January 24, 200818 yr Hi I'm about to replace the three 12v 7A batteries in my battery pack. Looking across the internet for replacements, I found the following site: Batterymasters.co.uk - Home They supply 4 variants: Power-Sonic PS-1270 - £7.99 Ultramax gel - £6.99 Yuasa SLA NP7-12 - £9.57 Yuasa SLA NP7-12F - £11.36 Which ones would be suitable for an electric bike? The Ultramax seem to be a bargain buy, but working on the basis that you get as much as you pay for, should I focus on the Yuasa's? Many thanks.
January 24, 200818 yr Hi, I've been doing a lot of reasearch on these too. Just the fact that Yuasa seem to be by far the most common battery stocked by most retailers says a lot. I would be willing to pay the extra.
January 24, 200818 yr Author Thanks gkilner. Well after a two hour trawl of the net - I keep coming up with these - Deep Cycle AGM batteries: VERTECI - Electric Bicycles, Scooters And Motorcycles The one applicable to me is the 12V 9A "DK1290C SLA - AGM - Deep Cycle" battery, since it has the same dimensions as the batteries I am replacing. Considerably greater cost at £33.96 (inc vat and delivery). But is this the type of lead acid battery type I should be thinking about (Deep Cycle AGM)?
January 24, 200818 yr A battery that has good deep-discharge characteristics would sound like the one to go for. Although that price does seem very high. Yuasa do a special model for bikes/golf biggies/elect wheel chairs the NPC range, unfortunetly, they don't list your size of battery as being available. The stanadard NP range is a general purpose battery but is supposed to be designed for cyclic deep discharge also. YUASA BATTERIES Bikes and Batterys sell a battery for the size you require, Sealed Lead Acid Battery This company deals with Powabykes, the 12v 15a version for my bike is about £26, so your 7a should be quite a bit cheaper. The batteries are made by PBQ which don't seem very common but, this company also sells these batteries on ebay and gets some good feedback. Could be worth a try.
January 24, 200818 yr Author Thanks gkilner. Finally went for an AGM battery (Powerfit AGM12V 7A), purchased from RS-components.com. https://uk.rs-online.com The price I paid was #21.50 exvat per unit. (Sorry no pound sign on this linux computer - yet!). Many thanks.
