Lithium batteries
 
We just became authorized dealers of lithium batteries

We are thrilled to part of this emerging technology.

Moreover, with the addition of Solar this will be a fantastic option.

We have proven solar with lead acid standard Trojans can get you 65-70 miles

Lithium will extend that range for sure. For starters they save over 200 lbs (as in weight/distance)

I teamed up with Lithium Boost, they have developed this technology system better than others in this vertical their systems include chargers, Battery Management System (BMS), gauges.

The superiority of lithium-ion batteries is clear due to their dramatic lighter weight, significant longer life-cycle, elimination of maintenance hassle and cost, shorter charge times, longer range, and in the bottom line - lower total life cost.

15 year battery life span,
fast charge time if plug into shore power 1 hour is average.

Now if you add solar the whole system gets a 30% tax rebate.

I'll be looking for a open minded owner who want's to try it at a great discount.

the big question has always been cost.

Well here's the deal the only other dealer in FL is offering these at $6,500 plus tax or $7,000.

That price was a big turn off to most folks

We will be at about $4250 for the 100ah system

Now that becomes $2975 if you add solar, best of all no sales tax.

How is it that by adding solar the price goes down?

jimbo2012 04-06-2016 09:06 AM

Federal tax rebate program 30%

Dr Winston O Boogie jr 04-06-2016 09:14 AM

Does the $4250 include the solar system? 70% of $4250 is $2975. Are you forgetting to add in the cost of the solar?

How does the rebate work? Do you send in copies of your receipt to some government agency and they send you a check?

Sorry for not being clearer

the Lithium setup installed is $4250, if you don't get the solar option at that time, you must add tax to that that amount.
So $4547.

With Solar savings
Lithium set $4250 x 30% = $1275
Now add solar $789 x 30% = $236.70

total with solar $5039 after rebate + no sales tax + $3527

so grand total $3527


ADVANTAGES OF LITHIUM ION BATTERIES
  • High power to weight ratio as compared to Lead acidic, Nicd, NiFe.
  • Less space required for installation.
  • These batteries are maintenance free.
  • High cycle life between 5000-7000 cycles (For especially designed Lithium Ion storage batteries for the solar applications).
  • High charging and discharging efficiency, above 95%.
  • Capable to produce most of its stored energy with very high discharging rate.
  • Depth of discharge is 80% for optimum cycle life.
  • Capable to produce 100% of its stored energy.
  • Tolerate high charging rates.
  • Long service life between 10-20 years (Depends on the brand).
  • Very low self discharging nature.
  • never lose their charge if stored for months at a time (as in snow birds)
  • Wide temperature range for discharging.
  • No memory effect, no need to fully discharge before recharging as other nickel batteries require doing that.

Is a lithium battery charger included or purchased separately? Can one use their existing charger?

mulligan 04-06-2016 12:49 PM

Aren't those the ones that explode ??

It is included,


you can not use your existing charger what so ever.

Jima64 04-06-2016 06:33 PM

Could you explain the rebate part in more detail?

jimbo2012 04-06-2016 06:49 PM

Sure IRS form

line 2b allows for a 30% tax credit for investing in solar. The solar panel and the batteries are all part of a solar system on the cart.

Before I start into some facts, I find this question somewhat funny coming from people who have been sitting on top of tank of liquid gasoline as they travel down the road. It is highly flammable and can explode if the conditions are right.

What if a gas golf cart was hit by car?


If your gas tank is punctured it is sure to spill all over the ground and create an even bigger hazard. In a report from 2005 over 266,000 gasoline related car fires killed over 566 people. So with that said, I will begin to approach the subject of the dangers of lithium ion fires.

The metal lithium is highly flammable and burns very hot.
But lithium ion cells like those use in most electric cars these days do not actually contain metallic lithium.

So not the same issue with these batteries.

Rechargeable, lithium ion cells utilize lithium ions that are intercalated into graphite, lithium metal oxides and/or lithium salts.

There is no metallic lithium in a lithium ion battery.

This means that they are much more stable than many of the earlier non-rechargeable lithium batteries which did contain metallic lithium.

One big safety factor in this is that you can use standard ABC fire extinguishers or water to put out a lithium ion battery fire.

It is in the charging process that they may be vulnerable.
If you over charge a lithium ion cell the cells will expand and become very hot.
If over charged to much, this heat will build up and cause the cell to ignite.
During the normal charging process the cells should not become hot.

This is why it is very important to have some kind of monitoring system hooked up to the cells while they are being charged to make sure that the charger shuts off automatically when they reach a fully charged state or if the cells become hot.

All of our systems have a State of the Art Battery Management system.


last point we are not using 4 large 12 volt battery packs to make 48 volts

We use 15 3.2volt batteries to get 48 volts,

so if there was a problem the battery mass is significantly smaller to cause damage.

A gas can in your garage offers a greater risk perhaps.


The way the battery charger works when plugged into you homes power automatically disconnects from the battery pack when full charge is reached.

they can't overcharge.

Got it Thanks

Jimbo, congrats on your new association with the Lithium battery folks. As one of the first to have converted from a lead based battery system to Lithium Ion power cells, I can't say how happy I am on the performance and the increased range I have on a single charge. I only wish I had had waited a couple of months to take advantage of your discounted pricing.

I was unaware of the solar discount on my taxes and am having my account looking into it to see if it's worth while to re file my 2015 returns. I would be happy to join you at your Town Square gatherings to show off what I have and talk about the advantages to anyone who might be interested. Please PM me about dates and times. This is the cart of the future and you are on the cutting edge.

jimbo2012 04-08-2016 07:08 AM

You must install the solar at that same time as the batteries on the same invoice.

But speak to your accountant to be sure

Thanks for your support :MOJE_whot:

We met a painting contractor who just joined the RC Flying Club that my husband belongs to. A few Saturdays ago he left the small lithium batteries that power model airplanes on charge while he and his family went to breakfast. He said the batteries felt "warm" but didn't think anything about it. Something went wrong and the house caught fire shortly after they had gone. My husband charges his lithium batteries in a sturdy metal container and only while he is at home and awake. So far so good.
