Very impressive

I purchased two Group 31, 140 Ah batteries with Bluetooth for my 5 th wheel trailer. Very impressed with the quality and the documentation provided by LiTime. It’s amazing how quickly these can be recharged. I’ve done several charge/discharge bench tests and these perform very well.

Quality Products

I purchased both the Litime 12V 140ah bluetooth Lithium Deep Cycle Battery and the marine 10A Battery charger for my Canoe Trolling motor. I am 74 years old, the weigh of the AGM and Acid batteries are very heavy for me now. The LiTime Lithium Battery weighs about a third of the weigh of the others. Both products were delivered in a timely matter, packaging was excellent, both appear to be quality products, experienced no problems with the instructions, downloading the blue tooth app, charging took about 10 hours, charger did not over heat as others have posted. I would and do recommend these products to everyone.

It's amazing how much lighter the LiTime Mini batteries are, the conversion was easy, and the fit & finish on the LiTime Minis is great.
