Best value 48v 10AH lithium ion battery?

[beastcoast]

Completely new to the electric vehicle game. I'm looking to convert my bike, however all of the quality kits I've seen are wildly expensive. I'm sure that's the nature of the technology at this point in development, but I was hoping to cut down on cost some by purchasing the kit separate from the battery.

I've done a few searches for 48v 10AH lithium ion batteries and I was immediately overwhelmed by information. I was recommended to ask you folk.

sun-thing28 guy and hunk-801 are the cheapest ebay sources of pouch packs because they ship surface freight. but you should buy at least 15Ah minimum.

Which specs has the kit you will get? Also what's the range do You need?

Yeah, can't pick the battery, or even discuss much, till we know what your needs are. 10 ah might not be enough to get you where you want to go, depending on your weight, speed you want to go, etc.

But chances are, 36v 10ah will be enough, we just need to know what the motor kit you choose will require. "1000w" kits might have a 30 amps controller that requires either stronger batteries, or larger ones to deliver 30 amps reliably. Typical 36v kits have 20 amps controllers.

Well I'm still shopping for kits. I would like to be able to travel 25mph on flat surface, unassisted. Range is not critical. I wouldn't mind taking a hit for a significant decrease in cost. But 15 miles would be awesome. And although I'd like to be able to hit 25mph without pedal assist, I still plan on pedaling some throughout the ride, so not a true 15 miles. I weigh 220 pounds and expect to carry 10-15 pounds with me while riding.

Thanks

sun-thing28 guy has complete kits too. motor, controller, and battery. should be the same as the others.

BMS Battery has the best value batteries.
Lowest price and since they are probably the largest Ebike parts vendor on the planet, their stock rotates fast, assuring a fresh pack. For the battery alone, shipping is around $100 to the States.

Would this 11.6AH battery get me far? https://bmsbattery.com/ebike-battery/684-48v116ah-bottle-09-panasonic-battery-charger-battery.html

Remember to cheap of a no name ebay battery is a dead battery.
Match a battery to your controller. What kit are you getting ?

 

[beastcoast]

Can any of these batteries be made to work with another kit? http://www.ebikesofne.com/Electric-Bike-Battery-s/1929.htm

More than I wanted to spend but the store is actually 25 minutes from where I live. So perhaps I can pick up the battery in person rather than wait 6 weeks for shipping. And the quality is higher.

 

[dnmun]

no, the quality will not be higher. the pouch packs are all essentially the same chemistry. manufactured in the billions. the sun-thing pack i posted is made just like ping does, everybody copies him. but he is the cheapest source and the lifepo4 will last longer than the li ion. but you need to put your pack into compression. they cannot do it for the money they sell this stuff for.

Wbikesofine is high for what you get.But does it come with the 2yr factory battery warranty ? I guess not with a no name kit.

 

[TotalConfusion]

I know nothing of this Company but if you take a look at their batteries they are not too bad, They use Samsung & Panasonic but price may be a little high but for me its cheap and im considering buying either the 25 Amp 14s pack or their 18.5 pack.

Would love to know who this seller is as im thinking they are the guys in Croatia that cell the Cro motor but not sure.

Ok, assuming you kept the speed of a 48v kit down to 20-25 mph, you'd for sure get your 15 miles distance from a 48v 10 ah.

You'd need 48v 15 ah to let er rip full throttle the whole ride, (27-30 mph) and leave some reserve in the battery. Ideally you don't ride a battery to the very end every ride.

Which vendor is the best value is very hard to pin down. Cali bike has a nice price, but EM3ev has a reputation for quality packs. Value is a very subjective judgement that also includes cost, distance to the vendor if you should need customer service, how much you put value on a warranty, etc.

I have a very sturdy, but expensive allcell battery, No fuss to use it, unlike RC drone batteries. But it's discharge rate is a bit low, lots of sag using it, and not even using a 30 amps controller. It would be a great battery, if I had bought the larger one, a 20 ah. But 13 ah sags under a 20 amps load.

To sum it up, high value for a vendor in the USA, high value for a 2 year warranty, high value for less dangerous than lithium cobalt. not so great value for the cells being a bit weaker than I'd hoped. So value is a trade off of many things, and what you prize most won't be what I prize most.

Maybe I'm just spoiled by riding with RC batteries, but I wanted a battery less likely to burn the house or garage down.

Hi,

Are these prices for real and did you ever order from them ?

Thanks
