I have a few old electric bicycles: 2 E-ZIP (about 10 years old), EVGLOBAL, and an Extreme Folding XB-310, all of them 24 Volt ebikes. I have been going thru the bicycle components: new Slime Tubes, Slime Tube protectors; truing the wheels; greasing the headtubes, axle bearings; etc. and having fun playing bicycle mechanic. I have obtained a couple of new controllers, have read hundreds of posts about ebikes, controllers, motors, etc. and am enjoying learning different new technologies in my retirement.
Now to the Subject line of my post. I am familiar with 18650 batteries and the different configurations that are possible with them. However, when I started playing with the e-bikes, I bought 12 LOWES Kobalt 1.5 AMP/H batteries, made a small 3-D printer adapter and have hooked up from one to 8 batteries in parallel to run the ebikes (one battery for testing and up to eight for riding around).
The batteries weight less than a pound each and I own three chargers and usually can recharge each one of them in less than 30 minutes. I have used different containers on the back rack, initially a Dollar Tree shoe box, then a small picnic container from Walmart, then a large picnic container from Walmart, then a Stanley Tool Box
When I purchased the 1.5 AMP/H batteries they cost $10 so the cost for an 8 battery 12 AMP/H ebike battery was 80 dollars, now that LOWES no longer sell the 1.5 AMP/H and only sell the 2 AMP/H the cost for a 6 battery 12 AMP/H ebike battery is a 120 dollars. There is also a 3 year guarantee on the battery.
The batteries can also be put into series for 48 to 96 volts, the downside being that the packaging for the Kobalt battery begins to be much larger than 18650's put together for the same voltage.
Now to my question and having read lots of posts on this forum, I know that I am opening a can of worms, but here goes.
What down sides do you see to running the 24 volt ebikes on multiple Kobalt batteries?
What is the up side?
Does anyone see potential danger?
Anything else you wish to comment on?
Thanks
