What are EnerAmp Batteries?

EnerAmp Batteries are our own line of LiFePO4 Batteries.  We launched EnerAmp Batteries in Febuary of 2021 with the mission to provide batteries to USA-based customers, with quick shipping times, lower shipping rates, rigorous quality control, US based 10 year warranty and English technical support. EnerAmp cells are proudly assembled in Los Angeles, California (USA) and are interconnected with Buss Bars fabricated in Manteca, California.


Why not buy cheap cells from China?

It has been our experience that when you buy cells from China, it may appear that they are far less expensive – this is nothing but false!  Often times you will find a great deal on batteries, but the shipping to get them from China costs nearly as much as the batteries themselves!  When you order EnerAmp batteries you will expect to have them shipped within 24 hours, and at your door in 2-7 days by FedEx Ground, depending on how far from our warehouse in California you are located.  We even offer free local pickup!  No need to worry about shipping by sea and waiting 3 months just to realize you got ripped off with fake, B-Grade, used, or even totally faulty cells!  We also offer standard payment methods, so no need to setup a sketchy wire transfer that cannot be cancelled.  We accept all major credit cards as well as PayPal!

Current Connected has a industry-leading 10 year warranty that puts the customer first.  You can read the full policy here.  If you are having trouble getting your system up and running, we are available during normal business hours (9-5 PST), and we can help you both by E-mail or over the phone!  Try getting that from a China-based vendor.

Cell Quality

We do not sell any used products.  We assure you that every battery is a top-quality, brand new cell.  We do not call things by grade, simply because “grade-a” is ambiguous and has no standard definition in industry. When you receive an EA170, you can test and observe that a 170Ah cell will output an actual capacity of 173-175Ah at 100% DOD (3.65v – 2.8v).  EnerAmp cells are rated at 80% remaining capacity after 5000 cycles at 80% depth of discharge.  If you discharge to 100% depth of discharge, you can expect to see a 20% reduction in cycle life.
