LITHIUM POSITIVES After nine months of living in our van full-time, we’d had no issues with our lithium setup, and we’ve since discovered that the scenario we described above was not battery-related, but rather a wiring issue. Let me explain… We were parked at an RV-friendly site in outback Queensland. It was the middle of the night, so we couldn’t just whip out the generator and turn it on to revive our power source. So in the darkness, stressed and confused, we sought what little sleep we could and at the break of day woke the kids and drove onto a roadside stop where we could run the generator and hopefully make some calls for help. Being a Sunday, though, we couldn’t find much except for what the internet was telling us. We were advised to disconnect the sensors, test the voltage of each battery to determine if they were shutting down as a safety mechanism due to one of the batteries being faulty, then reconnect all the sensors and charge up to 100 per cent and see how they go. Luckily for us, Wayne carries a voltage tester, so he was able to carry this out himself. We noted that all the batteries were registering the same voltage and appeared to be fine after being fully charged with the generator. When we finally were able to get someone on the phone, we were told that it was most likely due to the fact we had been free-camping for a whole month and not allowed the batteries a ‘decent’ charge up on 240V power (although we had almost full charge via solar and/or generator every night during that period. We couldn’t see how the charge from a generator or solar was considered ‘inferior’. To us, full charge was full charge, regardless of the means of input. So off we went to a powered site to allow the batteries a solid 240V charge. Our van was plugged in for three nights. DEJA VU Just shy of four weeks later, in another unpowered campsite, we awoke in the middle of the night to the same alarm. This time, the voltage dropped even faster and within half an hour the power had completely shut off. We were stressed out, tired, and confused once again. The only positive aspect was that at least it was night time so our compressor fridge was still able to stay cold. Wayne inspects the BMS – what could the problem be? 50 \
