Hi, As my robot has evolved I've progressively added a few extra components to the system, although they're quite power hungry (200-300mA). My current battery is a 12v 1.2Ah Yuasa sealed lead acid type (9.5cm x 4.5cm x 5cm).
Without going to the absolute extreme, although I am prepared to pay a fair amount more that I did for the original, what possibilities are there for a more powerful supply - Sill at 12v and as closer size as possible to my current battery.
(Max. current drain with all systems on and motors stalled is around
1.5A)Thanks
Mark
