Warning on using Lithium Ion batteries in E-trac

[Tony N (Michigan)]

I just now read this on the instructions for the E-trac:

Do not use rechargeable Lithium Ion batteries with your E-Trac.
They may damage the detector and void your warranty.
Rechargeable Lithium Ion batteries will give a combined
voltage above 13V and therefore cannot be used with E-Trac.
The detector has over-voltage protection and will not turn on
if the battery voltage is too high.

However, my ML-3100 RNB-INNOVATION.COM lithium ion battery pack states its combined voltage is 12.5v. So I should be okay?

They're wonderful Tony , don't worry about it. many of us have been using them for some time with no issue. The first lithium batteries(non rechargeable) had higher voltages and , although I don't think it was anything the regulator couldn't compensate for , Minelab must have used that warning to cover their a$$. RNB batteries are terrific

Yea, I wish I had RNB's years ago. It would have saved me a lot of money and time with all my rechargeable batteries and all the time it too to recharge them.
The RNB's are incredible! I can go a few days without recharging and .. . it only takes a couple hours to recharge them! Well worth the money!

RNB Batteries are the single best investment one can make in a detector !!! The best of the best.

How do you use these in a sealed battery?
Thanks

The aftermarket RNB 3100 battery is a series of 3 18650 Lion batteries in a case the same configuration as the stock battery. They come with their own charger also. You will not make a better investment for the eTrac than this item if you wind up using the machine a lot. Like “every day” a lot.

Thanks IDXMonster.
Man, I haven't been out for a long time now. Haven't been out detecting this year yet. Hard to find new places.
