Hi people,
I have plans to add a seperate 12v battery to my wheelchair which will run the lighting and for something special I was thinking of adding a solar panel to help keep the battery in good condition as I believe if a battery gets too flat it dies.

Would one of THESE be any good to add abit of charge to one of THESE?

Obviously the lights would only be on for a coupleof hours at night so would have all day to get some charge in. The alarmwill still be linked to the original batteries which are locked in the box under the seat so noone can tamper with it

If you have the space for that 12W panel it could buy you a few hours. The battery's about right too. You're right about killing batteries as well - allowing that sort of battery to drop below 11Volts or so will cause it's internal resistance to rise and it won't take much charge any more.

If you manage everything carefully (i.e. switch off if you see it going flat) and don't overcharge the battery (i.e. leave it all connected, in the blazing sun for days on end without discharging it) you'll be OK - otherwise you will need a solar charge regulator that also has a low-voltage disconect system to do it all automatically.

Something like thiswould do.

I think the solar charge regulator would be a good idea, just in case :) I know i would get it.
