TPE Lithium Battery YTX7L-BS 12V4AH 320CCA for Motorcycles & ATVs – Smart BMS, LCD Display, LiFePO4 Engine Start

A wee bit big for my application but a easy mount modification and it was fine and dandy

Identical fit for my Honda 3000 generator with Yuasa YTZ10S lead acid battery. Super powerful and lithium will stay charged for long periods of inactivity. Plus, this battery cost 1/2 as much as the Yuasa OEM battery. Win/Win! Built in voltage tester is another Win!

Do not buy this battery I bought it in April 2025 this year and it's all ready not working in 3 months it will not take a charge and I know it's the battery as I have even had it tested and before that I even put it in to my other and friends atv's and still nothen and the atv's are all ride able as we was all going riding so for me to get riding i had to strap a car battery to my rack and the atv started rate up with no problems I've tried getting intouch with the seller and nothen no answer

The battery is extreamly light weight and great in size. The added voltage meter is excellent so you can know you battery life. Super easy to set up as it’s just a positive and negative. Absolutely will buy another if needed.

It is working. This is crazy small and unbelievably light. I installed it in our quad, a 325cc. It starts right up. Push the button on the top and it shows you the voltage, ha. My concern is that it is showing 15v while charging in the quad. The documentation says to not charge it over 14.6. I hope this is ok or that the battery is able to self regulate. We'll see.

This worked perfect on our Honda side by side

Works fine very light

I had this for a month and it became defective just days out of the 30 day amazon window. Although it shows the correct voltage, it cant deliver greater than an amp of energy. The seller seems to have no warranty section on their website and no other contact other than a sales email. As of now, they have ignored me. Two of the MOSFETs were roasted all the way through. The battery is using the tiniest pouch cells sitting in nearly an inch of epoxy. You probably could have put 3x the pouch cells in this small enclosure and still had space leftover. No heatsinks on the MOSFETS? The wire gauges, soldering, and the rest of the construction seemed rather stout I will admit.
