if i did add that - and get 5 more miles - it would drain the lead deeper each time - but also what if it fails - then the ADD On wouldnt work - ?
lets say i am 15 miles away when it fails - i have to get back on lead which wont make it from that distance -
Burgerman wrote:That shows your lithium was fully discharged. And say 55Ah from it. And about 15Ah or less from the lead only! So a diode would give you an easy 20% range increase.

Taking this CALB 60Ah cell @£12.50 an example , I wouldn't complain to get a 24V-55Ah pack @£100.00.
It costs even less , if you choose other unknown brands.
I won't take lead any more , even if they were given for free , let alone a £650.00 pair of MK gel out of my own pocket .

Burgerman wrote:Nobody tried this before. So we dont quite know what will happen. For the first few miles you need to monitor the temp of the diode. As it will get hot. To run at high power continuously like up a hill, is the hottest it will get. I think the cables will be enough of a heat sink though. But I am guessing. Its safe to 170C water boils at 100.
You are tester. Did you order a silicon or a schottky diode?
Its small, you will need small ring terminals.

not sure how i would test it - the large hills are not close to me - by the time i test it on a hill - i be far from home - cant have it fail then -
i though you guys done this before ? maybe i heat shrink it and wrap it that tape i got to wrap the pack with - ?
if it needs to be exposed to have Air keeping it cool - maybe a fuse holder to snap over it - if i can find one that would fit , or work etc, ?
