Hi all. For the prototype of the project I'm working on we need a
compact 24V battery. Ultimately we will likely use an electric bike
battery, but to save costs on the proto I'd like to use a compact
sealed lead acid battery. The 12V 7AH battery that is commonly used as
backups in alarm systems seems to be a good size.

I need a bit of advice on the charging though.

1. Can I connect two batteries in series to get 24V for the operation
of the device, then use a 24V charger? Or will I have to disconnect
them and charge them separately?

2. If I understand this correctly, I should be charging these guys at
somewhere between 700mA to 2A. Is that correct?

3. If 24V charging is ok, what about this charger:

or would I want to go with something with a higher current like this:

?

Thanks!
