bought one of these from flee-bay. I got a battery top given off a mush when i bought a pod from him, so as it cost me nothing I chopped and cropped it to fit. Charged about 5 times and doing good. Only seem to be getting about 15 miles though :-\ . According to the C5 manual on a battery half this size I should be getting that anyway. Oh well, for what I paid it isnt bad. Marra

Never mind the manual i'm thinking 15miles is very good - would be interesting to know how it keeps performing over time -Thanks for that.

So 15 miles on 76 ah is good, I was looking at getting a 110 ah ;D ... pretty heavy though :( May get another one of these .... more miles then.

What's the weight of that Marra? Can you bung it on the scales for us?
-
The advert says.... "Weight approx 27.5 Kg" :-*

Mine showing 29.5 - 30 kg.

That is quite heavy, doubt you could run a 24v using two of those as I'd be worried about the chassis.
Not a problem though if you're sticking with 12v and carrying just the one battery.

You are right, If I go 24 then prob just buy a couple of car lead acid ones like recommended on earlier threads. This one seems to be good as its lighter than 2 x 36/38 ah ones that I have seen, but getting the same ah's.

The advertised weight for the battery is obviously prior to charging.It weighs significantly more when full of electricity!!!!.
-
Actually, my 45Ah car battery weighs only 12.5Kg.
-
They sound to be better then, what type are they ? Only thing with that I would have to buy another charger. suppose they cheap enough anyway.

Hi, I splashed out and bought a Ping battery off Ebay. Ping builds them to your spec and they are Lifepo4.
Battery spec
Lifepo4
12v
40 Ah
Weight 5kg!!!!
The Results?
Well I get about thirty miles from a charge and you really notice the 10kg weight saving. I Pulled the guts out of the Oldham battery and put the new one inside so it looks original and retains key.
These new Ping batteries really are superb.They cost £350, but will outlast the life of a lead acid more than eight times over. :)

£350 :o
-
That's exactly what I was thinking! :o :o :o :o :o
A bit like the printer being cheaper than the ink. In this case, you could get another C5 for £350!!
-
i was thinking more about doing 30 miles in a C5 :o, what 'numb bum' time that would be ;D

A superb effort mate, and very impressive.
I've always fancied a dabble with lithium based batteries but never had the spare cash to justify it.
It's good to see them actually being used, rather than just in theory :D Are they more fragile regards charging ?

A cluster of four of these Foxx 3.2v cells: http://cgi.ebay.it/Foxx-Power-LiFePo4-40a-Cell-/140350983908?pt=LH_DefaultDomain_0&hash=item20ad920ee4

I use a Marine semi traction battery 105 Amps, the specs say you can empty it to 80% of its load many of times, it is about 28 kilo and so big that I sometimes hit the back of my feet against it when I try to pedal :D
45 miles I already did once, no problemo. Still had 11.50 volts on the meter during the end of the ride, power on, that was about the same when I started. price about 100 pounds.
I'm going to swap it for a 80 amps version because it is about an inch shorter. And obviously shorter. ;)
There is a 55 amps version also that costs 55 pounds weights about 16 kilo.
Going to try that one for my second C5 that currently drives on a 80amps car battery. Car battery goes faster when its full but drops speed gradually. And they tell me that its bad to empty it more then 50%. Kills the battery.
