What 'End user ready ' battery system for e-bike

[NeilP]

I am always getting asked about building/ sorting e-bikes and the battery pack is always the issue

Plenty of build your own options and plenty of choice in the heat shrink wrap style packs like ping or cell man of electric rider etc.

But they all still require some sort of fabrication to fit the packs to the bike , and that is always a pain to do and is not really very end user friendly.

Anyone have any experience with the ready built in a case style packs?..like this one below..and any recomondations of what is good and hat is not?

It's hard to find one that uses a decent cell to start with. A lot of 1.5c rate battery packs.

ebikes.ca is offering packs with 5C samsung cells in them. Bit spendy, but if an end user can afford it, i'd go with those!

 

[NeilP]

Sort of what I am after..but still not quite 'end user ready'

Still need to fabricate some securing method. The GM one I Pictured earlier from Alien Ocean..comes complete with a rack, and sprung terminals. So you fit the rack to the bike, slip the pack in and job done.

Not so much that the 'end user(s) won't be able to plug the andersons in, but more that it still requires extra fabrication to fit the pack to the bike

These are popular in Florida.

They hold these packs.

i have seen pictures of these cases packed with laptop cells and other cells.

They come with sla batteries in them too.

It is easy to replace the sla packs with packs like these.

This case will fit over the whole works.

What about one of those batteries in a falconev ( or other ) frame bag? Those are easier to hook up to a bike than a rack, and handling is going to be better as well, plus the user will have storage space for other stuff.

Yet all bikes need a rack in the back.

The currie rack holds the batteries down on the sides and you can still use the rack on top and saddlebags too if you want.

And use a frame bag.

That may be the best thing about the trailz.

You can load down that heavy duty rack. It is solid and so is the way it is mounted.

The reason there is not a lot of end user ready packs is because its expensive for anything worth while. They have to make sure its supe safe which cost a lot in R&D.
If I wanted a Plug and play set up I would a pack from get E-bike.CA or Zero bike.

Right ? Ever heard of a Currie battery fire ?

They have more ebikes on the road than anyone ?

Sealed led acid... Has a life expectancy in EV use of <2 years. Weighs a lot and the best price I found it 45.41 a WH ($109 for the pack) Pluss shipping which will be a lot. This pack is 24v (2 lead batteries) and 10Ah so 240 wh. Thats only 3.24 turnigy hard case pacs that cost $21 each ($0.29 a WH) and have a longer shelf life, weigh a LOT less and take up less space and can flow a LOT more current! This is a good example of why there is few GOOD plug and play packs!

Currie has been selling li ion powered bikes and packs for years now.

Surely they have more li ion powered bikes on the road than anyone.

Where are the fires ?

NeilP: Check out this "end user ready" battery. No fabrication at all. "Water bottle style" mounting.

Hogwash, random china co has billion times more bikes on the road than currie.

Heck I've bet you've never even heard of some of the biggest names in the game and the reason is they OEM.

Also don't ever forget the biggest ebike market in the world is domestic China, even if it's mostly SLA.

pro tip
Always go for XLR cannon charge connector port and avoid RCA plugs at all costs

The only pack makers I could recommend are OEM and have high MOQ, so many little crappy ones of ali/tabo/MIC that it's almost worth taking the hit and dealing with a local vendor, best suggestion would be to ask if you can be a wholesaler or buy in lots from them to avoid retail.

Most cheap china BMS units are actually up to the job for charge and balance, they work as they are meant to.

 

[etriker]

I was thinking US Florida I guess. Lots of them down here !

I have not been to China. I heard they mostly like sla for ebikes and don't like to pedal ?

All Curries come from China ?

I bought some of these to try for balance connector connections to the pack.

Have not tried them yet.

I am building 12v packs now with 4s and these have the 5 pins needed.

 

[t3sla]

It's a sea of single freewheel, plastic ridden, sla weighted, five people to a bike insanity where you see riders get mowed down by cars as if it were frogger.

Some of the people I know move 300K units a year out just a few shops, they have these peak waves of insanity where they are just hiring people off the street to deal with surge demand.

Mind you these things sell for less than you'd spend on bike lipo, like way less

Also don't forget there is a euro market, this thing i absolutely love about the euro ebike market is they won't even bother buying china after market compatible batteries for their bosh/Panasonic pedelecs, I mean you have to admire that kind of consumer.

If you are looking for a simple rack based solution looks for cheap look towards the china oem rack battery solution for pedelecs, they really cap out at 36V but you can different cells like the high discharge Panasonic CH range which might give you 30A cont

EDIT:
Nice job on the 5pin XLR connectors, i've only dealt with the 3A ones myself.
Myabe build it so that it's one solid chunk for the battery medic and the XLR connector so u just shove it in without dangle

 

[999zip999]

what is this battery for 24v or 48v for 15 amps or 30amps ? Need help filling in the blanks.

 

[KevXR]

Looking for an inexpensive 36v battery pack that takes no more care than an iPod. For my son with little technical expertise.

BMS offers the Battery Bottle, which comes in 3 similar offerings for 36v. (I did see that BMS Batter warning)
8 ah, 8.8ah, and 10.4ah. Same container, so I would guess different batteries?

BMSBattery's batteries are far from being trouble/maintenance free.

Oh, it broke after 2 weeks? how about you pay $150 to send it back to China so we can send you another broken one? :lol:

So many posts are about going faster, faster, faster. This is about basic transportation and getting into ebikes.
I know everyone likes LiPO. A battery that needs balancing and could more easily catch on fire is not an option.
This is for a kid that can plug in the batter to get recharged and that is about it. Don't expect battery management.

I understand you get what you pay for and I've had some less than happy experiences buying off of eBay. (Return an item to China for $80 to get a $50 refund. Thanks eBay. It would be cheaper for me to drive to your headquarters.)

Alternatives would be appreciated.

The 10.4ah Bottle battery is $179. I still don't know what shipping will cost. I'm guessing a $300 cost by the time I install it.

 

[chunder123]

these metal battery cases tend to be heavy at 1.8kg. your better off using battery with epoxy board and heatshrink.

 

[999zip999]

There is a need to make to strong enough for an ebike. Plus the biggest problem is too cheap of cells so you pay for them to get them.

EM3ev now sells frame mount packs that come with high quality cells. http://em3ev.com/store/index.php?route=product/product&path=35&product_id=161
