My A123 20ah pouch can put out 100amp. In real life and live long life . Can you fit the size ? Hold the weight.

Nice. If it ante rubbing it ain't racing !
Free test ride. Love it.

Sounds like 120 lbs of battery ?. Should take care of sag. If I wish one battery to be bigger it would be lifepo4 because of its flatter discharge curve.

There isn't much energy or capacity above 3.5v in lifepo4 or 84 volts. The 24s will charge higher but will drop to it flatter discharge curve . As li-on losses voltage faster in discharge. But together? Let us know how well it works over time real life as I see this as a good combo for marriage 20s ...

Get the book.

Learning the BBSO2. Yea I loved my muxus 28mm first day it melted. It took 4 weeks to melt muxus 3,000 5t. Two weeks to melt my edge 1,500. Keeping my new muxus 3,000 4t turbo running for 1 year. Its a learning process. I too think it's my batteries fault. Dam batteries.

There are many favors of 18650 some 1amp cells some 30a cells. At 30amps it won't have much capacity. Because 18650 is the size or capacity of energy that can fit in the cell. How many amps is your controller rated for.

Checked out your website you look like spinning magnets little brother. What's up with that ? Ceramic over didn't know we're having a spinning magnets look-alike contest.

It depends on the tire rim combo. The first 4in pedago fat bike had a hard time keeping the tire on the rim. The tire with the spider design was really bad. But pedago use the cheapest of cheap parts as the rule.

20s 18650 called 72volts 24s lifepo4 is called
72volts. You would need between 6 to 10 in parallel or as needed.

Sorry sounds like cheap no-name battery China use as is. Just use it in within its rated discharge. Long time ago ping medical battery you also rated it. Kill a 48v 20ah old Ping on a 40amp controller. 2,100 watts for a 1,200 watt pack. Ping has better packs now. You don't. You buy shoes at Payless ...

Get some kool stop dual color brake pads.

Take those old cells and put in the backyard BBQ. New cells only name brand cells. I bought 35 Makita tool packs or 350 Makitne cells the seller can only find 27 Packs. The next day he found the rest to fill my order. I open the top on one and fire shot out the top of one cell. Happen 5 times more. ...

A motor also makes heat when it luggs or Troggs. Its making heat in sand and going slow in thick mud. For the most part. This gets magnified when you over volt it or over amp the motor .Do you have a 350 watt geared motor ? Geared motor can hoer heat longer or quicker than a 28mm dd motor.

Now just ride normally and don't make every ride a test ride up the steepest Mountain or ride to the very bottom of the pack as the rule. Just learn it.

Remember when the debut the new Boeing plane and it's new battery caught fire I forgot why or what batteries they were using.

You can charge them with one or two meanwells and monitor. The quality of the cells should make ez to keep balance like 4.1v . Test ride. Picture of that ebike grin.
What's the finish measurements ?

Hoverboard fires ?5years ago I worked at a pedago dealer I looked at how cheap there packs were made I told him to get a fire box and put the batteries in there with a pipe to the outside.

Four threaded rods cover with clear tubing with alternating plastic and aluminum blocks I threaded the aluminum blocks for sense wires or bms . I did put Vaseline on parts

I want the size of the 18650 pack I like having two connections on my 20ah cell I want it to fit in my triangle. So 80volts 20ah @ 80 amps. Long life. Pouch is ok. Right now I have heavy 24s A123 20ah for 5yrs 1,390 cycles 23,000 miles still good. But needs the triangle and rear rack yes big and hea...

I'm having trouble making up my mine. I have a 24s of A123 20ah and is heavy. A 16s is doable because of there hagh amps. I want a 18650 Samsung 30q 20s 9p. But all those connections and series buss bar proplem at 90 amps ?. All other 15ah 20ah cells don't fit evan A123 20ah are to big and heavy..

What voltage are the cells now ? Are they the same voltage ? Only parallel and then drain cells if matched voltage. 180ah is a lot of energy.

Is the battery balance before you hookup the bms ?

How'd you pay for it ? Make a complaint have them send you another motor they may just have you keep the first motor that they sent you and just send another one. Squeaky wheel gets the grease.
