Fogstar Batteries

[t6blo]

Interesting thing this morning, I assumed the Fogstar Drift had a heater but it didn’t appear to be charging - or was it?

The heater kicks in below zero C.

Charge is blocked below zero C.

Outgoing power is ok to -20c

Heater is shut off at 5degc

Mine shows heater symbol on side of battery.....sb230.

Does yours?


Also you battery in the pic shows 100% and 6detc.

When I came out to the van later and the temp was higher it charged fine and topped right up.
According to research, the heater pad(s) are only powered by the incoming feed from the Renogy not from the battery itself and if I’d have waited a few more mins I think just over 6degC is when it would have allowed charging again.

Yep that's it.

Heater is powered from incoming charge source.

Gave it a bit longer this morning and now charging nicely even with outside temp of 0.5degC showing on van thermometer

your battery is showing:

its 100% SoC

but still taking 24.1A charge, ( so its still charging, the BMS is calibrating to 100% top end)

and its internal temp is 8.3degC

++++++++++

here was mine this morning . .


92% SoC

charging at 25.1A

3.2degC temp

so far the battery hasn't been cold enough to see the charge temp blocking . . . maybe tomoz?

My heater kicked in this morning

Charge briefly kicked in when engine started then a new icon appeared and it went to 0 amps

Gradually heated up battery, charge kicked back in at 7.3 degrees

Took about 25 mins to heat up

 

[Dellmassive]

I was just above 0.3c

No heater yet.

Just normal charge.
