Hi Greg,
Thanks for your thoughts. The inbuilt charger on the Aixam only looks at the terminal voltage of each of the 12, 12V batteries, not at individual cells so a new charger looks required. Considering the extra cost of Lithium over Lead and a new charger weighed against my maximum daily mileage I don't think it stacks up to swop to Lithium so I think I will do a straight replacement of my ABM 6-DM-76's.
Do you have any suggestions of a UK supplier of these or similar 73AH batteries?
Thanks. John

Secbattery.com may have a suitable replacement. I used them quite a few years ago and found them help.

Hello,
I have found Leoch Deep Cycle Battery 12v 75Ah - LPC12-75 which is a virtual direct replacement for the existing batteries.
I got 5 from a mobility scooter company on ebay for a very good price and 7 from the Battery Company at a reasonable price.
In total, the average cost including VAT and delivery for each battery was £102.80 which is a very good price !!. I have installed the batteries and they work fine. The external dimensions are very slightly different which meant I had to shuffle the batteries slightly so the interconnection leads would reach but apart from that I am very pleased. I hope these last another 5 years like the origional ones did !!

Re: Expert battery advice needed - Aixam Mega City
So, someone please correct me if I am wrong, but Carl's photo of the AMC's battery layout suggests a '3P 4S' (3 parallel, 4 series) layout which equates to a nominal pack spec of 48V, ~200Ah weighing ~250kg?
If so, seems to me the ideal replacement solution would be 4 x Valence U27-12XP on their sides weighing, together, a 'mere' 80kg with about 30% more capacity (allowing for Mr Peukert)... only they cost £2k EACH!... unless, of course, you could find some decent second hand ones...
I would guess as well as a small range improvement, the acceleration would be transformed, too.
Does anyone have any technical documentation and/or diagnostic tools/software/hardware for these vehicles? Or any knowledge thereof?
I have a possible scheme for a few of these cars in mind but any sort of official servicing would be impossible - it would all have to be DIY...
