My question is.. can I use lithium ion battery instead of NiMH in my 48 volt
e-bike I do get they charge different I intend on charging out of the bike and put the battery back in the bike to run the bike. does anyone see any potential problems it is my understanding that the lithium ion will give me better performance

 

Welcome to AAC.
I don't see any problem using Li ion batteries in that application. Be sure they are rated for the continuous discharge current needed. Also, I am sure you are aware of the voltage difference per cell.

Frankly, I am a little surprised NiMH work in that application. I always have associated them with lower current delivery than NiCd, LiPo, or Li ion.

How are you going to connect the cells together?

There is a 48 volt li on battery pack with charger on Amazon. An the battery I'm currently using is 48 volt gel 4*12 volts I find they just don't last

Sorry here is a link https://m.ebay.com/itm/48V-Volt-Ebi...argeable-Battery-14Ah-1000W-Set-/162690489854 to the one I was thinking of buying and modifying the mount and just plug it in the same battery input Port that is on my e-bike. My most important question will I get the same result as https://www.amazon.ca/gp/aw/d/B0119...12+battery&dpPl=1&dpID=41Toe69dARL&ref=plSrch

Just to add my ebike-is a 300/500 watt motor

 

That answers my questions. If it is rated at 1000 W, that should be fine.

 

So to understand if I bought the Lithium from ebay I should be good to go. I do understand the wiring will be different and the charging will be different that is why I will charge it independent of the bikes charge system. And then just plug straight into the old battery pack input port when I'm ready to use.im just wondering if pound for pound if switching to lithium is a good choice seen as the lead acid don't seem to last.

 

I think so, if the eBay product is not a fake. I would never bet my reputation on an eBay seller. The claimed ratings, however, should be OK.

Lithium batteries can be pretty dangerous if you don't do it right - but if you go for a suitably rated commercial charger, you should be fine.

If you go for fast charging - don't do it indoors.

 

Thanks for your time and help your answers and of good help thanks

 

Do you have a connection to Li ion battery in Canada I'm looking for a 48volt 10-15 amp hour cell with charger for e-bike

 

What is the style of ebike? Is it a scooter or open frame bicycle?
How far do you expect to travel on a single charge?
E-scooters tend to use sealed lead-acid batteries (SLAB) because of the lower price.
A set of four 12V 8Ah SLAB will cost about $200 and will last for about 3 years.
36V lithium-ion batteries for ebikes run about $600-$800 and will last for about 5 years.

Where in Canada are you located? Have you tried Daymak?

 

Yes I tried daymak and other after markets just thought you might have a source
Thanks for the help

 

Hi guys back with a new question for my application which is better Li-ion
Or li-po .thanks

you've pretty much reached the point where you need to download data sheets and decide which one is best suited to the results you want to get.

 

What bothers me is that the first battery is a gel battery. Normally they give different life for gel batteries, depending on to what percentage you discharge them. I think this may be the reason they go so fast. If you discharge the Li-Ion battery too much, it will go fast also.

How many charge/discharge cycles did the NiMH one last (maybe 500)?

If the charger for the bike NiMH is on the bike, you will have to disconnect it somehow in order to avoid damaging the battery.

 

Hi Mike,

Let me introduce you to Battery University. It has been around awhile and is revised relatively frequently. It is reliable. The first link below is to its home page. The other two links are searches I did that I hope are on topic for your questions.

Its usual to use UVLO controlled power management with lithium, but my E-cigs are entirely salvaged batteries - many of which were dead flat when I rescued them. but then I don't complain much about short life on stuff I got for free.

Depends on what you are looking for: Safety, longevity, cost, performance, etc..
In general:
Li-ion and Li-po are more or less the same from an end user standpoint.
Although, Li-polymer types come in pouch cells, and can have higher energy density than li-ion cells. Therefore, you can achieve better power/energy to weight ratio.
I would say it depends on the chemistry the battery manufacturer is using and who they are sourcing their cells from.
Make sure you don't get some knock-off garbage.

I'd add that the pouches are a little less robust - but the steel jackets are more entertaining when they build up a head of steam.
