Electropolishing - Wikipedia
Saved by uncleflo on April 3rd, 2021.
Electropolishing, also known as electrochemical polishing, anodic polishing, or electrolytic polishing (especially in the metallography field), is an electrochemical process that removes material from a metallic workpiece, reducing the surface roughness by levelling micro-peaks and valleys, improving the surface finish. It is used to polish, passivate, and deburr metal parts. It is often described as the reverse of electroplating. It may be used in lieu of abrasive fine polishing in microstructural preparation. Typically, the work-piece is immersed in a temperature-controlled bath of electrolyte and serves as the anode; it is connected to the positive terminal of a DC power supply, the negative terminal being attached to the cathode. A current passes from the anode, where metal on the surface is oxidised and dissolved in the electrolyte, to the cathode. At the cathode, a reduction reaction occurs, which normally produces hydrogen. Electrolytes used for electropolishing are most often concentrated acid solutions having a high viscosity, such as mixtures of sulfuric acid and phosphoric acid. Other electropolishing electrolytes reported in the literature include mixtures of perchloric acid with acetic anhydride (which has caused fatal explosions), and methanolic solutions of sulfuric acid.

Lithium iron phosphate battery NX LiFePO4 POWER UN38.3 (1280Wh) 12V 100Ah M8-F - AML9138 | Allbatteries.co.uk
Saved by uncleflo on September 9th, 2019.
LiFePO4 technology differs from lead acid technology, but is perfectly compatible with your device. This battery can therefore be easily installed and does not require any modifications on your behalf. What¿s more, this LiFePO4 battery can be charged with you current lead acid battery charger. This 12V lithium iron phosphate battery is equipped with a BMS (Battery Management System) which protects the battery against short circuits, overcharge and deep discharge. The BMS also balances cells to increase battery life, improve performance and protect against mishandling.
