Lithium battery for caravans, motorhomes or boats with built-in heating system which allows it to be charged even during the winter. Sunwind Lithium Heat 100AH has a BMS (battery management system) that ensures and protects the battery against incorrect charging, high temperatures and overloading. Thanks to its BMS, you can replace your lead-acid battery (excluding starter batteries) directly without having to make any adjustments to the electrical system.
READ MORENominal capacity: 1280 Wh (100 Ah)
Output capacity: 12V/96 Ah
Nominal voltage: 12.8V
Weight: 12.2 kg
Life span: approximately 15 years
Battery with high capacity, low weight, compact size and significantly longer lifespan than a traditional lead-acid battery. A unique feature of this LiFePO4 battery from Sunwind is that it has a built-in heating system that heats up the battery before charging if needed. It is therefore particularly suitable for those of you who use your caravan/motorhome even in the colder parts of the year. The advantage of the lithium battery is that it charges significantly faster than a regular battery and you can use almost the entire battery capacity compared to about 50% with a traditional battery. This means that you can buy a lithium battery with less Ah than your regular battery and still get the same effect.
The battery has a built-in BMS (Battery Management System) for maximum safety and lifespan. Thanks to the built-in electronics, the battery can be charged using a regular constant-voltage charger, solar charge controller, etc.
Bluetooth
The BMS also has a Bluetooth connection so you can connect it to your phone to see the status of the battery. You can see:

Sunwind's BMS is compatible with almost all battery chargers and solar panels, and works directly with the motorhome/caravan charger. It can handle all external chargers that provide a steady current during charging. With so-called smart chargers that pulse the current to recondition the lead cells/maintain charge, the BMS will shut off the charging. But many smart chargers can be switched to non-pulsing charging. For those who charge with solar panels, the battery can handle up to 80A.
