Default Etrac and lithium ion rechargeables

I was looking to see if the rnb innovations battery pack was available, and I appears everywhere I looked is out of stock. I wondered if anyone has went and bought the rechargeable lithium ion AAs that you can get at the big box stores and compared them to see if they are as good as the rnb pack? Both are lithium ion, so just wondered if they are comparable.

Thanks for any info you can provide.

A quick $15 fix for the FBS machines is 8 AA NiMH rechargeable batteries from Harbor Freight, along with a terminal spring from a old TV remote to complete the connection on one end...installed in the original rechargeable battery pack case. It'll now last for at least 18 hours on a charge, and the factory charger can still be used...

Try the rechargeable 1.5v LiOn AA cells that are much better than the NiMh 1.2 v batteries. Lighter too.

Check these out:

https://www.amazon.com/dp/B08F3FC3G4...2s9dHJ1ZQ&th=1

Charge anywhere you have access to USB power, or use a power pack.

Hope this helps...

Thanks for the link. I see that on the rnb innovations website that the battery pack is in stock. Still undecided which way I will go, but I appreciate the information.

A bunch of dealers have the rnb innovations back in stock now.

Make sure you check the pricing. I just bought one and payed way to much.

Nevermind, I found it. I didnt know they had the 3400 model. Its cheaper than the 3100, their older version. Thanks for the heads up..
