Features

  • NOTE: Lead Acid battery chargers MUST NOT be used on LiFePO4 batteries because they cannot monitor and output the correct CC and CV as needed and they always default to a trickle FLOAT charge. You must only use a specified LiFePO4 charger.
  • Smart BMS Protection: Maxlithium has a built-in battery management system (BMS), which can automatically protect your battery from overcurrent and short circuits, overcharge, and discharge, as well as low-temperature and high-temperature protection (-20C~60C), preventing accidents occur, providing maximum safety protection to your battery for long-lasting reliability.
  • Safe and Reliable: Maxlitium's LiFePO4 battery does not contain any lead acid, requires no activation, and does not require water. It has higher chemical stability and is not prone to heat out of control. Even if it is broken down, it will not ignite due to overheating. It is superior to lead-acid batteries in almost all aspects. With its own BMS intelligent protection function, it can be charged and installed at any time.
  • Reliable terminal quality: Maxlithium Lithium Battery terminals are of better quality, can withstand greater current, and better protect your battery and motorcycle; more convenient installation - you can choose to install from different angles from the front, side, top and internal thread.
  • Portable and Efficient: Compared with lead-acid batteries, Maxlithium's lithium iron phosphate batteries have higher energy density and greater power, but the weight is at most 1/2 of lead-acid batteries. The lithium-ion power battery weighs only 2.85 pounds (about 1.29 kilograms). Provides more than 480CA, more than 50000 starts, and more than 2000 charging cycles for higher capacity and longer life.
  • Wider compatibility: MaxLithium lithium iron phosphate batteries can replace most batteries: YTX12-BS, YTX14-BS, YTX16-BS, YTX20L-BS, YTX20-BS, YTX20H-BS, YTX20HL-BS; And it is compatible with most power sports brands - Aprilla, BMW, Buell, Ducati, Harley-Davidson, Indian, Triumph, KTM, Argo, Can-Am, Honda, Husqvarna, Kawasaki, Suzuki, Arctic Cat, BRP, Waverunner, Polaris, Vespa - motorcycles, ATVs, UTVs, PWCs, quads, 4 wheelers, wave runners, scooters, riding lawn mowers, generators and more.

  • Lightweight
Size: 210CA YTX4L/YTZ5S/YTX5L/YTZ6/YTX7S/YTX7L-BS
This battery was smaller than the gel cell I replaced but has performed flawlessly. It maintains charge and gives me peace of mind that I do t have to worry about my battery any longer. I've only had it in for a year and a half so far, but it holds voltage well

  • Super light and TONS of cranking power
Size: 360CA YTX9-BS/YTX12/YTZ14S-BS
I always use lithium batteries in my scooters and this one is great. Much more cranking power than the leas acid that it replaced and a lot lighter as well.

  • Failed after 1 month
Size: 480CA YTX12/YTX14/YTX16/YTX20-BS
Battery worked fine for one month. Came out and the bike had no power. Verified voltage on battery and battery would not power anything 12volts. I have two bikes and it wouldn't power anything. Verified it was not the bike with a spare battery. I attempted to contact the seller for warranty and they never responded. Luckily Amazon services made the sellers mistake right and issued me a refund and return. Will not buy another. ... show more

  • So far so good
Size: 210CA YTX4L/YTZ5S/YTX5L/YTZ6/YTX7S/YTX7L-BS
I am using one of these in a CRF 150F and am likely replacing a older Tusk Lithium in a WR450F. I will see how well they hold up.

  • Upgrade
Size: 480CA YTX12/YTX14/YTX16/YTX20-BS
So far this has been a great upgrade to my quad. We use the quad for a pusher to fire our outlaw kart so we start the quad a ton during the night and haven’t had a problem with it going dead like the agm’s or lead acid battery’s.

  • Works great
Size: 150CA YTX4L/YTX5L/YTZ5S-BS/YTZ6-BS
Light weight powerful but very small and had to buy a separate charger for if I killed it

  • Terminals a little larger than usual, but works great
Size: 360CA YTX9-BS/YTX12/YTZ14S-BS
I installed this battery on a Honda Shadow Aero 2005, the cable connectors have little tabs that usually hug the battery terminal but on this battery the terminal is larger than the wings so I had to crank them down to flatten. Besides that this battery seems too good to be true but so far it's been the real deal. I didn't put a longevity rating because I've only been running it a couple weeks, but it's started the bike nearly instantly every time and it's unbelievably lightweight. I've been very impressed for the price so far and I'm looking forward to not worrying about the bike not getting used for a bit and not killing the battery altogether like on my old SLA batteries. The spacers worked well in getting the right height for my battery tray. I would highly recommend this battery to anyone sick of replacing their motorcycle battery once a year. ... show more
