Lithium Battery Smart - Options to prevent battery dropping below 5°C and not charging

Hi,

I was thinking of getting some low power (14W) vivarium heating pads and putting them under my Smart Lithium Batteries then using a thermostat to control them (set at say 10°C) to prevent them getting lower than 5°C over the winter.


Anyone have any experience or comments?

I am making a small (closable) additional outlet on my Webasto heater to the battery bay and I can switch the powersource of the battery from housebank to bowthruster bank (which a tradditional battery bank). The last is being trickle charged from a multiplus.

I have done just this. I have four batteries and 4 x 15W Silicone Rubber Heat Mats.

There was a good article linked from a Victron Blog entry earlier this year that is worth a read.

@Bathnm,

Would you mind to share the brand of rubber heat mats and possibly a few images how you wrap them around the SmartLithium?
Are the heat pads thermo controlled in any way, internally or externally?
