Hello,
Same here.

Hello,
The battery is LFP, and now 7Kwh.

Hello,
Found some info from used LFP battery for sale. It seems that it is 7kWh and not 5,5 kWh as communicated in the manuals and most web pages. It is 51,52V, and consist of 3,22V modules. The advantages of this REPT battery that it is more robust and can take up to 6000 cycles or more before the degradation reaches 80%, but the cold temperature performance is not as good as in the NMC version used up to 2023. Especialy at any sub 0 temperatures.

Based on some other materials it seems that the new Rept 6kWh LFP battery is using 1P16S modules instead of 3P12S structure in the E4V NMC batteries.
So one module capacity has to be apr 110-120Ah
-
When the PTC heater is ON, it uses apr 19-20 A from 48 V battery including the fan. I thik the heater must be around 900W

Has anyone ever looked at the existing heating system? What are the performance values? According to the feeling, there is a annealing in it...
If something reasonable could be installed, the problems would be elegantly solved and in the 12V electrical system.
Greetings!

Hi
The heating is 48V the control is 12V.

My experience is, that after several days with outside temperatures below 0 C°, the topolino does not charge, to be precise charging stops after few secounds when plugged in.Found some infotmation regarding the "new" LFP modules in Rept battery used in AMI, Rocks & Topolino.
