DON’T FORGET THE MARSHMELLOWS! (e-trike battery fires)

Many of us have electric motors on our trikes. And they require batteries to provide the electrical power to run the motors. Lithium batteries have a deserved reputation of being capable of being quite hazardous, but that does not mean they are particularly dangerous. Never the less, it is important that we know some things about our batteries and understand some basic fundamentals. We should be careful to buy quality lithium cells such as Panasonic and Samsung. The much cheaper batteries likely use no name Chinese cells and with them come an increased chance of something going wrong … especially if the batteries and/or chargers lack good battery manangement electronics built in. Any more, that isn’t much of a concern either. Basically lithium batteries are safe.

The video below shows a battery on a bicycle catching fire and the guy dealing with it. It is quite likely that he did something he should not have done that caused all this.

This man is living dangerously approaching the burning battery that close and spraying water on it. With the explosions taking place it could shoot out and hit him. And as you can see spraying water on a lithium battery is not exactly safe or effective.

This next video educates us some about lithium batteries and helps us to understand “proper battery management”.

BMS … BATTERY MANAGEMENT SYSTEM is the all important element of safe operation. Batteries must be properly managed. Most of us pay no attention to the recommendation to only charge our batteries to 75% instead of fully charging them. The man mentioned fully charging our lithium batteries limits them to only about 300 charges while charging to only 75% will increase their life to around 12,000 charges … some 4 times longer. I have known this for sometime but I admit that I charge my batteries to a full charge everyday. The good news is both the batteries and the chargers have built in BMS to ensure battery safety. In the early daysit was not always so. Things have improved considerably since then.

HOW TO TROUBLESHOOT & FIX ELECTRICAL PROBLEMS ON E-BIKES

I can personally identify with this as last Saturday I started having problems with my e-motor on my trike. Power to the motor keeps cutting out so I need to go thru things in an attempt to find the cause and fix it. I am hoping it will turn out to be something simple and inexpensive but I am fearful that it may be the controller. I have a new battery ordered as my present one is old enough to start showing major concerns. It should be getting near the end of its life. Like many others, I am pretty much on my own as there are no e-bike shops anywhere near me that are experienced and know much about working on e-bike motor systems.

This video is nothing profound … just everyday common sense.

5 BEST RECUMBENT E-TRIKES

I came across this video and found it interesting although I noticed these guys are not doing much pedaling … just using their e-motors to propel them.

NOT ALL E-MOTOR BATTERIES ARE CREATED EQUAL

My first two lithium-ion batteries I bought for my trike after returning a BionX system for a refund were identical batteries which performed the same … about 60 miles on a full charge. I ruined my original battery riding thru flood water that got deeper than I anticipated (DUH!) That was a costly mistake.

Consequently I ordered a third battery to replace my first one. I did not order the same battery I already had. I checked to see what all was available and chose one that looked and sounded good. It has some extra features that I liked. It has a built in taillight and a 5 volt USB port. It also has a docking head on the front end so it simply plugs in to make electrical contact/connection. I assumed that it would be the same performance-wise. I was mistaken. It is rated the same … 48 volt 20aH … but it doesn’t provide 60 miles of riding like my first two batteries. Fully charged 37 miles is “as good as it gets”. From 60 down to 37 … that is quite a difference. Very disappointing. I contacted the seller about this but got nowhere. It charges up to where it should so as far as he is concerned there is nothing wrong with it. Needless to say if and when I buy a 4th battery I will likely get another one like the first two I bought. My second battery I bought now has deteriorated to where it only provides about 37 miles of riding. That happens as batteries age. So I will likely have to replace it at some point in the future. A friend who has a BionX system older than mine (the one I use to have) tells me that his battery is no longer performing like it used to. He can get his BionX battery rebuilt and in doing so it should be better than it was when brand new providing more miles on a full charge as it will increase from 11.6aH to 14aH. BionX batteries were very high priced. He can get it rebuilt for 1/3 of what BionX charged for it new … and, like I said, have a better battery. I can buy a brand new battery for less than what it cost to rebuild it. Well, that is the truth of the matter. I learned in all of this that not all batteries are created equal. Of course, I don’t know how one can possibly know unless others share their experiences … which is what I am doing here. We all want the best quality we can get for our money. I need to go online to write up a review and rating of these batteries so that others will know. To my way of thinking I got ripped off when I bought this third battery and since the seller won’t stand behind what he is selling it doesn’t bother me to rate him poorly. Summer is nearly over. I hope you have been able to get out and …

ENJOY THE RIDE

despite this PLANdemic we are dealing with.
