  • There are newer LFP portable batteries with <10ms UPS switch times that charge quickly and will keep the power on longer. They also have much longer battery life’s (3000+ cycles) , and LFP cells don’t degrade the same when kept at 100% like other types, although you should still cycle them a few times a year.

    Bluetti makes some, the elite series has their latest UPS features. The non elite are slower and noisier.

    Its all fairly new and have been improving year over year. For example, earlier models may not have switched back on if power was out for a long time and it fully drained the battery. Now some models can turn back on.

    Edit: more details.

    Serhiy Beskrestnov, known by his call sign “Flash,” is the advisor on defense technology to the Ministry of Defense of Ukraine and the same analyst who identified the Starlink connection to the train attack earlier this week.

    Beskrestnov’s thread revealed a secondary challenge that is less dramatic but possibly more important for the long-term solution. Ukraine needs to collect complete information on all Starlink terminals in use across the Armed Forces, and soldiers have been reluctant to cooperate.

    The problem is straightforward. Many soldiers use volunteer-provided or personally purchased Starlink terminals. These aren’t on any official inventory. Soldiers fear that reporting them to their commanders will result in confiscation, failure to replace them, or other bureaucratic headaches. Beskrestnov was blunt about this, acknowledging that previous attempts to catalog military Starlink use had failed for exactly these reasons.

    This matters because any whitelist system only works if you know which terminals belong to friendly forces. Of the estimated 200,000 Starlink terminals operating in Ukraine, fewer than half were procured through official government channels, according to a December 2025 analysis by Militarnyi. The rest exist in a legal gray zone of private purchases, volunteer donations, and foreign sourcing.

    Beskrestnov promised to find a way to gather this information that earns soldiers’ trust. He also stressed that SpaceX is directly involved in the process and is actively assisting specialists from the Ministry of Defence.
