OK. So I have two C5's, both converted to run off leisure batteries. One is a Yuasa 75 AHM battery bought from Fezza which is great. The second is a 85 AHM Diamond Leisure battery bought brand new from eBay.
Even when fully charged the pods don't stay on full for very long. The Diamond Leisure battery still shows as 75% charged on my battery charger, yet is hardly powering the C5 at all, and the pod very quickly starts beeping and shutting down the power.
Why is it that even though 75% charged it stops chucking out enough to power the C5? I'd have thought that there should be enough juice to keep it running efficiently?
