i never understand why they put 70A breakers on chairs with 100A controllers etc, - dosnt make sense to me but still they work fine makes me thing how long or often are we using up 100A or 120A on our chairs -

if you used 16 of those 90ah Cells at 2C rated - then it a bit more than borderline min. for our chairs at 360A
if this is correct - you can use a 2C cell if 90ah and using 16 of them ? this would be OK ?
Now of course if a 90ah Cell at 3C is used - would be much better at 270A for 90ah Cell at 3C
and of course you would use 16 Cells giving 180ah of battery at 540A discharge rate ? is that correct ?
i am curious to know because i do find many 90ah Cells but are 2C rated - which is still ok if the above figures and my understanding is correct .
i founds some 90ah Cells at 5C - which would be great but too tall at 280mm -

i really wont know anyway - i will make it - and use as an ADD ON and thats it - i am sure they will give me some more range and last many years - this chair wont be used as much -
i may have to make connectors with wires - dont think i am getting any - i asked for them but they said they will try - so means they dont have them and may not get -

Sure no problem - i was thinking of that also - take it slow and try to make it simple steps - with pictures - will try to make it simple to understand and easy to follow with pictures step by step -
if you used this 60ah Cell for the whole chair - you would have 120Ah pack - 16 of them - the seller has been helpful and making an effort to make me the connectors - hopefully they work out - i should expect this order sometime in July if all goes well - free shipping takes up to 36 days - maybe sooner - they havnt shipped yet

Today completed assembly of 8 nos. 120Ah cells into a pack. I followed snaker's mode of "Rice pack",though not so perfect. Used 1mm silicone sheet (cheap and quality in India)and glass fiber tape for cricket bats.

I would like BM to give a preset for charging the set.
