Designed for harsh environments such as rainy or marine, or dusty and wet conditions, this battery offers worry-free and long-lasting performance with an extended lifespan.in addition to marine starting scenarios, it can also be additionally adapted to fuel powerd riding lawn mowers.
Perfect Replacement for Lead-acid Starting Batteries
LiTime 12V 20Ah lithium iron phosphate marine starting battery adopts automotive grade lithium iron phosphate starting cells, which has higher energy density compared to lead-acid batteries. This means more power in a compact size, ideal for powering your devices while reducing the environmental impact. It weighs 9.68 lbs and is BCI Group U1 size. Its lightweight can lessen the burden of your boat so that you can drive it smoother, faster, and more maneuverable. Besides, one LiTime LiFePO4 battery can release 256Wh of energy, which provides you with a 2X energy of lead-acid batteries.
Three Fast Charging Ways
With the LiTime 12V 20Ah starting battery, you can choose from three convenient charging options to suit your needs. Whether you use LiFePO4 battery charger, generator, or outboard alternator, you can fully charge your battery efficiently and reliably.We recommend 0.5C(10A) charging current,about 2 hours to charge full.And only 40 minutes to fully charged if charge with a maximum continuous charge current of 1.5C (30A).Compared with lead-acid battery charging (usually charging current is 0.1C), the max. charging current of LiFePO4 battery can shorten the charging time by 15 times, so it can be charged with more power in a shorter period of time, which can satisfy the demand of going out in a hurry.
