Re: antigravity battery swelling
I used Antigravity XPS SC1 (4 cell) battery in my 2009 Buell XB12Scg about a few weeks with no issues. Then I swapped to Antigravity 8 cell battery because of XPS 4 cell battery is too weak to crank 1200cc V-twin engine. I have no issues with Antigravity 8 cell battery yet after half year of using it. Buell rectifier maintains 14.4 volts voltage, I believe this is maximum voltage you should maintain with LiFePo4 battery. Antigravity mentioned about it on their website. I also have voltmeter gauge installed on the motorcycle to monitor voltage during riding because of I had issues with voltage regulator before.
Also small size Antigravity batteries do not have batteries management system, so they may fail earlier than normal size LiFePo4 batteries.
Follow the rules from Antigravity manual. Use appropriate 14.5V VR. Find the coldest spot for the battery on the motorcycle, do not expose the battery to the heat. Make sure your accesories do not drain battery and rectifier power is enought to feed the battery and accessories. Hook the battery to special LiFePo4 charger once per a few weeks to not let it discharge too low. Make sure your motorcycle does not have parasitic draws. Do not hook battery instantly after riding on charger when it is warm, let the battery cool down to room temperature before charging it.
