TYCORUN ENERGY 12V 18AH Battery Opening Review

Let’s see TYCORUN ENERGY 12v 18ah lithium-ion battery together in this video.

TYCORUN ENERGY 12v 18ah lithium ion battery specification

This is the TYCORUN ENERGY 12v 18ah Li-Ion battery that I am going to test right now. The nominal capacity is 18ah, and the nominal voltage is 12.8v. 14.4V charging voltage, maximum charging current 14.6V, maximum standard charging 20A, maximum continuous discharge current 20A, 12v 18ah lithium-ion battery operating temperature minus 20°C to 60°C. Look at the 12v 18ah battery on the right, there is a caveat, it has a storage capacity of 50. If you look at the top of a 12v 18ah battery you will see negative and positive terminals.

Check out TYCORUN ENERGY 12v 18ah lithium-ion battery capacity

There are Phillips screws, washers and lock washers. Then check the capacity of your 12v 18ah li-ion battery with this little tester. This tester can read the last amp-hours and watt-hours. The positive and negative terminals are connected to a 12v 18ah lithium-ion battery and plugged into a wall adapter. Operating current is 3.6 amps. The final result took 18.05 amp hours. Its capacity is acceptable.

TYCORUN ENERGY 12v 18ah lithium-ion battery internal structure

Let’s unpack this battery and see what’s inside. The battery has 12 gauge wire and is rated for 200 degrees. There is also a foam that keeps the battery firmly in place inside the battery. The bottom has double-sided padding, and the battery pack is completely encased in fiberboard. It’s a great insulator.

If you cut it open, the battery pack has a cylindrical cell, the BMS. Fibreboard separates the batteries. There is a sh2140b 714×3 in the BMS, it’s Chinese, but it’s probably 27 amp charging and 30 amp discharging. You can see some filler, but the solder is nice and shiny. A temperature sensor is connected to the battery.

Test TYCORUN ENERGY 12v 18ah lithium-ion battery cold disconnect

It might just be hot, but I’d also test it cold. The solder on the battery is nice and shiny, which means my solder has reached the perfect temperature. The battery is marked wtt32700, 6000mA, 3.2 volts nominal. It has a date of manufacture. So this 12v 18ah Li-ion battery is brand new.

I’m charging at 5 amps now, let’s see if the cold disconnect works. The battery has a low temperature disconnect function. Let’s reheat it. Once it warms up, the battery starts charging again. With this cold cut feature, the quality is really high.

Next, let’s check out the temperature protection. Let’s see what happens with a heat gun. The battery will turn off. This TYCORUN ENERGY has some high quality batteries with very good battery construction.

summarize

Searching the YouTube channel, TYCORUN ENERGY shows a lot of what the company keeps secret. For example, there are battery assembly lines and battery pack lines. Such batteries can be used in devices such as lawn mower batteries and forklift batteries. This is a grade A battery, we recommend TYCORUN ENERGY 12v 18ah Li-ion battery.
