Lithium upgrade - last call

[Aloki / Oyster Bay NY]

Unfortunately, interest in the lithium upgrade for Nonsuch start and house systems is not generating enough involvement. If we don’t get a 25 guest minimum it’s not feasible to run the event. We’ve had an about 12-15 members indicate an interest thus far. Please sound off  if you’re interested as if we don’t have the numbers by mid November, the event will be cancelled. It’s a free event. 

But to recap , (this is based on an upgrade I’m doing on Aloki over this winter)

Currently, Aloki has the following in place (batteries are now 8 yrs old and not holding charge as they once did)

Start  - one 105 Ahrs AGM firefly battery 

House - three 105 Ahrs AGM firefly batteries. Wired such as to “provide” a 315 Ahrs bank

The upgrade ,

Start battery - still a winner and staying (still an AGM battery )

House - replacing batteries in place with two 200Ahr LiPho Victron batteries. 

With the addition of a dc/dc charger the lithium batteries will be charged via the start battery . The battery charger remains and will only charge the start battery. The primary battery ‘selector’ switch will be replace with an ‘on/off’ switch. 

The Pro’s 

Increased house bank that charges in 1/3 the time the AGM batteries did. More useable amp hours as lithium can be brought down substantially more than Lead Acid Batteries. Better monitoring systems for state of charge. Less battery weight , three AGMs weigh 230# and two LiPho  weigh 84# with 100 Ahrs more than the three AGM’s. Longer battery life span.  There are more advantages and safeguards but you get the idea. That’s the point of the event. 

Anyway, ball is in your court. If you all have other ideas for workshops, please share your thoughts, best Gary
