Surreal. I help the guy we want to succeed by pointing out a serious fundamental error in his public material, and i get this nonsense.

May i suggest folks actually read posts, and think on context and intent before wasting our time with aggressive drivel, certainly not the first time for hillhater.

I simply told the Westan guy (since he had posted here anyway) he had a key spelling mistake he inarguably (one would think :( ) ought correct.

i see that you are using an anderson plug on them... i've started using xt60 and xt80 which are easy to solder with low temp solder and they dont oxidize like anderson plugs do, adn the contact surface is more reliable. xt80 last perhaps 10 times longer at as far as i can see.

I've tried 5 times to contact westart and at the top of the page is printed (This page is not supported) and won't accept the conformation code. Given my skype contact. We can just wait.

Mrs Kelly 's Skype name is at the first page of the forum. She is very helpful.

You are right 100% the reason I use this one is because I have an old battery with the same connector so it's easier to swap batteries. My favourite connector is the XT150. How many amps in real life the XT60 can handle?

This is adaptto 's statistics screen.
14s 1P 10AH graphene cells from WESTART.
Peak 5.7KW power, maximum speed about 70km/h with magic pie 4.
Very impressive for such a small battery.

Thanks for the link & info. Am interested pouch cells that improve on the price/performance ratio over A123.

I wouldn't buy lithium batteries with aluminum sheets , lithium complexes with aluminum forming an alloy some batteries use the alloying method as a storage mechanism but these batteries alloy irreversibly I suppose so when the active layer gets swollen with time the lithium will get trapped in the aluminum sheet and you will loose functionality. The alloying batteries get 100-200 cycles at max.

Isn't this method widely used with no problems. It looks like same method as A123 20ah pouches that are almost 10 year old no problems.

Yes many lithium batteries are build this way but it depends on the active material.

Ok Thinking two 10s 20ah modules. Size for two end to end is 110m wide x 410m long and 140m tall with tabs and connections and will fit my triangle. 110 m between the cranks or 4 1/2 in. Is this to wide ? 84 volt full charge and 120 amps ? 9500 watts. 20s shipped 615.00 usd. Thinking my thinking needs help. Help.

Plus how fire resistant are the cells are they more like lipo or more like A123 ? Need to buy before the Trump Chinese tariff. I don't know why people aren't excited about the cells are they just too big and heavy long cycle life High amp displacement.

Hmmmm. Slightly lighter than a 20Ah A123 (about 10%), I guess the higher nominal V means about 10% more capacity too. Much cheaper. If they hold up as advertised I'm actually a bit interested. They look like I could package them into the triangle of my touring bike in 2 stacks of 7, unlike the A123s which don't quite make it. Of course they're not going to be as safe or last as many cycles as the A123s.

Would be cool if someone tested them.

Thank you. I like big capacity cells EZ to monitor and diagnosed. Plus manybe 18s at 120amps. Thinner.

Ok money in hand and it's getting hot to hold. I text Westart 4 days ago ? Me thinking China still in holiday mode
So how good are these cells ? Very little feedback from you guys ? Going for 20s 84v top charge. As two 10s for a long pack to fit the triangle. It will be between the cranks at 4 1/4 or 120mm wide. I hope this wouldn't be to wide ?

Are you getting the Graphene ones ? ( interesting that Westart calls them Grephene , and H.K. list theirs as Graphene )

I , and I am sure others as well , am very interested in how they come packed , how you put the tabs together ( Bolts, aluminium spacers , other method ? )
Your home made box to mount them, total weight of the pack etc. with pictures .
How you attach the Balance Wires , you are going to use a hobby balance charger ... right ?

That's just because they didn't spell it right in whatever their first document was, and it's propagated to all their others like that by now. Happens a lot in translated stuff, especially technical documents and names and such.

Ok received email from westart they only have 10 ah cells at the moment. So I can guess a 20s 10ah pack could put out 100amps @ 80volts for my muxus 3,000 and 1 first gen powervolocity sinewave controller. Good man.http://powervelocity.com
