eZee battery replacement with Hailong or other kind of battery

Post by ezeepzee » Feb 14 2019 10:00pm

Hi

I have an old eZee Sprint. I think it was the first one ever built. It has no LEDs, gauges, switches, or displays. It has a battery, a motor, a controller, and a thumb throttle. I bought it used a few months ago. And I like it.

It has a steel frame and a rear roller brake that is bad and I want to put disc brakes on it so I probably will have to have eyelets welded on it. Two bike mechanics refuse to fix it.

I am looking into converting it to a dual drive bike. Because it cannot go up some of the 15% hills around me. They are short city canyon hills but steep. I do not go over 10 mph. Going up short steep hills slowly is what I want to do. At this point I do not want a mid-drive motor because if the chain breaks I cannot fix the bike on the road. AAA will only pick me up within 10 miles of my home. I really want a three motor bike system. A front hub, a middle body (I hope this one will last), and a rear hub.

I am thinking about getting a MXUS rear direct drive hub 48v motor from Grin that can take a cassette so I can get a low gear because I am old and handicap (bad leg). I would get it with the fluid and the fins, because going up hills slowly will make a lot heat.

I would like to replace the 36 volt battery with a 48 volt battery. The controller on the bike is a 48 voltage controller. With a low-voltage cut off of 35 V on a 36v battery. The battery when new was rated at 15 aH. I did a load test on it and it comes in around 7 aH when tested from 42 to 35 V at 5 A. ie 1 1/2 hours at 5 amps.

So it has more power but less range than the original controller. The bike used to be a delivery bike for an ebike shop. So I assume they wanted to get to somewhere near but fast.

Has anyone here replaced the battery on an eZee with a non eZee battery, something like these:
