Hello Richard Great to hear your doing well with the truck. You noticed in time to be a bit more conservative and increased you range. It's too bad the heat pump uses so much power I usually drive around with it off. Gloves really help when holding on to a freezing steering wh...

Lynn, Ebay is a very fickle marketplace, as we seen dead S10 EV's have gone for almost 15K, with almost assured more problems than just dead batteries. I'm not Ebay Power seller but in my auctions I have gone through enough trial and error in selling that have lead me to four...

There is a price to be paid by not charging the S-10EV to full, and outweighs the benefit of not charging to full. I'll explain. Each of the 26 NiMH battery modules exhibit a slightly different impedance and parasitic discharge rate. Differing module temperatures occur due to...

I don't have the data to back up my opinion, but I think full 100% charging does shorten battery life. On the Toyota Prius, the NMH batteries are cycled between 40% and I think 85% SOC. They could get the most life out of their batteries in this range. This makes sense to me....

As far as I know, charging the battery to full does not reduce the service life of the batteries. I don't think that is what Don was talking about. I think Don was referring to the fact that if you charge your pack to full and then let it set for a few hours then it will have...

A quick telephone call to the manufacturer disclosed that their product probably *will not* work with the S-10EV. But you're welcome to buy it, and try it, and possibly eat it. Not likely they'll accept a return. That's why they want you to check the compatibility list first....

It's that time of year to check the cooling efficiency of your NiMH S-10EV. Maximum efficiency is critical in limiting wasted watts during charging of NiMH batteries, along with passenger cabin comfort during driving. If the heat pump runs continuously during charge, then your...

My sense is that some RAV4 folks use the 40%-80% range SOC because that is what Toyota has programmed into the Prius, presumably to extend the battery lifetime of the NMH hybrid batteries. This was done because California requires 150,000 miles (I think) on the system. That is...

Richard, the correct quantity is 32oz. Effectively 2 1/2 twelve ounce cans of R-134. Additionally, if the system is dumped, you'll need to add a minimum of 8oz of Ester oil, and no more than 10oz. Yes, the system spec is for 13oz Ester oil. A considerable amount remains in the...
