Had a good increase in battery range, due to the fitment of Radials and I installed an x-brake disc handbrake in place of the drum handbrake , the shoes were oil soaked in usual Series LandRover style, which must have created considerable drag. Todays test drive managed 65km with 50% charge remaining, happy with that.

Maybe some 7.50/R16 radials would suit a bit better.Quote:

This is also the reason I took the overdrive off - absolutely no need for it. Would be even better with a 1:1 High range transfer box , the Series is 1:1.148 high.
With the smaller tyres I theoretically get more battery range and though I can take off and drive around town in 4th its happier in 3rd gear & I just slip it into 4th for the highway , mainly to cut back on gear noise.
With reference to the graph, its not always pulling 450 Amp at 100kph , only if you have your foot flat to the floor & accelerating , most driving around is between 50-200 amps .

You've obviously given this plenty of thought!Quote:

Yes, 4th is direct drive from input shaft to output shaft , giving the layshaft no stress, but the gears being in constant mesh are all still turning. I tried thinner synthetic oil to reduce drag but finds more places to leak !! 4th is a lot nicer on overrun too because regenerative braking puts reverse load on 3rd & does not sound happy, so I back off regen if using 3rd .Quote:

You bringing this over to Corowa? Would love to look over it in person. 👍
not sure , is there somewhere with a 15Amp power point just incase ?Quote:

The caravan park we are staying in is full of 15 amp outlets. 👍 We stay in an unpowered area, but there are permanant sites directly opposite that no one uses that week which I sure you could avail youself of.
Saturday 17th March is the main day with the parade through town and the swapmeet up at the racecourse. After lunch the river behind the Ball Park caravan park becomes the main area of attention.
Plenty to see and do.
I rang the Caravan park , no powered sites left I'm afraid, I explained the situation and they suggested I could use a powerpoint in the Camp Kitchen to charge an R/C Car , hmmm .
Corowa is right on the range limit for a trip there & back , If I buy a generator I'll come over for the Saturday otherwise happy for you to visit here if its on the way / way back , or Lunch at Club Mulwala (RSL) one day .
I wasn’t going to tell them you were going to plug it in, just use a spare outlet on one of the permanents that won’t be there.[emoji56]
All good - happy to meet you somewhere too no dramas. I’m at Corowa all week so if you’re available during the week I can meet you somewhere. [emoji106][emoji4]
