this is why I'm skeptical about the BP-500 if you use a small amp
?
if you use an amp like the PA-500
it's ideal to use solar --> controller/hub --> battery --> ( multiple devices)
?
the Buddipole power mini 2 supports this if you can't get the DIY599 BAT-500
?
the BAT-500 is great but if solar can't keep up w demands, you'll need another battery as a backup anyway
?
IIRC the BAT-500 is 4.x Ah which good if you operate in a sunny environment?
