Had a Lupine Wilma 6 for three winters and the battery is a bit knackered. It used to do about 3-3.5 hours on full power but now it's less than an hour. The battery is a Li-ion battery and allegedly 6.8AhM but I think it's down to about 2Ah now (based on run-time and also the indicator on the microcharger). That means it only does about an hour on full or 90 mins or so on 60% which isn't long enough for my usual night riding.
Any ideas on refreshing Li-Ion batteries it or is it just gubbed and needs replaced?
If it's replacement, any ideas on new batteries? SJS Cycles have a 5Ah battery at an eye-watering £125 and 7.5Ah at £149 which seems like a lot of magic beans for a battery - any better ideas?
No way I could make my own but is there anyone out there who will knock up a battery to a spec for less than the Lupine one? Looks like quite a funky connector rather than the spades last time I got a new battery for lights. All ideas welcome...
