    Charging rates vs cycle life

    Yeah, the resistor in series is not the correct solution for reason's already touched upon. >ELG-150-54A This looks quite interesting: adjustable current (up to 1.4-2.8 Amps) and voltage (49 ~ 58V), relatively low cost, fanless, water resistant, well known manufacturer. Though, it is an LED...

Unfortunately they are backordered, so I'm thinking of getting their other reasonable priced charger...
