“See honey, there are people who abuse batteries worse than I do in this world. The marketing video linked to below mentions someone leaving this pack outside for the whole winter under 7 feet of snow. The BMS on the Ego packs is potted so it is completely waterproof, but the batteries themselves are well ventilated and the Ego packs are not really designed to be waterproof. Using a phase change battery wrap is an ingenious way to capture excess heat Some of these batteries are way better than others, and right now the Ego packs seem to be the best. With the new bunch of high power tools on the market like cordless lawn mowers and chainsaws there are reputable companies that are producing these high power packs for cheap and selling them right down the street at your local Building Supply store. Building your own 25R 14S2P pack from scratch is a time-consuming, expensive and potentially dangerous proposition. HK Lipo’s suck and they are not worth wasting your time and energy with. I pretty much rip on HK Lipos with every article I write and I assure you this one will be no different. In the past if you wanted a small lithium pack that would have <5Ah of power and still produce 25Amps or more of continuous power then you either had to build your own 2P pack with a BMS out of 25R 18650 cells or another high current cell or risk using Hobby King Lipos.
IZIP BIKE BATTERY DEAD AFTER SHORT TRIP FULL
Moral of the story : Don’t marry me if you want your batteries to live a long full life. I did what any loving, supportive partner would do and agreed to pay for half of the replacement cost of the new cells (which will be closer to $1500) then I secretly sneaked away with her $500 lawn mower battery and went to my house for the weekend to extensively test them with my ebike. So I donned an old Spinach container as a face shield and threw on some chemical gloves and carefully disconnected the batteries and carried them outside while trying not to get battery acid all over me. When we returned to the house it was full of smoke and the battery box was over 200 degrees and there was battery acid everywhere and the batteries were squealing and bubbling like crazy.
I recently destroyed $800 worth of 6v Lead Acid Golf Cart Batteries from my wife’s solar system my setting them to equalize for 2 hours right before we left for 3 days to hike in the Catskills with visiting in-laws from Denmark. Fasten your seatbelts because it’s going to be a hell of a ride.Ī 4Ah Ego battery runs about $ 199 at any Home Depot store, Its a better deal if you buy it as a Chainsaw or Lawn Mower package. Instead, this article talks about a very smart way to buy good lithium batteries with a built-in BMS and a decent warranty from your local hardware store, and then mount and use them on your high-power ebikes. This article is not a review for an overpriced cordless lawnmower that you will never buy. The 4Ah battery pack ran for about 30 minutes of hardcore mowing, but it also recharged in about 20 minutes and worked very well with our PV system as long as it was pretty sunny. The mower was powerful enough to knock down most everything (including 3ft high goldenrod) and for the most part, the design was very solid. The next purchase was a much more expensive $500 EGO 56v cordless lawnmower which turned out to be all kinds of awesome. 40v on a lawnmower was a joke your boss tells you that isn’t really that funny but you still have to laugh, so after a few attempts to knock down the overgrown weeds we just took it back. On her own volition without consulting the battery expert she went out and bought a 40v Electric cordless lawnmower (it was probably only 36v and they were just liars). The lawn has a mind of its own (it’s not really a lawn, more like 600 acres of goldenrod) and we decided for our wedding reception we wanted to actually have a lawn for our guests.

Even the generator that we use in the dead of winter is converted for use with propane so we don’t have to deal with the hassle of gasoline. She is also Chemically Sensitive so we don’t really have anything that runs with gasoline except our cars. My wife and I have 2 houses, hers is 1.2 miles from the road up a 900 ft hill and has an off-grid solar system. This article has been a long time coming, but first a little history.
