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.

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.

Honk which high drain cell do you recommend.

If I had and empty battery box I would take it to Bolivia as they have a big supply of lithium can you smoke lithium AR does lithium just smoke AKA fire. Yes I don't think it's the lithium I kind of bet on Cobalt and magnesium is the best fire starters.

What I meant by the 16 s 2p pack if you can fit that many cells ( 32 ) in your battery box you can parallel the two packs for more ah.

How much more room do you have in your battery box ? And how many cells do you have in parallel now ? Or how many ah is it. As I would run a Samsung 25r cell 16s 2p or 3p ? Need to over match capacity a little as the cells are 20amp or you need to match the capacity or more is batter for the little ...
