🔋 DZS Elec 2PCS 2S 18650 Lithium Protection Board 7.4V 8.4V 8A BMS PCM Charger Protection Board for Li-ion Lithium Battery Cell with Enhanced SEO Review

I installed this component into the power/battery charging system of a toy robot I was working on. Great for charging batteries.

This worked well to protect a project I was working on. I was using two LiPo batteries (2S for two cells) and needed overcharge and short circuit protection. So far everything works great. tips; Make sure both batteries are the same brand and capacity. Both batteries should have the same capacity, a balanced charge is important.

Missing information, hence only four stars. For those having trouble, make sure the two batteries are balanced and not at full capacity. Then charge the batteries through the BMS, then your BMS will work properly. I went through a bunch of them thinking they were all bad until I found some good documentation about them. They are designed to stop working if the batteries are too badly unbalanced.
