Hi all.
I'm looking for a quality battery for my 500w Tsdz2 motor. I purchased the bike pre built by its previous owner from new. It came with supposedly a 48v 1000w Chinese triangle battery, which he was quick to say was more like 650w. The Maxcail battery is now failing to fully charge @ 52.6v. and will shut off around 45v. I'm looking at Samsung 25r 10ah, Samsung 30e 17ah or maybe something in between. Obviously the higher ah would last better as I also run f/r lights very occasionally but are heavier. The 25r are lighter and cheaper but are they good value? It's hilly here in Cornwall but my ride to work is only a couple of miles. It would be great to have a battery for longer runs if possible though, 20 miles? I mainly use settings 1 and 2 but do have some steep hills that need 3 or 4. Any advice would be gratefully accepted.
