Lithium battery for caravan, motorhome or boat. Lithium batteries are not only lighter but also have a significantly longer life and higher performance than lead batteries. So load 30 kg of extra equipment instead of 30 kg of lead battery while you get a battery that has a lifespan that is up to 5 times longer than for a regular lead battery. Thanks to the high discharge capacity and stable voltage of the lithium technology, this battery corresponds to a 12V 150 Ah lead battery.
READ MORENominal capacity: 1216 Wh (90 Ah)
Outgoing capacity: 12V / 93Ah
Rated voltage: 12.8V
Weight: 10.5 kg
Life span: 15 years (80% capacity after 4000 cycles)
Battery with very high capacity, low weight, compact size and significantly longer life than a traditional lead-acid battery. This LiFePO4 battery from Meritsun is ideal for use in motorhomes, caravans, boats or other leisure products such as electric boat engines. The advantage of the lithium battery is partly that it charges much faster than a regular battery and you can also use up to 90% of the current in the battery compared to about 50% from a traditional battery. This allows you to buy a lithium battery with less amperage than your regular battery and still get the same power.
BMS
The battery has a built-in BMS (Battery Management System) for maximum safety and longevity. Thanks to the built-in electronics, the battery can be charged via a standard constant voltage charger, solar cell regulator etc.
Bluetooth
Thanks to a bluetooth connection, you can via Meritsun's app keep track of the status and charge of the battery directly in the phone (Android / Iphone).
Meritsun
The Meritsun batteries are manufactured by Meritech Power Limited, which was founded in 1999 and has over 500 employees. They have a self-developed and self-manufactured BMS with components from Japan and Korea. Their batteries are sold under several brands including Skanbat.
Calculation example for life cycle cost:
100Ah lead battery, price SEK 2,500, 700 charge bikes = SEK 3.57 per charge bike.
Meritsun, price SEK 10,495, 4000 charge bikes = SEK 2.63 per charge bike.

Meritsun BMS can handle virtually all battery chargers and solar panels and works directly to the caravan / caravan charger. It can handle all external chargers that provide an even current during charging. With so-called smart chargers that pulsate the current to recondition the lead cells / maintenance charge, the BMS will turn off the charge. However, many smart chargers can be switched to a non-pulsating charge. For those of you who charge with solar cells, the battery can handle up to 100A.
