Only talking about imr.. Got an ipv4 and I've had several regulated devices before so got plenty of 30-35 amp batteries, but was wondering is it alright to use 40 amp continuous batteries in a chipped device, like I've used 20a before but I could tell I was getting less power then 30a even with it set at same wattage. More just worried about frying a chip or something but from what I've read its more of a problem with low amp batteries then higher amp but thought I would come on and get some schooling before slapping them in new device. Also because most devices say to use 30a batteries only.. Thanks for input.
