Inverter power rating?
<< < (4/4)
NiHaoMike:
Have you looked at 12V input R/C chargers? Limit the charge voltage to 4.1V/cell and the charge current to 1C or less to increase battery life.
iXod:
The battery is not balance-friendly (externally), but made specifically for these power tools and its proprietary charger that communicates with the battery’s on-board monitor.

Not really up for the challenge of reverse-engineering the factory charger’s communication protocol, etc.

Cheers.
iXod:
The rapid charger is now drawing 1.8 A on 120 VAC while charging one of the (almost empty) batteries.

What current might this translate to at the 12 VDC input to an inverter?

Any guestimates?

Cheers.
iXod:
Thanks for the well-calculated guestimate.  ;D

I'll take some measurements when I have the inverter in-hand.

Cheers.
