My situation is that I am trying to install LiFePo4
as house batteries
but im doing it from the other side of the world from my boat
( Im in Australia
and the boat
is in France). Ive looked at the DIY
approaches on the other posts but its just a bridge too far with not being there myself for a few months yet.
set up -
Generation - 400w solar
, 2 x 80 amp hitachi alts off the engines (its a cat). Shorepower through a mastervolt combi inverter charger
- 2 x dead 270 amp AGMs for house and 2 lead acid starter batts
Proposed set up -
1. replace dead 540 amps of AGM
with a single
from Smart battery
(link - 12v 300ah lithium ion battery
(or a similar "drop in replacement" battery
if anyone has other suggestions?)
It includes the BMS (battery management) so it makes the remote
install alot easier basically which makes my French sparky alot happier
2. No alt regulator
yet so was looking at the Sterling alternator charger Sterling Power Products: Alternator to Battery Charger
as its again a simple install, has a setting for LifePo4 batts (14.6 v charge and 14.4 float) and can charge the starter batts and the house seperately. (if i go with a normal alt regulator
then ill probably need to charge the starter batt off the house which im not that keen on for redundancy)
So what do people think of this proposed set up? any issues with the sterling alt charger especially when used with LiFePo4?
Anyone with experience of the smart battery units?
I know itll cost a little more but its not over the top compared to the quoted AGMs and i need an alt regulator solution anyway so thats not really an added cost to me. In fact the sterling alt charge can manage 2 alts so its actually a bit cheaper.
