I know they hold 70 cells as i have a 52v5p one. With GA cells a 36v 7p would be 24.5ah .just cant see a uk source.seems dozens of chinese sellers make up 24.5ah shark packs in 36v with GA cells ,so whys no one here selling them? dont really want to buy a battery from china ,plus all the postage duty etc.i dont mind getting via a EU country tho,as i did once from a chinese seller.it arrived in a week costing £9 postage. thanks anyone if u can help.

he seems a popular source for batteries,i see him mentioned often in threads. the chinese made 24.5ah batteries of GA cells ive seen are half the price usually of UK equivalent.Do u think if shipped from europe a safe bet.ive had no issues with one shipped via germany in the past,LG cells.no import taxes etc either just £9 p&p.not half the price tho mind,but cheaper.

You can get them shipped from China or Europe no problem, but what happens after a couple of weeks if the bms goes down or there`s a couple of cells go faulty?
Buy local if you can.

Jimmy uses copper for bus interconnectors, each cell will have good current flow /share and a series connection on each cell.
China made cell packs are hit & miss with the interconnectors and usually skimp on the series connections, often only the first and last cell in a parallel string will have the series connection. Though some OEM batteries like the 14s one Woosh showed us a few months back and are improving with design/layout.

Yes local for ease of warranty. They are often chinese made still tho.The 52v 30Q battery i bought from electron cycles for example is a seriously good battery made for them by a chinese company.EC specialize in high performance and hot rod bikes. they dont compromise on quality and have chosen their supplier well they say.wasnt cheap mind. the pswpower LG cells one i got via germany is still giving sterling service a year an a half later too.

its hard to know what chinese sellers products u can trust isnt it.there must be good and poor ones.it was sellers on aliexpress,alibaba,dhgate etc i was looking at .seemed the only place to find 36v 7p batteries made with panasonic GA cells for the max 24.5AH in a shark pack.

im not sure i like having the frame and rack 2 batt set up (30.4ah total )on my bbs01.seemed good idea at the time but i dont like having a rack.wish i had just bought a max capacity shark years ago. the shark ive got is a 6p 29E cell 17.4ah i hate triangle batteries.
