>>11252130It's a voltage issue. If the pack isn't getting the proper amount of power the wand's rumble motor kicking on draws too much and forces a shut down. The pack needs 6V, which is what four brand new D batteries provide. Problem is the voltage decreases as you use them, and in my case the brand new D batteries still ended up not being enough. A popular mod is replacing the D batteries with a rechargeable Talentcell, this being the one most people use

You need to combine the Talentcell with a fan mod to give the pack the proper 6V of power. I'm using the Ghostlab42 keepalive, which steps down the 12V DC power to 6V. There is also a Frutto Technology mod which boosts the 5V USB power to 6V. Either option would work to fix the voltage issue, though you may still get intermittent power loss from the shitty hose connection. I ended up splicing my hose directly into the pack like the OG packs to eliminate any connection issues going forward.
