Have you not thought about trying the railway or finding a preservation the see if they have any spare coach batterys for sale.

Coach batteries are a little light generaly, normaly around the 220Ah mark and not good at delivering high current.

The current is probably not as high as you think (any KW ratings anywhere for the motor?) as otherwise they would be quad terminals to handle the thrutch (ala Loco start batteries and when some people fit standard commercial ones to save a few quid, they blow the terminals off!)

I found a Battery plate with the truck, it has no signs of if it was the original as it was floating around the pedal area when purchased, Also the company I bought it off were a research and development company in battery technology, don't think the exist now so the potential is the plate does not match the truck 

But this is what it says;

Varta industrial batteries ltd
Volts 48 - So correct so far..
Capacity 424   (C5) written next to it
Cell type 8PEB 424
Weight - Not etched into plate
Serial no. BH00947
Date - 7 / 87 ! so probably the original plate before a previous battery change?

There's everything you wanted to know (and probably more) about a Lansing Bagnall truck here:

OK, it's a smaller model and 24V but has details of the current it draws. By comparing the lifting capacity, physical sizes of the motors, etc. you should be able to arrive at a ballpark level of current draw, remembering that with a 48V supply you'll have half the current for a comparable power rating.

Thanks for the link, still need to find something suitable though, otherwise it's going to be an angle grinder a days work and a few trips to metal merchants!

Had a check in the usual places yesterday and we have nothing.

The only thing close was a large stash of 110Ah NiCad (so 1.2V cells) from the APT and some loco start batteries which were goosed (and WAY to big plus not deep cycle so no good)

Never mind, thanks for looking

My mate suggests contacting Les Barns at Barns Battery Services.

He said that size should be widely available and the above contact supplied a set of much rarer batteries for £400. Location in Essex might not be ideal, though.

Thank you for this, I rang and spoke to Simon who offered me 4 cells that I need for a good price just got to meet half way as Derby to Essex is 3 hours!
He was surprised no one had got any, but I have tried for months now ringing round with no joy, this is the first person who made sense and knew exactly what I needed

Excellent! Glad it appears to have helped.
