[QUOTE="oexing, post: 174761, member: 1493"] I believe I got two bikes with 6 V and these LiFePo4 batteries , sorry , my brain is no more as sharp as was in younger years. I had NiMh types for some time in some but not worth the money. They do 1.2 V per cell so you need quite a few for 6 or 12 V systems. A few weeks ago I got a Li-Ion pack from Aliexpress, was a mistake as I did not fully read the description. The block got a total 14.8 V from the LiIon cells so the Earles BMW with 280 W would not be able to fully charge it. So next week I hopefully get 4 of these LiFePo4 cells to go into the R 69S . Yes, the Li-Ion types have higher voltage at 3.7 V BUT these are the explosive kind like in laptops or smartphones. You can certainly get readymade LiFePo4 packs with all sorts of wattage and voltage but I would not want to pay that money. Enter a search for "LiFePo4" at Ebay or Aliexpress for looking at a choice of cells or packs. So far I had no troubles from these batteries even with ancient regulators on 6 V Bosch dynamos, no electronic balancers like for Li-Ion packs recommended. You cannot go wrong much at that kind of money when you solder up the cells for going into the old emptied case. Vic [/QUOTE]
