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

Ordered this to replace the lead acid battery in my mower, it was a drop-in replacement, even though it's significantly smaller than the battery it's replacing. It doesn't have a huge capacity, but it does have good cranking strength and starts my mower with no problems. Overall, a great small form-factor battery with high cracking potential.

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.

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.

These newer technology batteries just keep getting better, smaller, and more powerful. This battery has an impressive life cycle of 2500 cycles which beats the pants off any old style lead acid battery I still have in use just waiting to get replaced. This battery is going into one of my lawn tractors in which the old AGM battery has seen the best of its days and ready for recycling. This has more cold cranking amp power than my old AGM battery in a much smaller size too. Plus this thing just looks so darn cool. It is a shame to have it under the hood where never to be seen.

This little battery is a lot lighter and than its equivalent AGM. It will crank and run my 200cc scooter just fine. Capacity wise this is less than half the capacity of my regular battery. That is the problem. If I run accessories with the engine off, this will not last as long as the other one. I also cannot go as long between charging or running the bike due to its built in security system that is drawing power all the time. I didn't take that into account so I can't blame the battery. This battery is perfectly fine to start and run small bikes and to last all winter without a maintenance charger if your bike doesn't draw power all the time like mine. It saves weight and gives more CCA than regular batteries this size. I also like the built in voltage meter on the top. Its a good small engine battery, just be sure the capacity (3-4Ah) is enough for your application.

Motorcycle batteries are great for providing 12V power in situations where space and weight is at a premium. I really love these lithium iron phosphate (LiFePO4) batteries for their light weight, high capacity, reliability, and omnidirectional positioning. I realize that these lithium based batteries still have their hazards, but I prefer them over lead-acid for sure. The terminals are easily accessible and well designed. With threaded holes milled into 5 of 6 sides of each cube shaped brass square, the user can make the connections on the front, top or sides with the included bolts as needed. A digital display inset into the top cover to indicate current voltage charge can be activated by holding the adjacent button. Very handy. All-in-all, I love this little battery and would definitely recommend it.

Second TPE battery I have tried and I will be going back to lithium batteries supplied from Batteries Plus. First battery was the 320cca version, this battery claims 300cca. I charged both with a 14.6v 1amp LifePO4 charger from NOCO. Put the battery into my Lifan KPM motorcycle, turn the key to prime the fuel pump, press the start button, bike barely turns over and voltage of the battery drops to 11. Several attemps and the bike never starts. Contact TPE and they tell me they have never heard of this problem before and to charge the battery with a 14.6v charger, a full battery should have 14.6 volts... well guess what the resting full charge of BOTH batteries I received are? They are only 13.3 volts, nowhere close to their magical 14.6 volts. Searching reviews for TPE batteries shows several other having this issue dating back 5 or more years... there are also several reviews where the battery is not producing the cranking amps claimed and worse case several batteries have started a fire in the vehicle... so TPE should know of these issues as they are publicly available for all to read and see. For the poor customer service and also for supplying a clear fire hazard, I cannot in good faith recommend you or anyone else buy and use any TPE branded products. Go to Batteries Plus and get a X2 Lithium battery. They don't currently offer the full range of powersport sizes, but you can usually find one that will fit your applications Amp Hour Reserve and Cranking Amps you will need.
