Using linear regulator with NiMh cells on winter time is quite frustrating, battery power dies very fast.
Is anyone tried LiFepo4 cells and build charger for them what will work with dynohub. Will LifePo4 cells work better?
Current system is simple, dynohub 7v.3w, full-bridge rectifier, 78xx(fixed 11 v) with 8x 1.2 v. NiMh rechargeable cells, headlight 3x 1w and taillight 2x?red they both have own led-driver cause they are different type. It's "trash_made", only leds and veroboard are from shop and all other things came from broken electronic (and yes I know that TV receivers, accubatteries, old capasitors etc. can cause Nuclear disaster and terrorist can steal them from my bike... :huh: ). So new system might be need fresh shop hardware but testing unit can still made from recycled trash.
Maybe switching power-supply and more effective leddrivers helps, any good ideas. System size or weight is not big issue cause I never take off bike panniers but lead-acid accu system makes bike unbalanced and that way it's too difficult to carry on third floor apartment.
If my enlish is not readable or I presented myself too vague, please, brace yourself with Courage and tell me, I will try my best to make clear what i tried to tell or ask.
