Re: E-Bikers and Dealing with Bicyclists

EV's (electric vehicles) are like women… There's a different style for everyone… :)

Some like smooth and comfy, while others like a "wild ride"… Lolll

You want to be like an Ebike so bad, but how come this post is in the electric scooter and motorcycle general section?

Re: Battery Chargers = plug in the wall, or battery first

So I guess the summary of it all is: 1) cheap chinese chargers can fail at any time from a multitude of reasons, and the "plugging sequence" has very little to do with it.. :) 2) general charger observations are important: EX: vibration damage (if transporting), fan is working properly, used in a dr...

Re: Sinopoly, or winston?

You should first decide if you want to use LifePo4 or Lipo, as they both have different characteristics and safety/fire levels.

There is plenty to look at, EX: discharging C rate, charging C rate, weight, pack size, safety level, charging equipment, indoor/outdoor charging, range, etc…

Re: Battery Chargers = plug in the wall, or battery first

I guess I'm lucky with the sparking as my system is only 48v and only generates a small spark. I guess my question was more related to properly plugging in the chargers to prolong their longevity. I keep hearing about people saying that their chargers only lasted 1 month, or they only used it 10 tim...

Re: Better option: Sunthing 20ah or Ping 15ah?

My personal best from a pingbattery was about 700 cycles. Thing is, your bike won't spend it's entire life in an air conditioned lab. I would likely have gotten more cycles, if I hadn't left the pack in a hot garage so much. Though most of your 64 cells may go more than 1000 cycles, only one needs ...

I have never had any "paper instructions" included with any of these chargers… (cheap chinese chargers)… Here's an excerpt from an eBay ad about a 6amp charger… Read the bottom section in grey. charger instructions.jpg I just wish we had the "real design/engineering manufacturers instruction" IAN.

Amberwolf, I agree with what you are saying, the instructions the heard are on both sides. I thought the "method" of plugging it in had more to do to the "type" of charger ( different switching etc...) What I see on ebay relating to "harder instructions" seems to be mostly "cut & paste text" all say...

Hi Guys, I have two LifePo4 / Lithium-Ion chargers (the cheapie kind) and there is no instructions as to how to plug them in.

Re: Better option: Sunthing 20ah or Ping 15ah?

From all the research on Lifepo4 pouch cells (ex: Ping) and ES members, they say it's 1c and max 2c discharge. From what I've read, >1000 cycles at 80% Dod (.5 c).

Mind you, I haven't seen any manufacturers spec sheets. :(

If I get 5 yrs, or 1000 cycles, I will have gotten my monies worth.

Re: Better option: Sunthing 20ah or Ping 15ah?

I recently bought a 48v 15Ah from SunThing and I am really happy. I took the slow boat delivery to save some money, but it takes 7-8 weeks. Maybe you should splurge on the Air Mail option. I am very happy with the battery as it appears to be a good solid choice. After a few break-in cycles, I was ab...

Re: How to get the smell out ? - Chargers.

I have a couple of these 48v 3amp LifePo4 chargers that have that "burnt electronics" smell when they are charging. I even took out the infrared temp gun to verify the charger temps and they seemed normal.

The smell is Not Cool, but may likely be the norm…? :(

Re: Battery Space 20AH Prismatic LiFePO4 tests

There are a few different batteries available with similar design of plastic cases and they do suffer from swelling and compression is recommended, although they are physically much larger and so less rigid. It's common to see pallet banding applied to the channels in the cases to provide support. ...

Re: Battery Space 20AH Prismatic LiFePO4 tests

As to compression, I'd say that this is a: 'maybe'... It sure wouldn't hurt.' The plastic cases ARE pretty rigid. If you drop one on your foot it is your foot that will suffer, not the battery. I'd say they are more structurally sound than a typical car battery, due to the relatively thick ridges o...

I don't want to disagree, but I am not so sure about the compression, as the 12 V 20 ah pack that they sell doesn't seem to be under kind of compression?
