it could have grimy battery contacts. come across a sprint bit superb sand paper and clean all the battery contacts.

The modules are stacked side by side and then compressed together in a rigid, non-expandable structure that prevents expansion from internal pressures.

Discharge power capability of the Prius pack is around 20 kW at 50% SOC with regenerative capability of 14.5 kW at 2C. The power capability increases with higher temperatures and decreases at lower temperatures. Active thermal management can improve power capability at lower temperatures.

Q:What cable do Venom Xbox rechargeable battery packs use?
Hey! I'm not an expert in the matter but I once bought a set of battery packs like these with the same recharge chords. It's just a regular USB cable input with a certain plug on the other end which appears to be purposely designed for these battery packs as I've never seen it before. Except maybe with some phones? You wouldn't be able to buy them seperate I wouldn't imagine unless you went to an electronics store, but if you'd like an extra spare battery pack with a new cable, these ones should be the same ones as your looking for: I live in australia, but i'm assuming your from the UK, as the amazon link was I hope i've helped, sorry for the long read. Cheers!
