You want about twice the Amps you are drawing in my experience.

So 40 amps would be acceptable, its getting hard to find a UK battery and even when I do they are made up of PF cells even if I could go custom that would be a hell of a lot of space on the credit gone!

I remembered watching that dude from Ebikeschool.com on youtube with his affiliated aliexpress "best" sites/manufacturers to buy from, I re-watched it and found this on the "recommended" battery site...

Samsung - I assume F or E it does say 10 amp draw

The only 2900mah cell from Samsung is the poor/mediocre 29E, the 2900 PF is a far superior battery for amp draw and is a proper 10a cell though in reality it appears that 2700mah is more like it's true capacity. Still a very good cell for he price.

Goes to show whats in a name, even though its a "good" brand it may not be gold...

So if I can UK made is looking the best option being PF, and the fact I can actually confirm that via contact added with the English mans word n all...

So how does the Sanyo GA, Panasonic PF compare to the samsung PF because it looks like if I go UK its samsung PF and if I go China its the other sanyo GA or Panasonic PF if I can trust what they list, and from memory I think theres not much price difference from high end china and Samsung PF UK

o_OMe thinks your wires are crossed or misunderstood my post !!!

Samsung don't do a PF cell, PF is a Panasonic .
Samsung do a 29E cell a mediocre cell.
GA cell is Sanyo or Panasonic depending on which factory/country they come from, Sanyo own Panasonic. The GA cell is 3450mah 10a, PF is 2900mah 10a.

Yep your right - looking at too many websites at once - the PF was on the UK site and yes it was Panasonic I think I meant how does the GA compare with PF - Samsung E are off the cards they are in the chinese sold batteries labelled suitable for upwards of 30amp draw no more than 70, not going to trust that now! Samsung 30Q are not used and if I find there are the price would be way to much anyway.

Which leaves the UK panasonic PF (pricey)or another chinese battery more expensive labelled containing sanyo GA batteries....

PC are you looking at buying a battery or just cells ?
Just a battery, I find myself increasingly using my throttle and pedalling which even set to PAS 1 overrides the PAS 1 speed limit I set and puts me up to full speed at the moment 500w+ so if I do this on my new setup 48v 17amp I will be using frequent bursts of high wattage so I need the battery to be able to handle it... or change my riding style(unlikely) + I want it to last no point in spending a lot and it failing in 6 months!

The GA in price is very similar to the 30Q on Nkon so should not be much different in real term battery cost though we know battery mark up is a rip off.

PF and GA are both very good 10a rated cells, GA is obviously more expensive because of the extra mah, also LG MJ1 is another very good 10a cell.
My 48v 17a Yose uses a pair of 10s 5p PF packs/batteries in series with a 3s6p booster packs then both are used in parallel. On the 2 1/4 mile climb out of Ovingdean (Rottingdean south coast) to the Falmer Road north of Woodingdean the cells deal with load asked superbly even after 50- 60 miles of riding, then I jump on to the downs for some off road inclines.

Depends on the range and terrain to suit your needs, the GA has been said to be 12a capable though there is a crossover where the 30Q is a better cell but only for high amp draw of 7a per cell or more.
In 13s5p PF could be good for up to 60 miles dependant on all the variables,
GA I have no experience of but as it has 20% more mah then 75 miles or so could be it's range.
As we know fake cells come out of China so it is a gamble dealing direct unless it is a reputable source.

Amazing detail much appreciated...did you build your own batteries or get them custom made?

so it is a gamble dealing direct unless it is a reputable source.
I feel the same - the source of the Chinese batteries I linked were from that ebikeschool youtube channel "buying from China" run by a dude called Micah, he seems to know his stuff, that said the GA price is near that of the PF from the UK if they have the stock, the only downside is the UK battery is a "shark" case and looks massively heavy....

Long range is not really on my check list, I am just concentrating on reliability, high amp draw and quality, the range would be a bonus when the time comes to test it.

What about LG HE4 2500 20a 13s4p or 13s5p?

HE4 & HE2 are good, I use a HE2 build on the Swizzbee and is very good as up to 60 odd amps can be the load, though only 2500mah. For a 17a controller and if your not doing man miles the PF is a great cell.
I mainly build all my batteries now, still have 3 hard case batteries which I have bought. For a typical 10 or 13s battery build PF are 2.75 euros from Nkon.

If you have a battery case /old battery get Jimmy to recell with 30Q.

Have 2 cases one in excellent condition and one not so cosmetically, they are still in use and are my 2x 36v, they are dolphin cases, when I last looked in inside to remove a rattling nut there was only just enough room for the battery pack all shrink wrapped up. Do you think a 48v setup would fit?

10s4p (marked 10ah) & supposedly 10s5p(marked 14ah) but I have my doubts as the 4p is older by 3 months and they range out at about 30 miles on a good day.

I have found some one on ebay, a UK battery builder I have emailed them for suggestion(even though others have yet to respond) If I do find them to be of good standing I will pay via paypal and if anything goes pear shaped I am sort of protected.

Here's the bike i'll be placing the kit on. I bought it off ebay for £40 quid. It's an GT aggressor xc3 from around 2009. The pas fits very well. Although while I had it upside down the upper part of the fork's stem is pure rust. Is this unsafe to use? Thank you.

Possibly worth replacing IMO cheapest forks are around £50 upwards but do check the size - Plus I would suggest a torque arm if its a 350w motor unless of course you have one on the other side.

Here's the hub on my GT without grinding;

If you look at the first photo. Does the tab need to be where i've drawn a line please? Thank you.

Hi. Yes, the tab needs to be down in the droupout. I fitted a 36v version lately and had to grind approx 3 mm down into rear dropout (to give a total depth of about 16 mm) so that the the whole axle and torque washer tab was nice and secure in the dropout. This was no problem as the dropout was large and solid and had plenty of metal. I had to widen dropout very slightly also.
I can see a possible problem in your case as there is a moon crescent shape hole on the non drive side of dropout, so perhaps you will need a torque arm ( or two) instead.
