Has anyone had an issue with the PW-1000 or PW-999 similar to the following: The chair seems to have difficulty when maneuvering at certain angles (typically straight left or right). The chair will shake/shudder while making the turn, or will not move at all at certain angles. The chair (PW-999UL) is less than 2 months old, and did not this issue before (may have developed gradually); was much smoother during turns before. The battery is fully charged, so that shouldn't be it. At first I thought the wheels were getting stuck on the carpet, but it also happens on flat surfaces. Perhaps an issue with the front wheel orientations obstructing the turn? The chair does leave wheel marks on the carpet during these problem maneuvers.
Any ideas? I contacted wheelchair88 & they asked me to send a video, which I will do in a day or two. Other than that it is a great chair. Thanks everyone.
Not had such problems with my PW-1000XL so far, but can get into problems where the chair decides to go down a steep slope its own way, but my Otto Bock B500 has that same feature (more grip though so easier to stop it).
I've always found the PW-1000XL has far fewer problems turning at low speeds than the B500, which is programming & the lead bricks that are about to get replaced with a lot of 15Ah LiFePO4 cells.
I'm about to build a new battery pack for the PW-1000XL, same plugs but won't be connected at the same time as the original lithium polymers, I'll report back on how that works out as the voltage will be a bit lower & it may cause the motors to stall in a turn without a change to programming, but I doubt it. Going to set up a seperate charge port on the liFePO4 pack so I can charge it with the PL8, same as the Otto Bock's larger pack (105Ah as opposed to 30Ah for the PW-1000XL).
