This is the NOCO 12V Lithium NLP30 battery. It's a 7.8Ah 12.8V (100Wh) LifePO4 Powersport Group 30 Battery with 700A starting current.
Great battery for many uses, including replacing your bike's lead-acid battery.
*The NOCO NLP30 replaces battery sizes: BTX30L, BTX30L-BS, EXT30L, GYZ32HL, YIX30L, and YIX30L-BS.
NOCO mentions it's an excellent replacement for a battery used in a motorcycle, ATV Quad, Jet Ski, 4 Wheeler, Lawn Mower, Tractor, Scooter, Generator Battery and more...
If you just can't wait for my review, you can get it at Amazon USA for $179.96, or here at Amazon UK for £159.26 GBP.
