The Optimate Lithium 0.8A 8 stage charger is ideal for charging the pbq 10Ah LiFePo4 batteries.

This charger is ideal if you intend to keep your batteries connected for long periods of time or for batteries that stay in the glider and you wish to leave them charging overnight.

See below for the 8 stages of connectivity.

More Information

The 8 stages of connectivity:

1.       Pre-qualification / BMS reset: The charge program is selected according to battery voltage. For batteries with internal BMS (battery management system) that includes a low voltage cut-out; OptiMate Lithium has a BMS reset program to reconnect the internal cells with the battery posts so that charging can commence. 
2.       Low Volts recovery: The OptiMate SAVE mode controls charging during this sensitive battery SAVE stage, to ensure that an over discharged battery will be correctly and safely recovered. Tests are conducted through-out the SAVE program to determine if the battery has successfully recovered and can advance to BULK CHARGE. 
3.       Bulk charge stage: Charges at 0.8 Amps constant current until the Voltage has risen to 14.3V.
4.       Short-circuited / dead cell check: Charge progress is tracked against the ideal LiFePO4 charge curve, internal damage will be detected and unnecessary charging is prevented of a battery that cannot be recovered. 
5.       Absorption and equalization: for up to 4 hours the current is delivered in pulses with voltage controlled between 14.0 and 14.3V, aiding cell voltage equalization and improving the battery's overall power delivery. 
6.       Voltage retention test: is conducted for up to 12 hours during which no charge current is delivered, with 3 possible test results indicating the battery's general state of health or excessive self discharge or higher than expected power loss through the vehicle’s electrical system. 
7.       Charge maintenance: The MAINTENANCE CHARGE CYCLE consists of 30-minute float charge periods at a voltage of 13.6V followed by and alternating with 30-minute ‘rest’ periods. During the float charge period current is delivered only if the battery has lost charge due to connected vehicle circuitry. A refresh cycle may be performed if the charge level has dropped significantly. 
8.       The alternating charge and ‘rest’ maintenance program protects the battery against over discharge by connected vehicle circuitry, making it ideal for indefinite and 100% safe long-term maintenance charging.

Replaced old batteries with new lithium one's which require this special charger. All works fine, does mostly take overnight to get a full charge ie two full green lights.

Good LiFePo4 charger
12 June 2020  | 

Good charger for LiFePo4 batteries and can save a battery that has bee discharged too much. Simple plug and play operation and can be left connected for extended periods. The only downside is the charging rate of 0.8A is quite slow and cannot charge a fully discharged 10AH LifePo4 overnight.
