The L16's outperform the 105s by far but I suspect total cost will be higher too.

Re: Trojan T-105 6v Batteries

Not sure what the current prices are but we could get Trojan T105's in the $90 to $95 last summer in western Florida from Affordable Carts...

Affordable Carts - Batteries

and...

Batteries-To-Go in Englewood, FL

and...

from the guy who came to the boat yard to service their golf carts that they use for about anything. When we return we will go with him as he will help me get the batteries down out of the boat (on stands) and the new ones in.

All three of those places also carry the Powertron for about $20 less each. They are 210 AH vs. the Trojan 225. I'm considering those as we got along with 180 watts of solar on our other boat with two 12 volt RV batteries and on this boat have four 6 volt batteries and 480 watts of solar and actually less of a refrigeration load with the better insulated fridge/freezer vs. the portable fridge in the other boat.

If you are going down past Florida maybe the prices are better there with all of the golfers??

$95 is really good. I paid around $150 in southern Jersey at a golf cart place but needed them in a pinch and did not have time to shop around.

Re: Trojan T-105 6v Batteries

Another option, instead of (10) T105 at $1300 for about 400 cycles at 50% DOD for 1100 a-hr (550 a-hr usable), maybe (4) LiFePO4 700 a-hr at $2240 for 2000 cycles at 80% DOD (560 a-hr usable).

I believe it's about finding the cheapest option here... I mean the option that requires the least money upfront, because all the better options are ignored

Re: Trojan T-105 6v Batteries

Bob:

The price of the 3 V, 700 AH Li battery at the site you referenced is $560 each!!!

And how do you charge a battery that requires 4 V per battery? That is 16 V for four in series. Your standard 12 V marine charger or inverter/charger isn't going to work.

Re: Trojan T-105 6v Batteries

Nominal voltage is 3.2, so (4) in series is your 12 volt battery. Here are two that give my electric kayak an 80 nm range instead of the 16~18 mile range of a group 27 LA at the same weight.



One for size reference.

Re: Trojan T-105 6v Batteries

the T605 batteries are pretty much the same as the T105 but at a better price.

I though cheapest option in the long run. A leather jacket made of pressed cow dung would be cheap up front, but won't last long.

I've done lead acid for 25 years of off the grid and EVs, now that LiFePO4 have dropped in price, I'm never going back to lead.

Lead is dead.

I'm looking for the best price around, preferrably around the Annapolis/Baltimore area.
Anybody with good information to help?

It's cold enough for Santa Clause so I'm hoping he may still be doing late deliveries

Let's see, qty 10 and you are working on a boat. that makes you a boat builder professional. Find a distributor that will work with you at wholesale cost.

I like Deka golfcart batteries but Trojan is great too (perhaps better?). Or even Rolls renewable energy (mind the footprint).

I currently use 4 Deka GC batteries and expect to change out to 6 L16 when these wear out. For me the plan would be to build a battery box that can hold GC or L16 with shims as needed....

Regards

This was the subject of earlier posts last year. Someone was able to purchase the 105's in the Ft. Lauderdale area for far less than available here in the north east. MaineSail was so impressed he even thought of trucking some back to Maine.

The only reason for this post is to share what appears that 105's are available with great savings in many places in Florida.

Re: Trojan T-105 6v Batteries

I'm skeptical of lot of these stories of cheap T-105s. After awhile they begin to take on the aura of a Big Foot sighting :-)

A close friend, a professional in the yacht maintenance business and an ABYC master technician, just bought a bunch of them a few days ago.

Cheapest prices he could find in southern Florida:

Fresh T-105s, delivered to boat $132

Fresh T-105REs (new model), delivered to boat $167

In these parts (Chesapeake), fresh T-105s for $125-130 are a very good price.

FWIW,

Bill

Re: Trojan T-105 6v Batteries

I have been using Stevens BW in Annapolis for many years. On the corner od Chinquapin Round Rd. and Forest Dr(RT 665). They will make a good deal for 10 units.

The only place I like more is Indian River Battery in Vero Beach Fl. They deliver to the dock! No heavy lifting!
