BUT when S5 is connected at rear of unit it shows red only to charge.When i connect S2 it shows 2-3 blue bars (and 7.2volts on meter) all other connection just show red (to charge) now see pic from a web site ?SO how can it show all 5 bars to show 100% full ...it can't ??? ### ⭐ 1.0 out of 5 stars Fails after first use *by R***. on Reviewed in the United Kingdom on 11 September 2023* I have used the battery tester in 7S mode after soldering the pads marked S7 together, I ran power up on my Bench PSU and the red light came on at about 4V then the green lights started to come on at about 24V to about 29V when it showed full.I tested my battery pack and it was at 29V, when I connected the battery tester it flashed and then failed. I tested 3 more from the pack and each one failed either when disconnected from the bench PSU or when attached to the battery pack.I have checked the instructions online and I think I am doing everything right but they keep on failing. ## Frequently Bought Together - DAOKAI 5 Pcs 1/2/3/4/5/6/7/8S Lithium Battery Capacity Indicator Module 3.7V Green Battery Capacity LED Display Board for DIY with 26AWG Wire - Comidox 3S 12V 10A 18650 Lithium Battery Protection Board BMS Li-ion Charger Protection Module Anti-Overcharge/Over-Discharge/Over-Current/Short Circuit 3Pcs --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.gr/products/493353257-5-pcs-1-2-3-4-5-6-7-8s](https://www.desertcart.gr/products/493353257-5-pcs-1-2-3-4-5-6-7-8s) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-05-06*
