Hi,

I canít find the original which vanished when the Forum went tits upwards and I didnít keep a copy but here is a slightly shorter excerpt of the PM I sent to Victory:

ULTRMAX LIPO BATTERY
Performance.
I replaced 2 x sealed gel filled deep cycle 12v 65ah batteries with one single 12v 84ah Lipo battery. It is an amazing difference. The single 84ah far outstrips the two 65ah batteries in terms of usable power. As described in my review I boat out to a platform, usually do two circuits of a 26 acre mere, two trips to the platform with all the gear ( 1x weeks worth plus dog and bits) put out 3 rods about 3 times a day for a week at up to 250 yds and trips to the portaloo bog and shower. I also let other non boat owners use it if required. With my two lead acid batteries one is usually totally dead by the end of the week and the other is just about hanging in there and the motor is seriously slow on the last couple of trips when packing up to the point I often think Iíll need the oars. The Lipo I used straight from the box at 90% charge and it was still at 70% at the end of the week with the same usage. Amazing. I use a 36lb thrust Minn Kata in a Bic 252 boat.







Weight
My two leisure batteries weigh 55lb each so a total of 110lbs to lug about. The Lipo battery weighs in at 22lb so a weight saving of 88lbs! The Lipo battery has good handle and is an easy one arm lift and can be placed in and out of the boat from the bank or platform without risk of injury. Because itís so light I also take it out of the boat into the bivvy and charge various bits including my two power banks when they run down. The handles on the battery allow an easy one handed lift and carry, whereas the old lead acid required a two handed lift, holding the battery in front of yourself and then shuffling along like youíd shat your pants.



Charger
He charger is included with the battery and is a wall charger. It small and light, slightly bigger then a laptop charger and much smaller than the Halfords car battery charger I use for the leisure batteries. Lipo do have a bit of a reputation of catching fire when charged but these are normally cheap Chinese jobbies sealed in E scooters and hoverboards bought on eBay. I will however charge outside and not risk charging overnight indoors as a sensible precaution.



Availability.
The batteries are available from many outlets including eBay, independent battery companies and Amazon. There is price fixing like with Delkim so itís not normally easy to get a discounted price. Recently however the prices have started to go up. My Battery started to go up from £376 to £441 and each outlet seemed to follow the other in price increase but Amazon is lagging behind at the moment so I quickly ordered one. The prices start at around £300 for a 20 and each 20ah seems to increase by about £20-25



Suitability
As you can see from the use I get out of it on a weeks fishing I went for the 84ah which suits me fine for my engine x boat x usage. Others swear by the cheaper 70ah. For the extra £20-25 I decided 84 was better but 100ah was overkill and a tad too much to pay. Obviously you will base your purchase on your own circumstances.

Tips
Buy a battery usage tester off eBay, costs under a tenner and will show you either volts or % of power in your battery. They are open backed so need sealing.
Have a look in the battery thread in the boat section and download the battery % to power ratio chart on there.
Once you have got used to the battery and have confidence in its power, start to only charge to 90% and donít go below 10% and it will double your lifespan ( although itís not really an issue with it dying after a few thousand charges).



Edit: I forgot to mention that these batteries are fitted with a battery management system (BMS). This is an internal circuit board and chip set which gives the battery Ďintelligenceí to manage itself, preventing overcharge or if you do manage to run it completely down it wonít be damaged like a lead acid battery as it has a low voltage disconnect circuit. Can also c

Basically they are well worth the money.
I got one like in the picture and did two baiting up trips and two night sessions without a charge just before the cold weather hit.
I would recommend especially if you have to replacea normal leisure battery as the£377 I paid
Including a 10A/h charge seams very reasonable.
I found it on eBay and then ordered direct from the company.
Came via a courier on next day delivery.

Hello,
Can the person who posted the review of a Lith battery that got lost while the fourm had its problems.
Repost it as it was one of the best reviews I have read and I'm interested in getting that type of battery.
Even if it's just the model and where you got it from.
Or. Just pm me.
Cheers
Norman
