Hymer Europe introduced a new energy package that combines Lithium and AGM batteries. Although it has a very limited energy capacity (230 Ah) compared the huge banks some members of this forum have installed in their rigs, it is an original hybrid solution that could be an interesting transition toward the onerous all-Lithium systems. Aren't Tesla cars equiped with an AGM battery to keep the BMS system working?
It is composed of a 95 Ah AGM wired in parallel with a 135 Ah lithium battery.
Is it combining the best of both technologies or simply making it more complicated with limited benefits? Time will tell.
As mentioned in the press release:
...The lithium batteries undertake the majority of the charging cycles, whilst the lead batteries serve as backup storage devices.
…By connecting together two different battery systems, the entire winter-proof system can even be operated at temperatures below 5 °C, without any adverse impact on the lithium battery. This is because the operation of the entire system at lower temperatures is ensured by the lead battery, which is impervious to the cold.
