I have been wanting to get a 72 volt battery for my current e-motor as that is what it is rated at. I only have 48 volt batteries. After quite a long period of time using the lower voltage I ordered a 72 volt 40 aH battery which they showed as being just slightly smaller that my 48 volt batteries. I questioned how this could be, but I took their word for it and ordered it. It only took 3 or 4 days to get it. When I saw the size of the box I got concerned. When I opened the box and saw the battery my thought was OH NO! This thing is NOT AS ADVERTISED. It is about 4 times as large as the dimensions they gave. None of their dimensions are right. I would have loved to be able to use it but there is just no way to mount it on my trike. It is just too big. It would probably be fine in a velocar or a custom made quad or something such built with using it in mind. Anyway, I am returning it for a refund and start over in my quest for a 72 volt battery. For sure I won’t be looking for a high aH rating … probably 20 aH at the most.

If I were a much younger man and still had my welding shop I would probably keep the monstrous battery and build a quad around it. I would use larger wheels and tires making it able to be used off road like an ATV. I am sure it would be a great battery to use if there were just a way to haul it. With the power of my motor the thing would probably be a blast to ride.

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 …
