New V3i 18650 battery holder. What U think?

[nalc472]

I talked my Ukraine buddy to make a V3I holder for Lithium 18650 Batteries. This will allow U to detect for weeks.
What Do U think about this holder? That will shave off at least 8 oz of weight.

I like it!

This guy seems to be able to make anything on a 3d printer. I do not have a V3i anymore but remember it likes to eat batteries. It will make it a lot lighter and last a very long time.

Sounds good. But what about coil balance? What batteries capacity?

 

[nalc472]

You can put 3400mah 18650 flat tops. Voltage will start at around 12.5 total and go down from there. My etrac with 3 batteries goes 30+ hours on one charge. You should be able to buy 3 batteries, charger, and device and spend about 50-55 dollars.

I know for me if I can shed 8 oz off my weight of my detector the balance is only easier for me.

Pretty much a copy of the RNB battery pack. It would be good or even better if it had the plug for charging it made into it like the RNB.

 

[nalc472]

For about 55.00 all in I take my batteries out of the device every say 30 hours of use. It is no big deal to charge.

The real question left is how long the battery hungery V3i will run. Likely much different than an Etrac. Otherwise, it's a nice design.

 

[shelton7522]

If you change standard battery pack internals for new AA cells you don't need lithium cells... On max settings 6-7 hours minimum.

The RNB has three 3.7v lithium batteries and the one I have is a 3100mah. I hunt for 2-3 hours or more 3-4 times per week and my V3i lasts almost 2 weeks of this usage before I have to charge the battery. I am sure with good quality batteries used in this setup would yield 30 hours.

What is price of this holder?

 

[nalc472]

He is going to sell it for I believe 22.00 Plus Shipping. If U put 3400mah batteries in this thing it will rock. I use 18650B 3400mah 3.7 Panasonic made in Japan batteries in my holder for my E-trac. I am sitting on 12.00V after 8 hours of hunting.

What's the battery dimensions compared to Eneloop AA batts?

Nevermind. Found it.

 

[nalc472]

These are lots bigger. Only 3 18650B create tons of power.

 

[5900_XL-1]

Thanks. Question was asked to me about it. Is there circuit protection built into this holder?

 

[romanchuksl]

No, just contacts and wires. Better use 18650 with protection(69mm. length)

 

[nalc472]

The detectors have a over protection cutoff and under cutoff. However if U can use a protected battery use it.

I like this option very much. When and where will this holder be available?

 

[romanchuksl]

I have sent few holders to test yesterday. Maybe it will be available next week on ebay.
