Re: How to weatherproof bullet connectors?

Maybe , unlike you, they expect customers will want to disconnect the harness at some time in the future ? But it doesnt take a genius to consider that possibility ! Maybe there's another connector in the line that's supposed to be connected and disconnected while the bullet connectors are only the...

Yeah, I guess the companies like EM3EV and Tongsheng who put out wiring harnesses using these connectors are a bunch of idiots, unlike the geniuses here.

Re: How to weatherproof bullet connectors?

If Its never going to be disconnected, skip using bullet connectors. Crimp or splice solder the wires, then liquid insulator or hot melt . You can buy commercial waterproof connectors for splicing wires. Bullets + shrink wrap are not waterproof. That's how the wires come. I don't want to spend time...

How to weatherproof bullet connectors?

Total noob question, but any suggestions on how to weatherproof these if they'll never need to be disconnected? I'm thinking a little dielectric grease then heat shrink tubing. Or should I skip the grease?

Re: DIY vs. Commercial: How/ Why(not)?

Relax, John. Casainho is okay. I got annoyed with all the software development discussions he poured into the general TSDZ2 topic, but the open source firmware is legit and they've all put a lot of work into it. If he thinks that firmware is great (and quite a few users seem to agree), then he can b...

Re: 1.7kg 1000w mid drive

One thing that concerns me is the drive sprocket. It appears to be a custom-made sprocket, which means that it could be made obsolete by the company one day if they move on to newer products, or spares would be unavailable if the company goes out of business. Without that sprocket, the entire drive ...

Has anyone actually used any of these and had a battery fire contained by the pouch? I know one practice is to charge inside a steel ammo can, but it's hard to find one of those big enough for larger battery packs.

Re: Voloci E-Bike Liquidation

I had a Voloci back in the day. Decent speed, but the range was pretty bad with the NiMH battery. It was no fun to have the motor shut down right in the middle of a turn on a busy street. Should be better if you can rip the battery pack apart and rebuild it with lithium cells and the necessary elect...

Re: Any suggestions for reliable battery supplier?

Thanks. Now Luna is back in consideration. And of course, just when I wrote that they no longer seem to have the 14AH pack, they're back in stock. It may or may not actually meet the claimed 50A spec, but since I'm only considering a ~750w kit, even if it's off by 50%, it should be plenty.

Re: Any suggestions for reliable battery supplier?

Well, I'm not picky. This won't be for a very high power kit. Just looking for a supplier so I can peruse the selection on their website. I've seen people say not to use Alibaba/Aliexpress and for some reason, there seems to be a lot of hate for Luna around here, so I'm looking for other options.

Interested in a 18650 battery pack, 52v, at least 12AH but not too much more. Looking for something not outrageously priced, under $700. I'll be carrying the pack in a seat bag, so don't need a dolphin case. I rather like how small and light Luna's Mighty Mini Cube is. They used to have a 14AH versi...

But it does need to be "self-propelled" to meet the definition of "motor assisted scooter". No, it doesn't. The statute says it has to have "the ability to be propelled by human power alone."

The advantage of a gas engine is the 300 mile range he wanted without needing several thousand dollars worth of batteries or the hours to recharge them between rides. Piece of cake to pour more gas into the motor in a minute and get going again. For distances of up to 50 miles or so, an electric mot...
