Hi,
Sorry to bother you (I feel like a first day schoolboy walking into a sixth form classroom).
I recently bought (dont laugh please) a 250 watt hub conversion kit with a 24volt 6.8Ahr Li-ion battery pack for my Mountain-bike, more like a gentle incline-bike really !
Performance is sad..... no, tearful is more appropriate, especially having spent hours watching Knoxie zooming around his home town at speeds of up to 27 mph. Mind you, I do leave OAPs in their invalid carriages behind, just about.
Anyway, my query. I often take the bike away at weekends to places where I am unable to recharge the battery (sad caravanner as well).
I was thinking of buying a second battery pack (SLAs) cos I cant afford the Li-ons. I know nothing about electronics and having been slightly conned once about the supposed performance and range of my conversion kit, thought I'd ask you guys for some advice (not "just sell the kit" please)
There is a battery company close to my home (Power-Sonic) in Wickford, Essex who advertise two different 12 volt packs at under £20 each. I was hoping that of them (X2) would be suitable as a back up supply should the Li-ons run out and be unable to be recharged.
Both the replacement options are about 4 kilos each and should not be a problem as I only weigh 10 stone and the rear carrier is quite strong.
I completely baffled by the tech spec and wondered whether one of your members could take a look at the specs and say whether you think one is better than the other for my purposes. One is listed as 12Ahr and the other is 14Ahr.
I will now try and link the spec pages I saved - if they dont appear (cos I'm useless with computers too) the website is http://www.power-sonic.co.uk and the batteries/specs are listed in their dropdown boxes marked Power Sonic and 10 year life batteries.
Thanks very much for a useful forum. (wish I understood half of it !!)
