When it comes to lithium-ion batteries, there are several different types, including lithium iron phosphate (LFP) and ternary lithium batteries. Although LFP batteries are some of the most durable and often cheaper, they typically have lower energy density and can suffer performance issues in the cold. (Source: CATL) CATL’s fast-charging LFP battery: ‘The perfect balance’ The new battery achieved fast-charging over a wide temprature range. According to CATL, it can still charge 0 to 80% in 30 mins, even in tempratures as low as -10℃ (14℉). (Source: CATL) Aiken, C. P. et al.

Soc. 158, A74 (2011).The new LFP battery will enable up to 434 miles (700 km) range. CATL claims its new innovation is the world’s first LFP battery to support 4C charging, as well as a “battery for everyone.” For those that don’t know, the “C” refers to the charging multiplier of the battery. Hence 4C can charge in a quarter of an hour.

The electricity that comes into our households from the grid is Alternating Current (AC). Most modern electronics, including EVs, use Direct Current (DC) for their operation. During AC charging of EVs, current from the grid is converted into DC using the on-board inverter, whereas in DC charging, the rapid or ultra-rapid charger converts AC into DC. Cheeseman, H.

Like propellers, LiPo batteries are a consumable in the hobby, however they should last longer than your props, as long as you treat them well! I mentioned internal resistance earlier, this is what kills your batteries over time. The more you use a LiPo, the more the internal resistance increases. Internal resistance can be thought of as a component within your battery that uses electrical energy, leaving less power for your motors. Logan, E. R. et al. Ester-based electrolytes for fast charging of energy dense lithium-ion batteries. J. Phys. Chem. C 124, 12269–12280 (2020).

Schuster, S. F. et al. Nonlinear aging characteristics of lithium-ion cells under different operational conditions. J. Energy Storage 1, 44–53 (2015).There is a phenomenon known as ‘Voltage Sag’– The higher your throttle input, the faster you deplete your battery, but this depletion is not linear. At very high throttle the voltage drops even faster, but as you decrease throttle, the voltage will recover, the lower the C rating of your battery the more pronounced the voltage sag will be, and the longer it will take for the voltage to increase again.

Note – Batteries with a higher C rating will usually be slightly heavier, than others with the same voltage and capacity. Du, Z., Wood Iii, D. L. & Belharouak, I.
