Love to see how the solar panel on the top works out.

So many advantages there changing to that single LifePo4 battery, e.g. no more topping up of over a dozen cells with distilled water, no more acid corrosion of the terminals/ posts/ wiring, and a higher sustained voltage while discharging ( driving longer between charging ) . Was a bit surprised only 1 battery was needed to replace those 6v batteries ! Guess you won't be going back to deep cycle lead acid anytime soon.

Great! I have a golf cart that hasn't been used & needs an upgrade, a solid solar panel and an elderly mom who would love to get out more. Thank you Emily & Clark! (Besides I have to contact you concerning the battery manager for my sailboat) Ah well. Great idea & use. Be well.

Good episode. Quite the difference. 300 lbs is crazy. In drag racing, 10 pounds weight reduction is equivalent to a 1 hp gain. 300 would be like having an extra 30 hp.

Almost as good as top gun. Cool upgrade i have 2 older12v li time 100w . Thanks guys

So crazy, I wanted to reach out about what to buy for a golf cart!

Re: cold temp charging: It would make sense to me that if you have power to charge but can't because the temperature is low to use that power to heat the batteries till they are able to charge. Even outside at -10C or more, there is enough room to put a heat rope around the battery and still fit foam insulation.... but, Florida prolly doesn't need it :)

The video was fun but it was no surprise that the speed difference was not that much. Speed is a mix of both current available and the voltage. However, what should have been much more of a surprise would be the range. Certainly the comparison of 100AH to 130AH is a very small part of the story because the depth of discharge available. I would expect much more than a 30% range increase. Also, aside of a longer range, I suspect the get up and go would show less deterioration when the "tank" is almost empty which the difference between 33V for LA and 40V of the Lifepo4 (at end of range).

Edit: I see someone else figured he started with 50AH, but I thought they were 100AH. Sorry if I got it wrong.

Hi Mr Clark 😊 solor
Would you think a carbon battery can be a choice with lithium
Like 200 amp carbon/200 amp lithium or would their be a better choice on mixing amp with veritable chemistry
2 answer would be fine

Thank you
Clark I have To do a lot more thinking then dreaming I've lived on Solar 1.4 kw for 7 yrs
Need more $ to start the retirement that coming 😮
Got carried away DETAILS sorry. Thanks
Carbon blend with Lithium

I thought they were going to be testing a lithium battery that has the CG2 standard dimensions.
I would be interested in that, as my battery storage onboard has been built around the CG2 lead acid batteries, and I haven't found lithium replacements that don't cost the earth.

Does the app have a pin code to "lock" the battery? If it's an expensive item, thrives would soon learn all you need is a free app .

Clark. What is the advantage of Bank Manager if not combining Pb/acid with LiFePo4?

I switched my battery arrangement after I purchased my Bank Manager (purchased for 36VDC system). I now have 48VDC system (Pb/Acid and LiFePo4) and want to set up my Bank Manager for the first time. It came with three resistors (I think because of 36 volt system) and no schematic for the resistors installed in the Bank Manager circuit. What arrangement do I set up with my system now at 48VDC and my Bank Manager? Do I need another resistor, no resistors, Thank you!!

Let your partner in crime know that the review was very appreciated.

[paulwyand]

Of course not only do you have more amp hours, but you can use more of them. So he went from 50 amp hr to like 110, so he should get about twice the range.

[ChipShot]

Ok, flat tire. Why not do another speed test? Is his time more valuable than mine?
