Review: Updated My Review to Excellent Product - I received the product and the top cover of the case was not attached all the way around. It had come loose during manufacture. I wrote a review and gave it a 3 stars for this reason. But the company sent an email apologizing for the inconvenience of the defect and promised to send another battery. The battery I first received was of very good quality except for the problem with the top. It charged up in no more than 30 minutes and appeared to be of good quality. I was only disappointed with the top because I thought a problem might develop with moisture or that the top might come off completely. Since the company is replacing the product I am happy and have raised my rating to 5 stars. ## Features - 【Superior Performance】: Lithium iron phosphate battery has high energy density, Long cycle life, Good safety performance, No memory effect, etc. NERMAK LiFePO4 battery has built-in BMS protection to prevent overcharge, Over-discharge, Over-current and short circuit, and excessive low self-discharge rate ensuring up to 1-year maintenance-free storage. - 【Long life & light weight】: 2000+ cycles of lithium-ion batteries are no problem, while traditional lead-acid batteries only have 200-500 cycles.

The advantages of these are they will tolerate 80% discharge per cycle before any degradation (as opposed to 50% for lead-acid). and they offer many times the cycles. I can’t speak to their suitability for your application, though. They’re only 10AH each. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent Customer Service and Reliable Battery! *by O***N on August 2, 2023* I recently purchased a battery from this seller, and while I initially encountered a problem with the product, their customer service team turned the situation around completely!
