各位師父, A200的專用電是7.4V的, 但火牛插頭是 DC IN 6V的。
我DIY了一個4 x AA電 (4x 1.5V=6V)的電箱, 接上火牛插頭, 但開不到機。
有冇邊位師父可以幫幫手??
謝謝!

I am not a A200 expert
but I think the problem is :-

If you use ordinary AA dry battery
the voltage will be <6V if the DC draw current
from the Batt. Dry cell cannot give enough current(A)
for DC

If you use rechargeable AA cell
4 cell only gives you 1.2x4=4.8V
you have to connect at least 5cells
that is 6V.But the cell will drop current
when the DC is on.


Anyway if A200 uses 7.4V
that is - 2 Li batteries
you have to supply enough current to
replace Lithium cells

Another way is to connect 6 rechargeable cells
that is 7.2V.

But the question is - it is harder to find a 6 cell
battery case - I had found some but the results
are not good

If you want to replace 2 Li cells
the battery must have enough current -
AA cells seems not a good one
D or C cells are big and expensive

So I suggest you may try to use back Li cells -
if you know how to buy, connect and charge It

But all at your own risk !
as Li cells are quite dangerous if you can't
charge and drain it properly !

Try to find "lead-acid" battery, Becasue the voltage is 6v for each.
You can easy find in apliu street (sham shui po).
