Review on Tenergy 5-in-1 Battery Meter: Intelligent Cell Meter Digital Battery 🔋 Checker & Balancer for LiPo, LiFePO4, Li-ion, NiCd, NiMH Battery Packs by Noel Pilla

I needed a way to control individual parallel groups while the Li-Ion battery was dead and after problems with the type of LED that alternates between elements I decided to do something more to pay and get this item. I have a Tenergy TB6B four button charger that I am very happy with, so I chose this brand. Voltage readings are accurate compared to my multimeter, and the balance function can give an even more accurate result than my charger based on user-selected criteria. The alarm function also has selectable criteria. I'm not sure how the internal resistance is measured, but others say it has proven to be a good relative IR indicator as the parallel groups have aged. So it does a lot more than just accurately measure the voltage of parallel groups of cells, which is why I bought it. It plugs directly into an optional scale socket that I installed because I prefer a more accurate scale than my BMS with TB6B can offer, and now with this 5-in-1 meter I can refine that result even further. I'm very happy with it so far.
