I've bought an after market Yamaha battery

[Chargeride]

Getting it next week, I'll pull it apart if I can, stupidly cheap...

What’s wrong with it, I think you can use it for some time

When I see Ah then I instinctively look for a fire-extinguisher.

When I see Ah then I instinctively look for my Watt Hour Meter,..

I'm guessing that 17ah rating is probably a lie?


There are some pretty good deals out there though,.. like this 200ah 48 volt battery,..

Only $139 CAD, and that includes a charger !!!

I think the fact they've been in business for 16 years gives me a little bit of confidence that they are sourcing quality items.

Even if your battery only lasts a year before it wears out,
(which is what apparently can happen with cheap batteries, but there's almost Never a fire.)

You've still got a battery case with hopefully a proper BMS inside so you can rebuild it with better cells.


Just a battery shell alone for me to build my own Reention Dorado battery is almost $75 CAD.

Plus the BMS,..

Plus I might need the battery indicator/USB circuit board,..

And I'd want to install a BMS pin-out hookup, so I can check and balance each cell group manually,..
I've already got those parts,..

And of course I'd need the lithium ion cells.
I'm thinking Samsung 50E 21700 cells like in my 25ah battery?


I'd do a lot more research before I bought a BMS.
That's one component that I'm not going to cheap out on along with the cells.
I don't want a fancy balancing BMS with an app to go with it.
Just something reliable thats tried and tested.
I'd be doing the cell checking and balancing myself.



I can always set my on if I want to ?? Just plug it directly into house current.
That aughta get er done?
Fires are fun to watch.

Sounds like you don't trust (electro) PAPA.

There's no reason we can't all have an electric flying bicycle that doesn't start on fire.

The flying bike only needs to be powered to get launched.

Once it's in the air, you shut off the motor and travel for free.

What rings the bell is "17 Ah 36 V", which is your usual description for cheap batteries. For some reason good brands talk Wh not Ah/V.

I hope it works for CR but I would have a hard time to believe such a cheap battery would be anything good or safe.

 

[Chargeride]

I would say watt hour is a marketing ploy , they never mention the 36V because that was being used by tool companies to promote power improvements, more volts is good...

Electric cars have done the same because theres a point where more volts starts to look a bit scary.

The new 800 volt Tesla!!!

What!!!!!
