Should I stock up on 12v 4ah batteries on the upcoming sale?
I'm new to this battery tool thing and it is easy to overspend.
I just used my 12v angle grinder - very impressed how handy was that little beast. Had to cut through a small thing and it saved me a lot of time (I'd have to drag myself through corded logistics to hook up my other grinder otherwise). The 2ah battery from fully charged seem to have depleted rapidly as the lights flashed yellow after cutting few metal pipes.
Kaufland is planning a -50% sale of 12v 4ah batteries and I planned to grab one with the discounted mini saw.
However, after this cutting I wonder - should I buy more? I've got 3x 2ah 12v batteries already. Is +1x4ah sufficient or should I take two at least?
I know, seems like a stupid question, but I'm also saving up for Makita RT0700CX2J and I'm trying to be smart with money and I dunno if such sales happen often.
