I'm logging the amps I get back in there and the time it took so I'll let you know the result, its rising in a balanced fashion and the volts are climbing slow so it looks promising, but the pack was assembled in 2009/08 and looks to have had moderate use in a hilly area so if I get 80% they have done well and will be perfect for their new job.flat tire wrote:Interested to see what the capacity is like on that discharged pack. As you probably know lipos are way better though. So little voltage sag.
Yeah that battery fits inside the downtube along with the a2b relays and all the main connectors, the shock has 3.1cm travel not sure what that equates to at the rear wheel yet, keeping the cargo area clear for storage would be nice rather than use it all for lipo and electonics, Ideally I need to get my hands on the b battery case and then fill that with 18s 10ah of lipo too so I can have 18s 20ah for a decent amount of poke and range while keeping the storage area free.ElectricGod wrote:The frame welds look good...all TIG welds. That battery pack was inside the main frame tube? I don't know how much the swing arms move, but make a new battery pack that fits under the cargo rack. Then you still have the top of the rack for carrying stuff.
When I first saw the a2b metro on the Web many moon ago I thought it looked a nifty bit of kit well built but out of my league cost wise, Many moons later one pops up local spares or repairs that sold for a decent price. After i was through mangling the hub motor I decided to just go all out and give the frame what she was begging for not to be a high speed monster but to be tamed for top speeds around 50mph with decent power and braking while attempting to keep it light. Got my air shock in the post and sintered pads more bargain bin parts as this bike is on a budget ive been digging around to find all the bargains and so far I'm not doing to bad on the budget but its not cheap by a long shot early next week should see some serious progress when the hub arrives.macribs wrote:There is something cool about the A2B bikes. Don't know what it is, after all it is kind of a step thru. But with attitude.
