Re: GoPed electric assist kit

Everybody always has an opinion. Though I understand some of the concerns that have been posted, only real-world experience will reveal if this new product is a success. I have confidence that PMW would not have introduced such a product unless it delivered as promised. The more I look at it Steve, ...

GoPed electric assist kit

GoPed has a new product for bicycles. Its a 400 watt friction drive unit all in one tidy package. Comes with an 8Ah LiPo pack. Wonder how the friction drive will do in wet conditions? Going for about $799 as I understand it. http://www.goped.com/Products/GoBike/default.asp http://www.goped.com/Produ...

Re: what kind of helmets do you guys wear?

Yes, I agree, perhaps not a reasonable argument.

I'll continue to wear my helmet if for no other reason than my own well being and the responsibility I have to my family. Its quick, simple, and inexpensive and might just be the difference between momentary embarrassment and lifelong tragedy someday.

Yikes, some of you will go anywhere to try and support your point. I though this discussion was about bicycle riding and helmets, not ladders, automobile operators/passengers, and staircases... lol

Lots of very good points though.

Re: Even Newer 4 to 24-cell Battery Management System (BMS)

If this has been mentioned previously and I missed it, I apologize but are there any plans in the near future for a turnkey version of this BMS? If so, a LiFePO4 and a LiPo would be great. If no LiPo, maybe at least a LiFePO4 version that can be easily modified for LiPo. Something I don't quit under...

Re: what kind of helmets do you guys wear?

They almost always suffer "impact" to the head. THAT carries implications because we may not realize that does not mean they had any brain injury, or that they would have had a brain injury. The only implication is an impact to the head could lead to a brain injury. I have a fair amount of experien...

Re: UPS Batteries

The AGM batteries I've split open (don't ask) all seemed to be pretty solidly built. They're not like flooded lead acid with plates separated by voids of liquid electrolyte. AGM's have saturated mats that at least offer some support to help keep the plates restrained a bit.

Re: UPS Batteries

BIG differences in the many different brands of AGM batteries out there. Some are intended for long shelf life, others for high discharge rates, still others for high cycle and high DOD use. There is also a lot of junk. B&B is one of the few manufacturers that provide any sort of documentation. I've...

Don't discount the use of the regular silicone spray on the outside of components and wires. Works very well for modest moisture and corrosion protection. Should be repeated every few weeks.

Re: bypassing battery heat sensor - YESA LiFePO4

The temp sensor is a thermistor. They don't usually fail unless physically damaged. Once you figure out the specs, they are very inexpensive to replace but it sounds like it might be a problem elsewhere on the board.
