Thought I would share my journey to get advice and perhaps offer insight to others.
I am about 167 kg/370 lb/26+ st. I do ok with the basic walking around the house but I get issues with extended distances. Big box shops can be iffy at times. Things are complicated by asthma and ankle/toe injuries. The ankle issues are from younger years of thinking I was Wayne Gretzky but being more of a hippo on skates.
I love travelling around the world and in many of the places I go, public transport and walking are vital. This causes me some difficulties. Starting with pwoerchairs/scooters was to address this.
I just got back from my third trip each of about 6 weeks in length since November having visited USA, Germany, Qatar, Korea, Japan, Thailand, Malaysia, and Singapore. In these I have taken two different powerchairs on 25 flights on planes as small as the CRJ all the way up to the 777.
I have purchased off the shelf products from Pride (614HD) and Merits (Atlantis/P710). I can feel the vets here snickering at this.
With little knowledge, my battery experiences have been less than ideal. Recently while travelling, I swapped out the AGM Group 24 batteries in the Merits with drop in replacement LiFePO4 boxes showing 12v 100Ah while in Japan. I had no issues other than being stuck with a 2A charger while there. During one of my transits, I dropped my 6A charger in an airport from a bar height in the lounge. Before returning, I swapped back the batteries not sure of lithium on board airplanes at that high capacity.
The 2 x 12v 100Ah LiFePO4 are being kept at a friend's and since I spend most overseas time in Japan it is not a horrible solution.
Now I have returned home and the chair crippled home with me. I have ordered some MK 75Ah gel batteries that have yet to arrive as replacements for my AGM.
Seeing this board, I am jealous of the amount of knowledge and ability I don't have. I have an engineering degree but not in this stuff. I did my one course in each of the other areas - electrical, civil, materials, etc... but I am well suited for making huge oil refineries produce their optimally - not this kind of stuff.
So first - help!
Second - help!
Third - feel free to ask questions.
Fourth - as far as what I can provide is probably more of the ability to get around the world with my limitations. I am happy to give any insight I can. I like to get around with as little assistance as possible. I like taking public transport from the airports into the cities. I like getting in and out of places that were built for a different age. Yes I have caused damage in my chair to some things along the way that I have had to pay for - recently the mirror in an elevator. Nonetheless I still want to get around and experience things.
