It would be much easier if you had a special battery drain meter. Otherwise, you should at least have a multimeter, heating wire, alligator clips, and a 2㎡ thick section of wire.

Use wires to connect two alligator clips to create two or four clips. First use one end to tighten one end of the heating wire, the other end to tighten the negative electrode of the battery and the other end. First attach the positive terminal of the battery and attach one end to the multimeter. Use the multimeter to measure the current. If the current is large, extend the distance between the two clips (i.e. move the clips, never pull). the heating wire). You know you need the power, then attach it directly to the heating wire. The capacity must be converted. Generally speaking, a national standard 10 amp-hour battery should be discharged with currentof 5 amps for 120 minutes for a new 20 amp-hour battery. 10 amps for 120 minutes.

Three lithium batteries connected in series will produce more than 12V when fully charged. If the capacity is 7.2 Ah, the batteries should be connected in parallel and then connected in series. The 2800 mAh 18650 requires 3 in parallel and. 3 in series Of course, it depends if the ability is fictional. I used the 3 liter 18650 on a certain battery. The capacity is 2600 mAh and the quality is okay, but I don't know if it has a fake label. It costs more than 10 yuan each and 3 batteries are connected. Series 9 batteries represent approximately 110 batteries. If the quantity is large, you can request it. The seller does spot welding for free.

You must use a 3s balanced charger for charging. Do you want to add one?
