that alarm would work, there is maybe the same but less cost ones.
I think i would choose a charger with a display so you can see what's happening with the battery rather than one with leds. For batteries this size you don't need a powerful charger.
Battery i'd choose the small capacity nano techs. 2200mah rather than the venoms. google N2200.2S.25.
I might have to consider that battery or one like it. Cant beat the price though thats for sure. I paid more for my Mini-T battery.
