Just landed new ZEROFLEX PS-120A Battery chargers. These beasts have variable voltage (12V - 15V) and current (10A - 120A) so you can either trickle charge a battery back to health or slap 120A @ 15V to fast charge a big bank. If you have spare car audio laying around build yourself your ultimate home system powered by the PS-120A. Also note it’s 110v-220v auto switching so good for America Samoa as well 😉
RRP $599.

Note: these are also strapable so you can run 2 and get a clean 240a of power. Perfect if your planning on building a home audio system using car amplifiers.
