WattCycle 100Ah V2 Rack Battery Tested — Capacity, BMS Protection & Real-World Results

I put the WattCycle V2 rack-mounted battery through real, hands-on testing to see how it actually performs — not just what the spec sheet claims. In this video, I: - Tear it down and look at the internal design - Run multiple capacity tests (both exceeded the rated 100Ah) - Test BMS protection features to see if they actually work - Connect to several different brand inverters Both capacity tests came in over spec, the internal bus bars are solid, and the BMS protections triggered correctly when pushed — which is exactly what you want to see in a battery like this. 💰 Current price at the time of filming: Only $739.99 Save 6% with my discount code: ADAMDELAY 🛠️ Parts & Components (Affiliate Links) WattCycle 100Ah V2 Server Rack Battery 🔹 Website: https://www.wattcycle.com/products/48v-100ah-server-racks-bluetooth-lithium-battery?ref=adamd (Save 6% with my discount code: ADAMDELAY) 🔹 Amazon: https://amzn.to/45GW2nF Klein Tools CL380 Digital Clamp Meter: 🔹 https://amzn.to/3XpZoHc HURRICANE 1000V Insulated Electrician Screwdriver Set: 🔹 https://amzn.to/405ibtQ EG4 Chargeverter - GC | 48V 100A Battery Charger: 🔹 Signature Solar: https://signaturesolar.com/eg4-chargeverter-gc-48v-100a-battery-charger-5120w-output-240-120v-input/?ref=adamd 💡 Want the latest Signature Solar discount code?
