Sterling Power BB124870 Battery to Battery charger (12V/70A--->48V/17A)
One of the few DC-DC chargers on the market that correctly and quickly recharges 48V lithium batteries
This DC-DC draws up to 70A from the 12V alternator, recharging the 48V lithium batteries with a current of 17A.
We recommend using this DC-DC with an alternator of at least 120A.
ATTENTION: LITIO.STORE only sells the new Green Label models, with improved technical features!
Doesn't this drain the engine battery?
No, because the Battery to Battery charger starts up and begins charging the house batteries only when it detects that the starter battery is being charged, i.e. when the alternator is producing current, so in practice it draws current not from the engine battery, but from the alternator itself.
As soon as the engine is switched off, the alternator stops producing power, so within a few seconds the engine battery's voltage drops below 13 Volt. At this point the Battery to Battery charger switches off automatically.
