Are companies that sell LiFePO4 batteries online that risky? What amh is best for 48 v battery, 10, 12, 15, 20 etc?

I've had luck with Alibaba Express (which takes credit cards, unlike regular Alibaba which requires TT or wire-transfer). I got a 48v LiFePO4 20ah for cheaper than what I was seeing in the US (even including the shipping from China). So far it has worked well and hasn't started anything on fire. Ali-express is similar to ebay, so don't buy from a seller without many reviews. If you get LiFePO4, you need a specialty LiPo charger (it senses voltage level of the battery and turns itself off).

I would be safe and purchase an amh of at least 15. The higher the better. I would check customer reviews to see how the seller rates among competitors.

The best price batteries I bought were from hobbyking for lipos. Prices vary depending on witch size you go with. Most all of them are decently priced.

I just use regular batts and avoid all the fuss. Ni-MH batts will can't hold their charge very long at room temperature as well as alkaline varieties, are pretty pricey compared to alkaline, and eventually will die out too (or reach a point where their half-life makes their use totally inefficient). Flip runs quite well on normal AA and I never have to worry about overheating/charging or any issues many of the 1-star folks bring up.

There's PowerEx but there's been some problems with those even though many people probably are fine with them they are not really low Self Discharge batteries. I highly recommend the high capacity Eneloops but you could try the PowerEx's but i'd read the reviews first to see if you really want to get them.

I bought a Ridgid AC840083 - X4 18v 3.0ah Hyper Lithium ion Full Capacity Battery,Sold by Innovative Emporium. I looked at the ad for the battery you bought from another seller. If I had bought based on the ad I would have expected the charger too. Though a battery and a charger for that price would be a steal. It seems to me that they owe you a charger. At any rate you got a good battery at a good price. Best of luck. Stan

The ones I have bought always said TMS on them. Just don't buy from buy4easy. I will say they are great batterys.

The one that I use is the Sony DCR-VX2000 Camcorder Battery Lithium-Ion (6900 mAh) http://www.amazon.com/gp/product/B00301UMEK/ref=oh_details_o01_s00_i01?ie=UTF8&psc=1 If the light is not on full blast I can get over 4 hours out of it. At full, maybe three. there are some disadvantages to the size of this battery...namely the weight. at times it is too heavy for the light mount and (unless screwed in tight) can tip over. my suggestion get one large battery and one regular battery. the more varied your bag the less likely you will be in a pinch. either way, great light! all my friends in NYC were floored about how good it is compared to the competition

18650s four each make sure you buy the batteries with the internal protective circuit in it for safety's sake. My recommendation would be: Welltop® 4Pcs 3.7V 18650 5000mah Rechargeable Lithium Battery with Battery Charge+ Free Welltop® Corkscrew. This a Prime so shipping is free. These have the extra power and the internal protection, the quantity you need and a charger = Great Deal, Enjoy.

you definitely want the 18650 battery. Less expensive in the long run but more importantly it is a 3.7 volt so you get more juice out of it, brighter light. I NEVER use AA or AAA if there are other options.

Would you tell me the brand of the NiMH batteries you used? I have problems to find suitable ones.

I own UltraFire and Tenergy Brand of 18650@3000ma. I have 5 set of them. I only had 1 bad one that won't hold a charge in storage. The rest seem fine I measure the voltage on them to check. After a fresh charge it measure 4-4.3 volts. Then it drop to 3.8,4.1 for over about 2 month. I think like everything a little luck is involve. I read the other peoples reviews and 4-2 stars to me if the price is right I'll take a chance. So far it a good deal Beside they are all made in CHINA no matter which brand. The Trustfire charger works fine too. Voltage on batteries checked before this reply...

Alan: You'd have to check with the manufacturer because I'm not sure if the charging rate is the same for NiMH and Li-ion technologies. But I wouldn't use NiMH 9v batteries anyway because of their relatively high self-discharge rate. I want to be sure that when I need the battery, I won't find it dead.

To the best of my knowledge, any decent NiMH should work.... Its my opinion that the low discharge rate batteries, such as Imedion or Eneloops are the best batteries available these days, not since they offer the greatest capacity, but since their low discharge rate allows them to sit unused for greater periods of time, and still deliver when needed. A device such as the PortaPow might sit in your glove box for months or years before being needed. To then find the bats dead makes no sense. If you are using the portapow daily, well, I'd think there are better ways to charge your portable device....

If you can find a 5900mAh rated battery, it would be better. the higher the number, the longer it will run on a charge. When you buy any of these generic batteries, try to make sure you can see an accurate picture of the side of battery that has the battery info and make sure it's in the item description so when you buy it, and it turns out you get jipped, you can throw that in the sellers face. Too many sellers have descriptions with their items that are not what they say they are.
