They have 4 wheels and are used for transportation aswell (with trailers), they are operated by a handle similar to a hover mower. Would be grateful to know a manufacturer.

I would like to charge a pair of 3.7V, 1500mAh Li-ion cells but I do not have a charger for them. I would like to use a normal power supply to chrage them I just dont know what voltage and current i should put across and through the cells and for how long I charge them. Also I am not even sure if they are charged (I assume not because they are brand new) is there an easy way to check this? Failing an answer does anyone know what charger I could buy to do the job? Thanks

OBJECTIVE:
1)circiut to count number of black strips(on a white back ground)
# numbering can be in binary ie (range of 0-15) with 4 LEDs each reprsenting 0-1
2)circuit to give a signal (lighting of LED) if RED colour strips are countered (on a white back ground)

NOTE:
1)must differntiaite between red ,black,white.
2)lighting ,exact intensity of red is not known so the Answerer should explain the logic clearly so that adjustments might be possible.
3)exact specifications of electronics used will be added advantage
4)circuit diagram should be mailed to ramthegreatcv@yahoo.com
5)the answer if elaborate will be greatly appreciated since the user is a novice
