate a bad battery pack and they should be exchanged or does a balancing of...

Thank! I'll add the BMS to the next order. To use this you plug the BMS into each battery pack to check the voltage of each cell. I'd like to get a Meanwell charger as you've had good luck with them. Which one should I purchase that will charge the initial 10a 15s pack and also a 15a 15s pack? This ...
