Truck has reduced range due to cell to cell variation in capacity.
-Deep cycling the pack only lasts for a couple of weeks.
-Tried to deeply overcharge the cells.
-Killed two cells in the process, but ruined 3.
-Cannot really afford new pack in this economy.
-No cell auctions this year.
-Gels for Solectria’s might be a good alternative for either truck.
Developed a high powered Lithium bms board.
-Bypasses 3 amps easily.
-At 3 amps the special transistor stays cool!
-Tons of work to figure out how to keep the transistor from getting hot.
-Most amps bypassed on lithium cells that I’m aware of!
-With more work, could be made to bypass 5 amps.
-Limiting factor is how hot the load resistors get.
Purchased a 1991 Honda Accord with 200k miles.
-Should have had a blown head gasket, but did not.

-The car already has many new parts.
-Found a rats nest under the air filter.
-Engine had a sizable hesitation to it.
-Gas mileage was only 20mpg.
-Failing smog test at home with Bar84 analyzer.
-Analyzer turned 30 years old this year.
-Had to replace all of the hardened tubing!!
-Tubing shattered like pasta noodles.
-Now it passed smog with great ease!!
-“I’m free from the plug!!”
-Took Friday and Monday off to work on it.
-Should be finished with cooling system this weekend.
-Vehicle has flat spot and needs some emissions equipment work.
-Good online Honda groups.
– 5 vehicles is too many!!
